I've figured out a way to capture video on wayland (hyprland) with ffmpeg, but that method does not cover audio. Most people on wayland will be using pipewire, pipewire has a compatibility layer for pulseaudio called pipewire-pulse which allows most audio designed for pulseaudio to be played or recorded through pipewire. But in ffmpeg's case it doesn't seem to work. ffmpeg -device /dev/dri/card1 -vaapi_device /dev/dri/renderD129 -f pulse -ac 2 -i easyeffects_sink.monitor -c:a libopus -framerate 60 -f kmsgrab -i - -c:v h264_vaapi -rc_mode QVBR -q:v 10 -maxrate 327680 -b 81920 -pix_fmt vaapi -vf hwmap=derive_device=vaapi,scale_vaapi=format=nv12:out_range=full out.mp4 The above command fails with Option device not found. Error opening input file easyeffects_sink.monitor. Error opening input files: Option not found But if I remove this part: -f pulse -ac 2 -i easyeffects_sink.monitor -c:a libopus It will work relatively fine. and if I am on x11 instead of wayland, using x11grab instead of kmsgrab ffmpeg -vaapi_device /dev/dri/renderD129 -f pulse -ac 2 -i easyeffects_sink.monitor -c:a libopus -video_size 2560x1600 -framerate 60 -f x11grab -i :1.0 -c:v h264_vaapi -rc_mode QVBR -q:v 10 -maxrate 327680 -b 81920 -pix_fmt vaapi -vf format=nv12,hwupload out.mp4 That command works perfectly fine even if it uses the exact same options that didn't work on kmsgrab. Which leaves me with the question of whether ffmpeg is capable of capturing audio from a wayland environment at all.

I have a system with two audio cards: a Scarlett 2i2 where I have connected two speakers and the HDMI monitor, where I have connected the headphones. It is also possible I connect at some point some Bluetooth headphones. I have created a null sink where I connect all the audio applications, and I would like to automatically connect this null sink to my hardware audio devices. Since the Bluetooth headphones may be present or not in the system, I guess I need to do this dynamically, so I need Wireplumber, but I have no idea how to do it. I have added my Pipewire graph. In blue, the applications playing some audio, connected to easy effects input. In red, the easy effects pipe, connected to my output null sink. In white, the hardware audio devices. These are getting audio from the null sink. These are the connections I want to generate automatically, as right now I have to connect them by hand when I boot the computer In yellow, the microphone pipeline. How should I perform the connections from the null sink to the hardware devices automatically?

I own a pair of USB mono Apogee HypeMiC and need to create a virtual stereo microphone (one mono mic per channel) for OBS. I believe that these are the two mics: pw-link -o | grep -i 'input.*hypemic' alsa_input.usb-Apogee_Electronics_HypeMiC_1111111111111111-01.mono-fallback:capture_MONO alsa_input.usb-Apogee_Electronics_HypeMiC_2222222222222222-01.mono-fallback:capture_MONO Google AI suggested me this command: pactl load-module module-remap-source source_name=virtual_stereo_mic master=alsa_input.usb-Apogee_Electronics_HypeMiC_1111111111111111-01.mono-fallback,alsa_input.usb-Apogee_Electronics_HypeMiC_2222222222222222-01.mono-fallback channels=2 master_channel_map=front-left,front-right channel_map=front-left,front-right source_properties=device.description=VirtualHypeMiC Unfortunately, it does not work as expected. In OBS, when I select the virtual stereo microphone (VirtualHypeMic), on both channels I get the audio picked up by the microphone of my right AirPod (AirPods 3rd gen.). The two USB HypeMics remain off with the usual solid-blue LED (tapping either mic generates no signal level spike on the VirtualHypeMic, only tapping the right AirPod makes the signal jump into the red zone immediately).

Why do I get this in the console when restarting plasmashell with killall plasmashell and kstart5 plasmashell in Debian11/KDE with Wayland and how to solve the problem? Of PipeWire I currently only have libpipewire-0.3-0 installed, I searched for screencast in Apper but don't have anything of that installed. I'm using PulseAudio and I think I also got this error when I ran something else than plasmashell but it's probably the same cause. I'm not screenrecording but have some apps that can do so. I tried uninstalling xdg-desktop-portal and this reduced these errors but the error still shows, it went from 8 times the above error to only one:

error creating screencast "Failed to connect PipeWire context"
trying to show an empty dialog
DataControlOffer: timeout reading from pipe
DataControlOffer: timeout reading from pipe
DataControlOffer: timeout reading from pipe
DataControlOffer: timeout reading from pipe

**Edit**: it's two errors now and unlike before these only occur after waiting for approximately 20 second after starting plasmashell (the other errors are because of kdeconnect trying to start without being configured to so which I blocked and asked about separately):

...
error activating kdeconnectd: QDBusError("org.freedesktop.DBus.Error.Spawn.ExecFailed", "Failed to execute program org.kde.kdeconnect: Permission denied")

kdeconnect.interfaces: dbus interface not valid
error creating screencast "Failed to connect PipeWire context"
error creating screencast "Failed to connect PipeWire context"
libpng warning: iCCP: known incorrect sRGB profile

**Edit 2**: this error does not occur on another machine with nearly the same setup. Plasmashell is version 5.20.5 in Debian11. The same error occurs again when waiting for a while. How can I find out the source or traceback of this error message (may be a separate question)? I'd like to find out what software causes it, it's probably something that plasmashell launches. **Edit 3**: after upgrading to **Debian12** and resuming from sleep these lines show in journalctl shortly after resuming. Why and what should I do:

systemd: NetworkManager-dispatcher.service: Deactivated successfully.
kwin_wayland_wrapper: kwin_screencast: Failed to connect PipeWire context
kwin_wayland_wrapper: kwin_screencast: Failed to connect PipeWire context
plasmashell: error creating screencast "Failed to connect PipeWire context"
...

Is there some problem with kwin_wayland or a pipewire package missing? It seems like many people get these messages so some further information would be useful.

"internal microphone" in Alsamixer is not muted, and is set to the highest possible volume. The GUI pavucontrol also matches fine with what pactl is showing me (Internal microphone is being recognized, but not picking up anything). My audio profile in pavucontrol is "Analog Stereo Duplex". Don't quite know where to go from here.

I'm currently using Ubuntu 25.04, and there's a problem that's been bothering me: the system's volume adjustment doesn't work. When I slide the volume slider, the actual volume of my USB speaker doesn't change - unless I turn the volume down to 0, muting works fine. I can see that my USB speaker has two PCMs in alsamixer - PCM and PCM 1. Only adjusting the volume of PCM 1 has an actual effect. I suspect that the system's volume operation is on PCM, so it doesn't work. I looked up some information and learned that Ubuntu now uses pipewire to control the volume. But I don't know how to verify my conjecture or how to fix this problem. Can someone help me?

I'm using Pipewire in Arch Linux there seems to be an annoying problem with loud popping whenever the sound card is activated and deactivated. Is there a value that can be set to extend the suspend time to like 24 hours or something. Which file would I access to apply this?

I have an app that is play music to the default audio device (which uses pipewire). When I using a second play command (pw-play) the command executes but that audio is not heard. I was hoping to merge / combine the two audio streams. Is there a way to cause the audio to be combined? (Instead of the first play command only being heard) **UPDATE**: I did have problems getting sound to play (from a service running as root). So I created a script that runs pw-play using sudo, and that seemed to work on its own. When I run the script (from the service) I hear audio play. But, if I'm playing music (using shairport-sync) and then run the script it will not result in additional audio being played. Using 'ps' I discovered that a bunch of my playback scripts are in state code S, so are suspended and waiting on something. Even the speak-test I ran is in S state. I tried restarting the shairport-sync service but that did not allow the other processes to continue. I'm not sure how to diagnose this - how can I figure out what these stuck processes are waiting on? If pipewire is supposed to merge audio then it shouldn't block the scripts...

I'm having trouble with audio output on my Arch Linux setup. While audio works fine through both wired and Bluetooth headphones, I can't get any sound from the built-in speakers. I have already tried the following steps to troubleshoot, but so far nothing has fixed the issue: Setup Details: OS: Arch Linux Audio system: PipeWire (PulseAudio module) Audio Device: Intel Tiger Lake-LP Smart Sound Technology Audio Controller (using snd_hda_intel driver) Steps Taken: Checked the output device status with pactl list short sinks: The built-in audio device (alsa_output.pci-0000_00_1f.3.analog-stereo) is shown as "SUSPENDED." I've attempted to resume it using the following command:

resume alsa_output.pci-0000_00_1f.3.analog-stereo

But I receive the error "No valid command specified." Verified that the audio device is not muted in pavucontrol: The device "Built-in audio control" is selected, and the volume is not muted or set to a low level. Tried playback using paplay and aplay with the following:

/usr/share/sounds/alsa/Front_Center.wav

But I hear no sound from the speakers. Playback works fine with headphones (wired and Bluetooth). Checked ALSA configuration: There are no apparent configuration issues (no ~/.asoundrc or /etc/asound.conf files). Tried restarting PipeWire and PulseAudio with the following commands: systemctl --user restart pipewire systemctl --user restart pulseaudio After restarting, I still can't hear sound from the speakers. Checked volume settings with alsamixer: The volume for the "Master" and "Speaker" channels is set to a high value and not muted. Tested the audio device in a different user account: I created a new user and logged in, but the issue persists even in the fresh environment. Confirmed that the speakers work in Windows (dual-boot setup), indicating that the hardware is functional. Additional Information: The audio device is correctly recognized by the system and using the snd_hda_intel driver. I have confirmed that other devices (headphones) work fine. I cannot find any relevant errors in the system logs.

On Debian with Pipewire and WirePlumber, I'm getting,

i have a new laptop and thought ill try using Arch Linux for the first time and everything except the audio works like a charm, which was unexpected. My Problem is that, if i try to change the volume it does not change the real sound that gets played, so 5% and 100% have the same sound volume, i can see in the alsamixer that the "Master" Volume gets changed which has no impact on the audio. If I change the "PCM" volume in the alsamixer the audio does correctly change. After a lot of googling and "prompting" chatgpt i can't seem to find the root cause or a fix for this problem. I dont want to use the "alsamixer" everytime i want to tweak my sound volume, i have volume keys for that :( Can someone point me in the right direction or give me some other hint on what i can do ?

I was attempting to connect to a Google Meet call on my browser (Chromium) and where it would normally have found my USB audio device (a USB dongle that I can connect a microphone and line-out/speaker on their own 3.5mm jacks) for some reason it no longer was. Going into pavucontrol and my volume control applet, and so on, did not detect the device. As mentioned, this used to work no problem, with me connecting, disconnecting, reconnecting the USB dongle at will (and where it is normally not connected, for privacy reasons).

Using Linux Mint. Anyhow - the problem in question: whenever I log out or the computer sleeps or anything that makes my bluetooth reconnect or autoconnect (even after reboot with the headphones on, for example), my bluetooth Sony headphones only have the handsfree profile, and not the A2DP-sink, making the audio quality absolutely terrible and the noise cancelling weird. I have installed libpipewire, pipewire, pipewire-alsa, pipewire-audio, pipewire-bin, pipewire-locales, pipewire-pulse and blueman. My main.conf file has:

AutoConnect = true
MultiProfile = multiple

I otherwise see this error in pipewire when I check the daemon status:

and this one on the bluetooth:

I tried searching the forums, tried a few solutions on the web (one of them suggested this MultiProfile config in the main.conf file) and tried AI help without any solution. Any help would be appreciated. Thanks!

I am running arch Linux with an asrock b650 motherboard and pipewire refuses to find my sound card. In a comment below is the output of various journalctl runs that will hopefully prove useful if anyone can advise on how I can get pipewire working. I have already tried uninstalling and reinstalling to help. Edit: I am unable to post that output as a comment as the length exceeds stack overflow limits. Below is a small section of the journalctl that will hopefully prove useful:

With plain ALSA there is alsa-restore.service which restores soundcard states after system restart (volumes, mute switches, etc.). I'm interested how to achieve the same with PipeWire/WirePlumber. For some reason after restart my headphone output is muted, and some other settings are reset to some default state. alsa-restore.service doesn't work, because PipeWire/WirePlumber overwrites the settings when started. WirePlumber Lua configs are very complex and I'm unable to understand it. I'm asking for help.

Audio lags for a second-two, than normalizes. It was observed only for audio in telegram messenger. External DAC is used, therefore corresponding pipewire sink is selected. What is the reason of this behavior and how to fix this?

I cannot for the life of me resolve an input/source issue I'm experiencing. **Expected Behavior** When using: Digital Input (S/PDIF) - SteelSeries Alias Pro OR Analog Input - SteelSeries Alias Pro I am able to use the XLR Microphone connected to the DAC/USB Device. Note - Both inputs worked previously. I understand the SteelSeries Alias Pro is a USB DAC, I do not use it for Audio Output, Audio Input only. I know the XLR Microphone is 'receiving' me, as there is a light indicator that indicates sound is being picked up over the XLR. **Reality Now** When selecting an Audio Input (Source), I can still select either S/PDIF or Analog for the Alias Pro - there is a momentary 'activity' detected, but that doesn't seem indicative of anything at all. Tapping on the mic, talking into the mic, et. all produces no 'activity' detection. I have tried using a headset microphone in the interim, though interestingly that comes out way too quietly even at max volume.. (I have not tried boosting to 150%, just up to 100%). The headset in question is a SteelSeries Arctis Nova Pro Wireless. **Troubleshooting Information** lsb_release -a

pulsemixer inputs pulsemixer cards gnome settings/sound edit - dropped the '2' from Alias Pro. The '1' and the '2' come from whichever USB port you're plugging into on the device itself.

Using GNOME, bluetooth headphones won't show up as available sound output/input options; if I restart the pipewire service via systemctl restart --user pipewire, they do show up. * Wifi/Bluetooth card is the following, as show through lspci:

29:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)

* There's a single line of log after disconnecting and reconnecting my wireless headphones, in order to reproduce the issue for this ticket:

-shellsession
    $ journalctl -ru bluetooth
    Jan 17 18:22:14 cerberus bluetoothd: No matching connection for device

* And there are no pipewire logs at all. Any pointers? * Before restarting pipewire service: * After restarting pipewire service:

My goal is to alter my voice in a particular way and redirect it to MS Teams. I managed to pipe my voice from my headphones microphone to a virtual microphone named wh40k like this: parec -d $PHYSICAL_MIC | sox $FILTERS | pacat -d $VIRTUAL_MIC. In detail, this is my code: VIRTUAL_MIC="wh40k" # Hard-coded headphones microphone name which I got from pactl list PHYSICAL_MIC="alsa_output.pci-0000_00_1f.3-platform-skl_hda_dsp_generic.HiFi__Headphones__sink" # Check for required software: quit if any not found for CMD in parec sox pacat; do if ! command -v "$CMD" &>/dev/null; then echo "Error: $CMD not found.." exit 1 fi done cleanup() { echo "Removing virtual microphone $VIRTUAL_MIC..." pactl unload-module "$MODULE_ID" exit 0 } if ! pactl list sinks short | grep -q "$VIRTUAL_MIC"; then echo "Creating virtual microphone '$VIRTUAL_MIC'..." MODULE_ID=$(pactl load-module module-null-sink \ sink_name=$VIRTUAL_MIC \ sink_properties=device.description="$VIRTUAL_MIC") if [[ -z "$MODULE_ID" ]]; then echo "Error: could not create virtual microphone '$VIRTUAL_MIC'." exit 1 fi else echo "Virtual microphone '$VIRTUAL_MIC' already exists." fi trap cleanup INT TERM echo -e "\nConfigurated sinks:" pactl list sinks short echo -e "\nConfigured sources (monitor):" pactl list sources short echo -e "\nConfiguring '$VIRTUAL_MIC' audio pipeline..." # $PITCH and other filters below are vars like "pitch -750" parec -d "$PHYSICAL_MIC" --raw --format=s16le --rate=44100 --channels=1 | \ sox -t raw -r 44100 -e signed -b 16 -c 1 - -t raw - \ $PITCH $OVERDRIVE $GAIN $REVERB $EQUALIZER $BASS $TREBLE $CHORUS $ECHO | \ pacat --raw --device="$VIRTUAL_MIC".monitor I can confirm that parec | sox works because I tested it with parec | sox | pacat and sox filters were correctly applied. Now I can't use wh40k virt mic on MS Teams: when I select MS Teams > Settings > Devices > Microphone: Monitor of wh40k I can't hear my voice from the Teams test call. Any clue on how could I troubleshoot this? My versions: - MS Teams 1.5.00.23861 (64-bit) - Linux Mint 21 Kernel - 6.8.0-40-generic - pipewire 1.2.7

I’m experiencing a recurring issue where YouTube videos in Firefox keep resetting to 50% volume on Fedora (with PipeWire). I normally set the volume to 100% (both in the YouTube player and in the KDE mixer), but occasionally, YouTube drops back down to 50% on its own. I’ve tried: - Switched to standard blocking - Verfied that media.default_volume is set to 1.0 (in about:config) - Clearing browser data and disabling all Firefox extensions - Switching to a brand-new Firefox profile - Checking KDE’s audio mixer (the volume shows 100% when I set YouTube to 100%, but moving the KDE slider doesn’t always reflect in YouTube’s internal slider) Despite these steps, the problem still persists. This happens most of the time when I have some YouTube Tabs open (but not visited them yet (with middle mouse click), close the browser and go to the videos. I haven't experienced this on Brave or LibreWolf and also not on another video platform like odysee. Also, if I reload the site it's back to 100%. (Firefox 133.0.3 from Fedora)
