I've spent 2 hours on this and still can't figure this out. It's driving me insane. Please save my sanity. When I press mute, the pnmixer control in the top right shows that I've pressed mute, but the sound is not muted. A graphic also appears on my screen with a volume bar to show that the volume has been muted. When I press mute again, the pnmixer control shows that I have pressed the key, and **three** graphics appear on my screen in a row to show that I've pressed it. This doesn't make sense. No change in sound. With the volume up and volume down keys, the graphic changes accordingly but again no change in sound. I've tried editing rf.xml with the following: amixer set -q Master,0 5%+ amixer set -q Master,0 5%- amixer set -q Master,0 toggle I used xev to get the names of the key bindings. After reconfiguring or restarting openbox, or restarting my computer, this change in the script had no effect at all. Btw, uname -a gives me: Linux KGBXCrunch 3.2.0-4-amd64 #1 SMP Debian 3.2.35-2 x86_64 GNU/Linux

I've just recycled and old Asus T100 transformer by installing a Spiral XFCE linux distro. The goal is to use it for videos. It works mostly fine, but I still have trouble for volume setting : The volume keys on the tablet do not work at all (even though it seems to have been working out of the box for some people cf http://www.jfwhome.com/2016/01/04/latest-steps-to-install-ubuntu-on-the-asus-t100ta/ ) If anybody has any idea how to fix this, it would be great ! If there is no solution to that, a way to have the keyboard volume keys work without having to press the "fn" key would be great too. I found a few ways to tweak the setting, mostly related to fnlock_default in /sys/module/asus_wmi/parameters (cf https://forums.linuxmint.com/viewtopic.php?p=2247849#p2247849 ) but none of them seems to be working. Any idea ?

Sometimes I listen to some audio which has its base/lower-frequencies too weak and its mid-range higher, or the other way around. When that happens, I find myself turning the volume up, then down, repeatedly as different frequencies are either too loud or barely audible. Now, if I have the entire piece of audio saved in some file, I can use Audacity or another such tool to do some filtering which would take care of this (I guess, I'm kind of a newbie on that). But for whatever audio file or stream I'm listening to casually, in a web browser or whatever other app - that's not an option. My question: On a typical Linux desktop enviornment, say Debian or Devuan, can I somehow control the volume level by frequency range? i.e. have something like an equalizer ?

Not sure if the topic is too audio-specific to be posted here, if so then do tell and I'd appreciate suggestions on proper forums. My LP recording setup is through an M-audio 2496 card on linux running jack, using a command line script to capture. I use the hardware input to capture and set the recording level using alsamixer; My usual capture level has been -3 dB for years. These days I'm testing a new phono preamp that has an higher output level than my other units so I lowered the capture level to -6dB but ran into clipping issues. Investigating this problem, it turns out that setting the capture level below -3 dB on hardware channels "H/W Multi" (left) and "H/W Multi 1" (right) clips the signal ! Perhaps some pics would help illustrate the phenomenon. Below are shots of the same high modulation passage of an LP record at different capture levels in alsamixer. Note that except for the 0 dB test, there were no Xruns or overruns during the recording process. At 0 dB I get overload peaks as can be expected; at -3 dB things seem ok like my usual setup; Note the recorded amplitude level. But as you can see, lowering capture level further not only reduces overall recorded amplitude but clips the peaks, even if they reach a lower amplitude than the recording at -3 dB. I always assumed the alsamixer capture level worked as an equivalent of the "recording level" on the cassette decks of my youth, e.g. simply attenuated the signal. Now it seems it both attenuates and limits somehow.... I'm confused! Please help me better understand what's going on here and thanks in advance for any insights. -Joe

I'm using qpwgraph as a GUI to manage audio streams, but I don't see how to control the volume interactively through the GUI itself. Example: I can send audio from a browser to both my headphones and to a browser instance of Discord. To be able to control the headphone and Discord volumes independently, I can create a virtual sink with output to Discord, leaving the default sink with output to my headphones, and then use wpctl set-volume on the command line to the set the volumes. I would like to be able to set the volume interactively through, say, a GUI slider rather than have to use the command line. Is this possible with qwpgraph? If not, is an alternative to qpwgraph that allow for GUI management of streams AND their volume?

**Issue** I run Linux Mint on my Satellite P55W-C laptop, and what I've observed was that the Bluetooth volume for my ear buds starts at 80% whenever I connect to this Bluetooth device after closing and reopening the laptop. Even after I adjust it to 30-40% it goes back to 80% after I restart the laptop. This kind of problem persisted across multiple distros like Debian, Ubuntu, Arch which I have used in the past on the same laptop. This issue did not occur in the Windows OS I dual boot in it. **Specifications** _Laptop:_ OS: Linux Mint 21.3 x86_64 Host: Satellite P55W-C PSPVJU-00T016B Kernel: 5.15.0-112-generic Resolution: 1920x1080 DE: Cinnamon 6.0.4 WM: Mutter (Muffin) Terminal: gnome-terminal _Earbuds:_ OnePlus Nord Buds 2 **Question** Is there a way to enable saving the Bluetooth volume levels of Bluetooth devices across multiple sessions?

One time when I rebooted my computer, suddenly, the audio won't change and the audio settings only say No output or input devices found. I have replaced pulseaudio with pipewire, but it stilled worked after a reboot following the replacement. When using kmix and rebooting again, the audio can be changed, but the audio applet in KDE Plasma shows the same message. I can still hear audio, but I need to manually change it with programs like alsamixer or kmix. Also, I tried making the same conditions on Virtualbox with pipewire instead of pulseaudio, and the audio worked in the virtual machine. How can I fix plasma-pa's audio problem? My Linux distribution is Debian Sid. Output of pactl info:

Connection failure: Invalid server
pa_context_connect() failed: Invalid server

Version of packages:

plasma-pa: 4:5.27.10-1+b2
pipewire: 1.0.5-1+b1
pipewire-pulse: 1.0.5-1+b1

I can change the master volume with these commands (from the command line), and it affects all applications, but how do I change the volume for just one application (XMMS for example)? amixer -q set Master toggle # or pactl set-sink-mute 0 toggle amixer -q sset Master 5%+ unmute # or pactl set-sink-volume 0 -- -5% amixer -q sset Master 5%- unmute # or pactl set-sink-volume 0 -- +5% pacmd dump # is interesting, and there are GUI applications that can do this: gnome-control-center sound, pavucontrol

In "Settings->Window Manager" I can customize keyboard shortcuts for actions such as window tiling or maximizing and minimizing windows. There is no option to control the volume with keyboard, though. It is possible in Cinnamon which has a similar control panel for keys but I don't know how to do it in Xfce.

*I guess this is sort-of a software recommendation question, but if I post it there I think even less people will be familiar with this specific setup (5.1 surround, Debian 12, KDE and PipeWire)* I recently upgraded from PulseAudio to PipeWire which enabled 5.1 on my setup surprisingly. I got a USB SoundBlaster that feeds *Digital Surround 5.1 (IEC958/AC3)* (compressed 6-channel audio through TOSLINK optical) into my sound system. For the purposes of the question, the OS sees this as 6 individual channels, and I'm able to play for example multi-channel FLAC files in VLC, or even Firefox. The built-in KDE sound applet in the System Tray as well as the System Settings > Sound allow me to individually control the volume of each sound channel, however only the applet shows a VU meter and it's in mono/stereo. **Is there a program / plugin that can show the individual volumes of each sound channel, sort of like Audacity has its "Mixer Board" which displays the VU level of each individual track.** I would be OK with any full fledged Gtk/Qt app, a KDE add-on, even a cli terminal app that shows the VU levels. Less preferable but even VLC add-on would at least do the job. I recently started making multitrack mixes of different songs, and my own music I play on guitar into 5.1 mixes, but they are hard to balance just by listening, I want something visual as it plays. (Audacity shows these visually, but cannot output 5.1 audio during the mixing, only after it has been exported to FLAC and played with a different app like VLC). I tried Easy Effects which is an amazing new app made for PipeWire, however they do not support multi-channel and do not plan on doing it as it would require a total rewrite (according to their Git/issues history).

My setup: Void Linux, xorg, dwm + dmenu + st, DAS keyboard. I can probably figure out how to bind some "normal" keys for volume control, but I really like this big round knob on my keyboard :). So, how to make the volume control to work from my keyboard?

The right audio output is not working in Pop OS 22.04 Hello there, I did many attempts through these links and it's still not working.: https://www.reddit.com/r/pop_os/comments/uem5uk/unmet_dependencies_pulseaudio_pop_os_2204/ https://support.system76.com/ What do I need to do to get my right audio output working on Pop OS 22.04? I am using an Intel NUC i5 10th Generation with my Sceptre TV.

I've upgraded from Linux Mint 19.3 with kernel 5.4 to Linux Mint 21.1 with kernel 5.15. Now I cannot change the sound volume (using the sound icon in the task bar) of my speakers which are connected via my external USB sound card/DAC "Behringer UCA222" anymore. This sound card is over 10 years old and known to work very well with Linux. **So the problem is, that while I can hear sound and I can also mute it, I cannot change the volume of it.** What I've tried: - Installing pavucontrol and tried all possible profiles and played around with every knob but no success - Installing Kernel 5.19, with no success.

Below is pavucontrol GUI. As you can see, volume is 100%. I can use the knob of my Roccat external keyboard, to change it to any value between 0% and 100%. Now I do the following - set it to something lower than 100%, say 69%, - suspend the system via systemctl suspend - wake the system up At this point, the keyboard knob will allow me to reduce the volume below 69%, ***but not increase it above 69%***. I can pull up the volume to 100% using pavucontrol, at which point the knob can again span the whole 0-100% range. Why is that the case? And how can I fix this?

I have two Bluetooth devices: a speaker SoundCore Boost and headphones EDIFIER W830BT. When I'm trying to change the volume on headphones using system volume settings it does work. Headphones also have buttons on them for controlling volume and those buttons also work (they change system volume in Linux). But on a Bluetooth speaker changing volume in Linux doesn't affect the actual volume. On the other hand, using volume buttons on the speaker does change the system volume in Linux (and the volume level bar in Linux changes as expected when I use the device's buttons). Also, when I mute system volume in Linux it does affect the speaker (sound mutes). Summarizing - Bluetooth devices work, sound plays, I can change volumes using devices' buttons but only the speaker volume can't be controlled via Linux system volume (except muting). I removed and paired again the speaker but that didn't help. For both devices, Output Device configuration is set to Hight Fidelity Playback (A2DP Sink). The same speaker works well on macOS (changing system volume affects the speaker volume).

Any ideas on how to solve the problem? --- Edit 1: I booted live LTS version with an older kernel

$ neofetch
OS: Pop!_OS 20.04 LTS x86_64
Kernel: 5.13.0-7620-generic

And it turned out that there's no issue with that version - system sound control affects the volume of my Bluetooth speaker as expected. I also booted the live version of my current system (to confirm that there's no issue with my installed version) and the issue with volume control was present. So my guess is that kernel 5.15.8-76051508-generic does something with Bluetooth and sound control differently than 5.13.0-7620-generic. --- Edit 2: I downgraded the kernel version to 5.13.0. https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.13/ I downloaded 4 files and installed them

$ ls
linux-headers-xxx_all.deb
linux-headers-xxx-generic_xxx.deb
linux-image-usigned-xxx-generic_xxx.deb
linux-modules-xxx-generic_xxx.deb

$ sudo dpkg -i *.deb

Pop!_OS doesn't have GRUB and uses kernelstub https://github.com/isantop/kernelstub/blob/master/README.md I changed the kernel version using the following command (where xxx is the desired kernel version)

$ sudo kernelstub -v -k /boot/vmlinuz-xxx-generic -i /boot/initrd.img-xxx-generic

After the reboot, I see that I'm using kernel 5.13.0-051300-generic but that doesn't solve the problem with volume control.

$ uname -r
5.13.0-051300-generic

So my guess is that Pop!_OS changed something between 20.04 LTS and 21.10 that broke proper volume control in my Bluetooth speaker and it's not the kernel's fault.

In older versions I used to comment out osd.show(percent) in the functions increaseVolume and decreaseVolume in the file /usr/share/plasma/plasmoids/org.kde.plasma.volume/contents/ui/main.qml (blog source ). But that file does not exist anymore in Plasma 5.13. Is there an other way to disable it?

I'm frequently changing the audio setup of my laptop (sometimes using the built-in jack port, sometimes nothing at all, sometimes using USB headphones, sometimes using the jack port in the dock of my laptop). I'd like to have keyboard shortcuts to lower or increase volume *for all outputs at once*, so it works no matter which audio output is currently active. What's the easiest way to achieve this? I also see that in pavucontrol, I can go above 100%, which is sometimes practical, so if the command was also able to do this, that'd be great. I'm running Debian Testing, kernel 4.9.0-3-amd64, and pulseaudio 10.0.

I run Debian 9 with LXQt what is completely fine. However, attached USB-volumes are not getting displayed in the PCManFM-Qt sidebar in category Devices intended for that (see screenshot). Which package is responsible for that? I activated all three necessary options in Preferences -> Volume, but the drives still don't appear in the sidebar. Ironically the taskbar-widget shows the drives and I can easily open them in PCManFM-Qt by clicking on the widget. However they are never displayed in the sidebar while the category Devices remains completely empty. During common workflows that is a bit uncomfortable... ---------- **Screenshot of the issue:** **Screenshot of the working taskbar widget:** PCManFM-Qt correctly" class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> Again, clicking on the taskbar widget the device gets opened in PCManFM-Qt without any problems. Only displaying its existence in the sidebar does not work.

Normally, after a recent fresh install of Linux Mint 19.3 x64 MATE on an Acer Aspire E15 laptop, media keys (using Fn+arrow keys on the built-in keyboard, or dedicated keys on an external keyboard) work fine for changing the volume: A modal pops up showing the current volume level, and disappears after a moment of not adjusting the volume. Also, the default volume control tray icon affects the same volume level when I drag the slider. Now, sometimes we'll plug in an HDMI device that has built-in speakers, and want the audio to go through the speakers. Often the software audio source (browser, for example) is already open, and the only way I've found to switch its output to HDMI _without_ having to restart the browser, is to go into the default Sounds applet: ...and set the analog output to Off, and the HDMI output to HDMI. The problem is, once I've done this (or the other way around—started with HDMI and then switched back to analog stereo) the media keys no longer have an effect on the volume level. (But they _do_ still make a popup showing a level changing...it just doesn't actually affect what's heard!) Also, the volume control tray applet no longer has an effect on what's heard. The slider still visually works, but strangely, seems to have become independent from the popup that the media keys produce. Then, often the tray applet will simply disappear entirely (crashed, I guess.) At that point the only (GUI-based) way to change the volume is to open the Sounds applet pictured above and adjust it from the slider there. My main question is, how can I keep them working after switching audio outputs as described? Or, if there happens to be a way to avoid this problem by using a different method than described for forcing an audio output change, that would be a welcome answer too.

I'm on Arch right now, but I had the same problem (although slightly less often) on openSUSE Tumbleweed. Basically, whenever I enter or leave a breakout room in Zoom, and sometimes randomly while I'm sitting in a room that's not a breakout room, Zoom gets muted and I have to go to my sound settings to bring the volume back up. My job is being done over Zoom right now and I have to switch in and out of breakout rooms a lot, so it's getting really inconvenient. I've tried looking around online, and from what I can tell, Zoom will periodically swap input sinks, and that's when it gets muted (when I run pacmd list-sink-inputs, the index of Zoom changes, at least), and I've seen fixes for if a particular input sink gets muted, but not if the same application keeps muting (or nearly muting) over changing input sinks. Any advice or ideas on how to fix greatly appreciated. Edit: I've dug a little deeper, and it looks like the configuration file for pulse audio that defines the default input sink volumes for different processes is being changed automatically when Zoom runs, I've tried changing back with pa_volume, but it keeps changing it back. I was hoping to try to set up a script to watch for changes in that file and change it back when need be, but I haven't actually been able to detect changes using inotifywait so I'm stumped again.
