I have been doing some research and it looks like my xrandr has some issues. The problem is I connect a HDMI monitor and it shows that is disconnected; somehow the port is not working properly. I'm using Manjaro. xrandr output: Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767 eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 380mm x 210mm 1920x1080 60.03*+ 48.01 1400x1050 59.98 1600x900 60.00 1280x1024 60.02 1280x960 60.00 1368x768 60.00 1280x720 60.00 1024x768 60.00 1024x576 60.00 960x540 60.00 800x600 60.32 56.25 864x486 60.00 640x480 59.94 720x405 60.00 640x360 60.00 DP1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) VGA1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) As you see, it show as disconnected but the HDMI is connected. Is there any way to solve this?

I have Ubuntu 14.04.3 with kernel 3.16.0-48 installed on mini-PC Gigabyte GB-BXBT-2807. The chipset also integrates audio controller Realtek ALC283. I've been struggling to have my audio play over HDMI, with no luck. First of all, I removed PulseAudio and reinstalled ALSA as was recommended in multiple articles on the web: % dpkg -l | grep alsa ii alsa-base 1.0.25+dfsg-0ubuntu4 ... ii alsa-utils 1.0.27.2-1ubuntu2 ...

I tried to run aplay -D for different devices marked as DEV=3 as listed above, but none of them worked. Also, it doesn't work in FireFox. Is there a special configuration to set audio play on HDMI? What else should I try?

A fresh Mint is installed, and volume control shows "no cards available for configuration"; it's an Asus NUC 14 Essential connected via HDMI to a SONY television.

I have an nvidia gtx 1050 running on debian 9. I have 2 external monitors, one through Display port and one through HDMI. Both monitors output the sound just fine, but only one at a time. Is there any way to combine sound for both digital outputs? I tried using Pulse audio preferences to add a virtual device, but that device is a bridger between the "Digital Ouput" (motherboard sound) and one of the HDMI outputs (whichever is currently enabled/active)

I'm running Garuda linux on my desktop and my computer has 2 HDMI ports and one of those comes from the NVIDIA 2070 super. The regular HDMI works all the time with no issues but the nvidia one just seems to stop working with no errors or anything. If the cable is plugged in on boot it will work if I'm in BIOS but after that the screen is frozen on the welcome to grub screen. I'm guessing this is a problem with my nvidia drivers. How do I trouble shoot?

I thought moving to another distro would help but nope, HDMI still does not work with debian 11. My best lead a post telling me to update my graphics driver but I don't know how to do that safely. Is this what I should do or is there an easier solution? I see that alot of people have asked the same question and I'm sorry to pile on to that but I don't really know what to do honestly. (No it is not the HDMI cable nor is it any combination of plugging the cable in and restarting the computer)

Oddly the sound cards seem to be HDMI so maybe that is the issue? This is an HP Envy x360 and it has worked perfectly other than this small problem. I would like to be able to play sound though and would greatly appreciate any help in solving this problem. Thanks!

I have a Beelink SER3 mini-pC running Debian 12, fully patched. This machine is based on the AMD Ryzen 7 3750H with Radeon Vega Mobile Gfx. The HDMI port is plugged into a Denon AVR receiver, and this receiver is plugged into a 4K TV. This works well. The X server starts up in 4K, and pulseaudio happily sends audio via the HDMI port, which the receiver can play through speakers. The problem is if the machine is turned on while the TV is off. In this case it doesn't detect any ouput; pulseaudio goes to a null-sink and even if I turn on the TV later I don't get a display. A quick reboot with the TV on and everything is OK again. Without the TV I see an extra line in the boot messages

kernel: [    4.095325] amdgpu 0000:04:00.0: [drm] Cannot find any crtc or sizes

That's pretty much the only difference in "amdgpu" boot messages from the kernel. Is there a way of forcing the kernel to believe there's a display connected at bootuo, even if there isn't? Or convincing pulseaudio to work (it just needs the AVR, not the TV) and the X server to detect when the TV is turned on?

I'm using Fedora 40. I alternately plug in my monitor (without speakers) and my home theater system to my laptop's single HDMI port. I would like to automatically direct sound output to the home theater system if it's plugged in, and otherwise use the internal speakers. As it is, sound output automatically switches to HDMI if it was previously set to do so, regardless of which device is connected. Is there something I could configure to remember the desired sound output per connected device, instead of treating all devices connected via HDMI the same? aplay -L lists different names when the different devices are connected, but wireplumber does not update its node properties from ALSA when hotplugging.

I have an HP Zenbook Power G9 with Ubuntu, which comes with an HDMI port. My issue is that this port does not work. When I plug the cable into it, nothing happens and the extra screen stays black. I just checked to be sure (it's a dual boot machine) and also Windows does not detect it. Screen and cable work, I tested them with a different laptop. They also work if I plug the HDMI cable into the USB-C port through and adapter. I have tried updating the NVidia drivers and Linux Kernel, but to no avail. Strangely, the HDMI port is not even listed by xrandr:

What could I try next?

I'm running Arch Linux on my laptop and have an external monitor connected via HDMI. I want to close the laptop lid while using the external monitor, but I want the laptop's internal speakers to keep working because I don’t have external speakers on the monitor. I’ve already configured my power management settings to prevent the system from suspending when the lid is closed. Specifically, I’ve edited the /etc/systemd/logind.conf file with the following settings:

HandleLidSwitch=ignore
HandleLidSwitchExternalPower=ignore

However, even after this, the laptop’s internal screen still turns off when I close the lid, which is not what I want. I’d like to only turn off the internal screen while keeping the speakers active and the system running as usual. I have also checked the power settings in KDE Plasma and set it to "Do nothing" when the lid is closed, but the issue persists. What am I missing or doing wrong? How can I close the lid and turn off the screen while keeping the internal speakers working when using an external monitor?

With X.org I was using /usr/bin/xrandr --off to switch HDMI display power off. However, I can't find how to do this with Weston?

**Setup** Headless single board computer (this one) which has an HDMI **in**put *(To clarify, this is a port which takes in HDMI like a monitor would. It will* **receive** *HDMI feed, not export it, like a computer normally would. Most computers don't have an HDMI-in port, so it's necessary to specify that this one does and that's what we're talking about.)* Android device with HDMI output **Goal** As soon as the HDMI output cable gets plugged into the headless computer, a script is triggered which records the video stream. When it's disconnected, another script is triggered (to process the recorded video). I haven't been able to nail down how to access an HDMI input programmatically, or how to edit the default behavior when one starts to receive input. I'm guessing that Linux will have a way to do this, but if there's a solution with Android, Orange Pi Droid, or OpenWRT, I'll take it. Thanks! (I've read some other posts, but none of them had conclusive answers. Here are some of them: Run a script on monitor connection/disconnection event Triggering a script when I plug in an HDMI in Raspberry Pi 4 Commands to run when Connecting HDMI )

I have a headless home server running Debian 12 without X.org. I might need to occasionally plug in a screen over HDMI to troubleshoot issues, however that doesn't work unless I reboot the machine first. When I do, the screen is detected just fine and hot plugging/unplugging works as well. What do I need to do to have this functionality readily available without installing X?

Sound wont play over HDMI,I tried all options from this list but no luck. Also my lap top has only 1 HDMI port, not sure what all these options come from.

When I connect to the television via HDMI, all I get on the screen is my desktop background. This is regardless of what is on my laptop screen. I am using Linux Mint cinnamon.

Since updating from Ubuntu 22.04 to 24.04, my [USB-C -> HDMI adapter](https://www.amazon.de/dp/B0C9MD3WHP) is not recognized anymore. I have tried to detect it with lsusb, lspci, usb-devices, dmesg ... whatever I do, plugging the adapter in does not change the output of any of these commands. It's as if nothing was plugged in at all. (Plugging in other USB devices, such as USB sticks, shows up in dmesg, for example.) I have reproduced this behavior on different computers using Ubuntu 24.04, with different USB-C ports. Interestingly, on an Android phone, the USB-C -> HDMI adapter is detected, but transmitting video is not possible (when setting USB to "Controlled by this device", I get the error message "Couldn't switch"). Still, the adapter worked a few days ago with a friend's phone (at a time where it already did not work anymore from Ubuntu). How would you go about diagnosing this problem?

Okay guys i lost all hope to solve this problem. I have a dell m4800 which supports 2 gpu's Intel and AMD m5100. i tried everything to get the AMD GPU to work but with no luck, the main problem is that the HDMI port is connected to the AMD GPU and i cant get it to work. here is my xrandr output : $xrandr --listproviders Providers: number : 2 Provider 0: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 4 associated providers: 0 name:modesetting Provider 1: id: 0xdd cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 6 outputs: 4 associated providers: 0 name:VERDE @ pci:0000:01:00.0* so i cant tell it sees the GPU but i cant use it: the out put for inxi -G: Graphics: Device-1: Intel 4th Gen Core Processor Integrated Graphics driver: i915 v: kernel Device-2: AMD Venus XT [Radeon HD 8870M / R9 M270X/M370X] driver: radeon v: kernel Display: x11 server: X.Org 1.20.8 driver: ati,modesetting,radeon unloaded: fbdev,vesa resolution: 1920x1080~60Hz OpenGL: renderer: Mesa DRI Intel HD Graphics 4600 (HSW GT2) v: 4.5 Mesa 20.1.2 i checked archwiki but unfortunately with no luck to solve the problem. any help would be great. thanks '''''''''''''''' Org X Server 1.20.8 X Protocol Version 11, Revision 0 [ 17707.015] Build Operating System: Linux 4.19.0-8-amd64 x86_64 Debian [ 17707.015] Current Operating System: SMP Debian 5.6.14-2 (2020-05-23) x86_64 [ 17707.015] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-5.6.0-2Debian-amd64 root=UUID=41ce03bf-3470-48db-92d9-0552d7f254ac ro quiet splash noautomount quiet [ 17707.015] Build Date: 31 March 2020 10:14:40AM [ 17707.015] xorg-server 2:1.20.8-2 (https://www.debian.org/support) [ 17707.015] Current version of pixman: 0.36.0 [ 17707.015] Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

**Introduktion:** I having a HDMI PHY SII9022A. I want to enable audio on that PHY. **Requriments:** I need to create a proper device tree for the SII9022A. https://www.kernel.org/doc/Documentation/devicetree/bindings/display/bridge/sil%2Csii9022.yaml According to this file, I need to activate audio-graph-card bindings and of course i2s. I have created my device tree. Notice that I have not using MCLK (Master Clock) because PLL can be used instead of MCLK. My linux kernel configuration looks like this. My device tree looks like this: hdmi-transmitter@39{ compatible = "sil,sii9022"; reg = ; iovcc-supply = ; cvcc12-supply = ; reset-gpios = ; interrupts = ; interrupt-parent = ; #sound-dai-cells = ; sil,i2s-data-lanes = ; /*clocks = ; clock-names = "mclk";*/ status = "okay"; ports{ #address-cells = ; #size-cells = ; port@0{ reg = ; sii9022_in:endpoint{ remote-endpoint = ; }; }; port@1{ reg = ; sii9022_out:endpoint{ remote-endpoint = ; }; }; port@3{ reg = ; sii9022_tx_endpoint:endpoint{ remote-endpoint = ; }; }; }; }; &i2s2{ pinctrl-names = "default", "sleep"; pinctrl-0 = ; pinctrl-1 = ; status = "okay"; /* USER CODE BEGIN i2s2 */ clocks = , , , ; clock-names = "pclk", "i2sclk", "x8k", "x11k"; i2s2_port:port{ i2s2_endpoint:endpoint{ remote-endpoint = ; dai-format = "i2s"; mclk-fs = ; }; }; /* USER CODE END i2s2 */ }; **Question:** As you can see, I'm using the dai-format = "i2s", but still, I'm getting this debug messages. drivers/gpu/drm/bridge/sii902x.c:577 [sii902x]sii902x_audio_hw_params =p "%s: Unsupported i2s format %u\n" drivers/gpu/drm/bridge/sii902x.c:560 [sii902x]sii902x_audio_hw_params =p "%s: I2S clock provider mode not supported\n" From this .c code: https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/bridge/sii902x.c static int sii902x_audio_hw_params(struct device *dev, void *data, struct hdmi_codec_daifmt *daifmt, struct hdmi_codec_params *params) { struct sii902x *sii902x = dev_get_drvdata(dev); u8 i2s_config_reg = SII902X_TPI_I2S_SD_DIRECTION_MSB_FIRST; u8 config_byte2_reg = (SII902X_TPI_AUDIO_INTERFACE_I2S | SII902X_TPI_AUDIO_MUTE_ENABLE | SII902X_TPI_AUDIO_CODING_PCM); u8 config_byte3_reg = 0; u8 infoframe_buf[HDMI_INFOFRAME_SIZE(AUDIO)]; unsigned long mclk_rate; int i, ret; if (daifmt->bit_clk_provider || daifmt->frame_clk_provider) { dev_dbg(dev, "%s: I2S clock provider mode not supported\n", __func__); fmt) { case HDMI_I2S: i2s_config_reg |= SII902X_TPI_I2S_FIRST_BIT_SHIFT_YES | SII902X_TPI_I2S_SD_JUSTIFY_LEFT; break; case HDMI_RIGHT_J: i2s_config_reg |= SII902X_TPI_I2S_SD_JUSTIFY_RIGHT; break; case HDMI_LEFT_J: i2s_config_reg |= SII902X_TPI_I2S_SD_JUSTIFY_LEFT; break; default: dev_dbg(dev, "%s: Unsupported i2s format %u\n", __func__, daifmt->fmt); <-------------------------------- return -EINVAL; } So how can I get the I2S clock prover mode a proper setup?

Good day everyone. My laptop has a RTX 4080 Nvidia dGPU with HDMI and DisplayPort directly connected to it. Video works perfectly, but I have no audio. I wonder if it’s fixable or just not supported with the open drivers. I use Tumbleweed, with Plasma (Wayland session). ~> aplay -l **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 3: HDMI 0 [GP01] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 9: HDMI 3 [HDMI 3] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: sofhdadsp [sof-hda-dsp], device 0: HDA Analog (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: sofhdadsp [sof-hda-dsp], device 3: HDMI1 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: sofhdadsp [sof-hda-dsp], device 4: HDMI2 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: sofhdadsp [sof-hda-dsp], device 5: HDMI3 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: sofhdadsp [sof-hda-dsp], device 31: HDA Analog Deep Buffer (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 If I use alsamixer or simply the KDE's settings, I can clearly see that I can either select the laptop's audio output, or my HDMI's.
