How to output audio via HDMI if EDID of my TV is not working?

https://wiki.archlinux.org/title/Kernel … s_and_EDID
According to the page above, I can force my GPU to output 1080p to my TV which EDID does not work. However, there is still no audio output to the HDMI, is there any way to solve it?

I can force my GPU to output 1080p

stands a chance that you're driving output or cable out of spec and there's no bandwidth left for the audio (but it would work at lower resolutions)
If that's not it, you need to elaborate on the sound stack, for starters

aplay -L
amixer
pactl list cards
pactl list sinks

So I need to add radeon.audio=1 in the kernel parameter?
I didn't need to do this if I forced using another LCD's EDID binary file.

Re: How to output audio via HDMI if EDID of my TV is not working?

You need to test whether you can hear something when explicitly directing the audio output to the HDMI.
You're currently playing on the PCH by default and we need to know whether this is just a pipewire/pulseaudio doesn't properly™ redirect audio thing.

You need to test whether you can hear something when explicitly directing the audio output to the HDMI.
You're currently playing on the PCH by default and we need to know whether this is just a pipewire/pulseaudio doesn't properly™ redirect audio thing.

I've tried aplay -l and other stuff below, none of them worked.
I also tried to play videos with MPV player, and tried to output the audio to certain device, but it didn't work either.

In the past, I copied another moniter's EDID binary to my htpc, and forced to use it in kernel parameter, and the sound did output successfully, although it only output the left channel to my both speaker (left and right) of TV.

https://bbs.archlinux.org/viewtopic.php?id=57855

copy and pasting the blue boxes in the wiki there won't work for pretty much sure.

I copied another moniter's EDID binary

1. Why do you have to copy the EDID? Is there an adapter involved?

Re: How to output audio via HDMI if EDID of my TV is not working?

I didn't just copy and paste them to my terminal, I did look up the devices in aplay -l.

1. Because it didn't output anything to my TV if I didn't copy another EDID binary for it in the past.
2. It didn't in the past, but it does now, that's why I am trying not to copy another EDID to do it, however, after I force to use my custom EDID binary this time, it returns lower resolution to me.

It's pain in the ass if the EDID of TV is broken.

Good but that still doesn't indicate what kind of error you actually received, nor allows us to verify the correct procedure.

Please clarify this: do you say that if you drive the output at a lower resolution, you do indeed get an audio output via HDMI?

No, I mean if I didn't force to use my custom EDID binary, there was nothing output to my TV, but it does output at lower resolution today with my fresh install, I'm surprised, but no sound.
With my custom EDID, it output graphic at 1080p and sound, although it only output the left channel to my both speaker on my TV, but this method displays at 800*600 today with my fresh install.

Re: How to output audio via HDMI if EDID of my TV is not working?

Can you please post an Xorg log w/ and w/o your custom EDID?
800x600 doesn't sound like any reasonable EDID is applied, VESA alone should™ get you XGA (1024x768)

Also for the 3rd time

You can also try

xrandr --output HDMI-A-0 --set audio on # replace the output name

but I'm not optimistic that this is the cause here.

I'm using Gnome Wayland, but I will try it on Gnome Xorg if I can use the TV.
I can't find any equivalent method on Gnome Wayland.

After switching to Plasma desktop environment, all this shits are gone. It is a Gnome problem.
I've also tested pipewire on Plasma, it works as expected.
Which part of Gnome could cause this issue? Maybe I can report to them?

Re: How to output audio via HDMI if EDID of my TV is not working?

Shouldn't really be possible to be caused by that, unless the fact gnome has native pipewire integration breaks compared to "just" pulseaudio on plasma's side.

Things like potentially wayland/xorg I'd think more likely, did you use Wayland on GNOME and now Xorg on Plasma?

I use Wayland on both side, and pipewire on both side too, I'm sure that PulseAudio has been removed by me.
On Plasma Wayland, the left audio channel is sent to left speaker, right audio channel is sent to right speaker.
On Gnome (Xorg/Wayland), the left audio channel is sent to both speakers, I can't hear the right channel, it happened to PulseAudio too in the past, it has troubled me for years.

Re: How to output audio via HDMI if EDID of my TV is not working?

Plasma will use the pulse api to talk to pipewire while gnome will use pipewire's own api, the differences should™ be transparent to the end-user but maybe they aren't (and this really shouldn't matter with regards to where an established stream ultimately lands).

FWIW if you want to properly retest this on gnome. Post during working playback (in plasma) 

sudo fuser -v /dev/snd/*
pactl list sinks
pactl list sink-inputs

repost that same from not working gnome. If the outputs generally match we will indeed have a gnome problem. In which case I'm suspecting an issue with how the compositor sets up the monitors, so component wise my guess would be on mutter.

Edit: Seeing this added information, GNOME wants to maintain it's own volume database, double check the exact volumes/balances for both the end device and lone streams in it's audio settings (... plasma generally leaves volume handling to whatever pipewire does by default)

I will try it 3 days later, I can not occupy the TV now.

Why are they doing that.........

Don't really know why and maybe this changed with the pipewire integration, definitely was (... and I'd assume still is) the case with pulseaudio

I remembered several years ago, there was no such issue on Gnome, but one day it just happened.
When did they change it?

Re: How to output audio via HDMI if EDID of my TV is not working?

I'm not fiinding a reference to a pipewire change so maybe I just thought that was the case, checking https://gitlab.gnome.org/GNOME/gnome-co … nels/sound still just shows references to pulse, so the situation is likely the same. "Just happened" could've also been a change in kernel detection or so, and you might just need to fix the general volume situation. But that's speculation until you post these outputs during an attempt to play back.

Re: How to output audio via HDMI if EDID of my TV is not working?

Hi guys, it really isn't Gnome's fault, because I turn on my TV and PC today, and there is no right channel output to my TV, both of my speakers are left channel. However, I have found a way to make it work.

    1. I change my custom EDID(edid.bin) to bult-in EDID(1920x1080.bin).

    2. I change it(1920x1080.bin) back to my custom EDID(edid.bin).

    3. it works for no reason........Is it a kernel bug?

How stupid is this bug! It has troubled me for years!
