No HDMI Audio #31

Closed jonrichards closed 6 years ago

jonrichards commented 7 years ago

I really appreciate you putting this repo together, thank you. I'm running 17.04 with Vega 64. pavucontrol shows all HDMI audio as unplugged.

Any thoughts on what may be the issue or anything I can try?

M-Bab commented 7 years ago

I am sorry to say that but it looks like you did everything right and it still doesn't work. Did you switch through the HDMI outputs to see if it works anyway (maybe plugin detection doesn't work)? Could you do any cross-check (e.g. with Windows) to ensure the HDMI sound of the GPU and monitor pair works in principle? You can use the <> button on https://github.com/M-Bab/linux-kernel-amdgpu-binaries/commits/master to download older kernels (maybe try 4.11.12 and 4.12.14) to see if this helps. Finally you can look through the logs and try to find some hints on the problem.

jonrichards commented 7 years ago

I have tried all of the outputs with the same result. I do know it does work though, as I had it working with this setup on a previous install. It might be that this time I installed the amdgpu-pro drivers first before switching to amdgpu. I don't think plugin detection is working though, as if I unplug anything I have to reboot to have it recognized.

Do you have any specific logs you recommend that I should check?

M-Bab commented 7 years ago

Did you fully remove the amdgpu-pro driver? It is important that the pro driver is purged otherwise this kernel can't work properly.

Can you post the outputs of: "dmesg | grep amdgpu" and "lsmod | grep amdgpu"

DarkFoss commented 7 years ago

@jonrichards You might want to run through your mesa install with dpkg or apt-cache policy and make sure everything related was fully installed. From what you posted your mesa-va-drivers is still stock Ubuntu but the rest show padoka. Check your dpkg log for installation errors during the upgrade. A purge of mesa-va-drivers and reinstalling might help if you see any half-configured messages. I'm not saying it's directly related but nice to rule out.

@M-Bab I think I got it all removed correctly:

@DarkFoss I did try purging and re-installing mesa-va-drivers, but it doesn't look like it's pulling from padoka.

~$ apt-cache policy mesa-va-drivers
mesa-va-drivers:
  Installed: 17.0.7-0ubuntu0.17.04.1
  Candidate: 17.0.7-0ubuntu0.17.04.1

However, looking at https://launchpad.net/~paulo-miguel-dias/+archive/ubuntu/mesa/+sourcepub/8353873/+listing-archive-extra I'm not seeing it listed there. Are you sure it's part of the padoka packages?

M-Bab commented 7 years ago

This is odd. It looks like it should (except for DarkFoss' valid comment). But usually it should update all of the mesa package if you add the apt repo - either padoka or oibaf.

Did you test 4.11.12 already? Because 4.12 and 4.13 fight with some regressions that did not exit in the 4.11 kernel.

piet8stevens commented 7 years ago

I have also been a grateful user of these custom kernels. I have now found I can play audio over hdmi through my Radeon HD 7700/7800 with the standard 4.13.0-generic kernel on Ubuntu 17.10. What I needed to do was to enable 2 screens in settings/devices/displays - set to 'join displays'. In my case, a Panasonic screen showed up (I only have 1 screen connected to my desktop). When I do that, sound over hdmi/displayport works with the standard kernel. I never tried this on 17.04 so not sure it was the same there. Even with your 4.13.6+ kernel, I get no sound if I only enable the one single screen.

piet8stevens commented 6 years ago

I am not sure how the 4.13.6+ kernel generated sound as per my above comment - I have had to go back to your custom kernels in order to have sound.

One thing I noticed with the custom kernel: if Ubuntu publishes a kernel upgrade, and I install it (but keep using your custom kernel), then my sound on the custom kernel still disappears and I have to reinstall the custom kernel (dpkg).

M-Bab commented 6 years ago

Thats an odd case I already experienced before. When you start a "normal" kernel right after a kernel with DC (warm reboot) it still has HDMI sound sometimes. No idea how this works at all. The custom kernel should NOT disappear on Ubuntu kernel updates. Are you sure grub boots the right kernel?

piet8stevens commented 6 years ago

Martin, the sound disappears even when I do not reboot. Next time it disappears, I will try to document it in detail and post here.

Thank you,

Piet

Can you recheck with 4.17?

piet8stevens commented 6 years ago

Well, this is a tough one to check as it is intermittent. Am on 4.17 and will keep an eye on it. For sure, under 4.16.12+, this issue still happened. uname -r 4.17.2amdgpu.ubuntu.18.06.19+

Thank you for your work!

piet make sure to set in your grub amdgpu.dc=1 amdgpu.audio=1 even though the DC code was for vega's its caused muted audio on my system where the hdmi fails. It seems the hdmi audio is entrenched with thre vega code

Thx. Will test and report back. Your efforts and M-Bab's are much appreciated.

@tekcomm - I already had amdgpu.dc=1 in grub. Added amdgpu.dc=1. Will see whether I still intermittently lose my sound. So far, so good. I guess there is still one thing I do not understand: why does amdgpu audio still not work with the generic kernel that comes with ubuntu?

Again lost sound. Still not sure why - cannot remember having made any changes. No problem after reboot.

Piet, can you please send me the out put of this script. https://gist.github.com/craftyjon/902247 amdgpu.dc=1 and amdgpu.audio=1 in /etc/default/grub

@tekcomm Thank you for all your help. Output of the script is http://www.alsa-project.org/db/?f=07ec5e3fe17a31d1bbf36e671a1b04c0d320582c and also attached. alsa-info 20180703.txt

Finally, I can confirm that amdgpu.dc=1 and amdgpu.audio=1 are in my /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.dc=1 amdgpu.audio=1"

Note: the output of the script was generated when sound worked again after reboot. Next time when I lose sound, I will also run the script.

And this is the output after having lost sound: http://www.alsa-project.org/db/?f=ab67667e699bb5ef98ac9b88a5c66bc0c86aa770

Can you please try this, I had a similar problem with paulo's ppa ppa-purge it and switch to the https://launchpad.net/~oibaf Another more serious problem that affects us all is the erratic behavior I have had with the main repositories failing and even I did not notice, till everything turned black. Try also switching from the main repo to a local mirror.

piet8stevens commented 6 years ago

Sorry about the delay. Have had very busy weeks. Will only be able to test in about 10 days' time.

M-Bab commented 6 years ago

Should be resolved. Close until there are contradicting comments.

piet8stevens commented 6 years ago

I am now on 4.18.8 (uname -r). I installed the ubuntu kernel. Sound is there originally and still disappears after some time. Sound comes back after reboot. I do need to switch from joint display to 1 display and back for the sound to re-appear.

piet8stevens commented 5 years ago

Maybe I found a solution: I added my user to the audio group. Now, I no longer seem to be losing my sound..
