Can't get sound to work on new installation with ALSA.

Hi all,
I've been trying to get audio to work for the past few days to no avail.

The error I get in speaker test is:

~ >>> speaker-test -c2                                                                                              

speaker-test 1.1.4

Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1099:(snd_pcm_dmix_open) unable to open slave

Some info:

I tried adding:

$ cat /etc/modprobe.d/50-alsa.conf
options snd-hda-intel index=1,0

and then

$ cat /etc/modprobe.d/50-alsa.conf
options snd-hda-intel index=0,0

But they didn't work as well.

Heya,I just performed fresh install myself a few days ago and had issue with sound too.
Well, sort of, I first installed full gnome package and sound worked, then decided to go with LXDE where it didn't work, and after I couldn't make it to work went back to gnome again and the sound worked out of the box again...
I know it doesn't exactly fix your problem but there's that option if you want to try.

Your HDMI audio card is split into devices 3 and 7 of the card 0. ALSA, by default, plays back to the card hw:0,0 which doesn't exist in your case. Therefore try to figure out the correct device with

speaker-test -Dhw:0,3 -c2 #Or -Dhw:0,7

if you have the one that works, configure the default ALSA device to play back to in /etc/asound.conf or .asoundrc:

defaults.pcm.device = 3 #Or 7

Thank you V1del, unfortunately these aren't the answer.

They work in the command line, but none of them makes any sound. I tried this with 3 different cables and two different TV/monitors where the sound works fine with other equipment.

~ >>> speaker-test -Dhw:0,3 -c2

I'm lead to think that maybe there is some bug in the kernel driver or the ALSA regarding this ATI/AMD HDMI card.

Which card are we talking exactly? You did unmute/enable the outputs with alsamixer?

Gusar · 2017-10-29 18:28:18

Are you using the amdgpu kernel driver? That one doesn't have HDMI audio support. It might with kernel 4.15 if Linus accepts AMD's new display code. Until then, you'll need to use a patched kernel. This might do the trick: https://aur.archlinux.org/packages/linux-4.13.y-dc

V1del:
The card is the 00:01.1 Audio device [0403]: Advanced Micro Devices, Inc. [AMD/ATI] Kabini HDMI/DP Audio [1002:9840]

It's an integrated X3000 (Gen3) APU.

But yes I unmounted all the outputs. Although the outputs that show up in alsamixer are just 2 S/PDIF.

Gusar:
First I tried to install AMDGPU-PRO (according to the arch page it had HDMI audio output) but it didn't work. Although I'm not sure the system was using the AMDGPU-PRO driver, I just rebooted (according to the guide is enough).

I'm now waiting (for some hours) for the compilation of the linux-amd-staging-drm-next-git kernel to finish. Let's see if this finally solves the issue.

jbssm · 2017-10-30 01:07:52

Ok, the kernel finished compiling and after reboot the system freezes since it can't access the root system dir. I think this is because I'm using BTRFS and bcache and this kernel doesn't have support for at least one of those.

jbssm · 2017-10-30 19:48:39

Ok, after fiddling around there was a bug in the staging kernel for AMD that I had to solve by putting the block before autodetect in mkinitcpio

After that it boots up fine but... yet again, no sound trough the HDMI audio.

I'm starting to wonder why people praise so much AMD for linux... sincerely, with NVIDIA, all this just works and it works well.

All in all still no sound and a lot of bugs. Any ideas?

The X3000 apu appears to be rather new and intended for server use.
Is the firmware uptodate ?

Try with linux-amd-staging, mesa-git , llvm-svn and xf86-video-amdgpu-git .
Building all those will take a long time even on fast systems, you can find them in lordheavy's unofficial mesa-git repo .
I suggest reading https://bbs.archlinux.org/viewtopic.php?id=212819 before you start using it (atleast my opening post in it).
