 |
|
Hi guys,
It's a fresh install and pulseaudio can't find my sound card. Looks like my Realtek chip is set to Intel HD Audio driver and kernel module, which I think is incorrect.
Hardware:
+ AMD Ryzen 5 5600G
+ MSI B450 Mortar Max
+ Realtek® ALC892/ALC897 Codec
| Code: | $ uname -a
Linux orion 5.10.76-gentoo-r1 #1 SMP Mon Dec 13 04:02:21 -00 2021 x86_64 AMD Ryzen 5 5600G with Radeon Graphics AuthenticAMD GNU/Linux

Steps to check:
+ Is your user in audio group?
| Code: | $ groups
//Should output audio
|
If not:
| Code: | | # useradd -a -G audio my_username |
+ Check the kernel you compiled. In my case, I was not using the right version. I needed to sanitize, then recompile. Also,

megalodon,
Your kernel support is missing as you don't have any Control or pcm devices in
| Code: | ls -l /dev/snd

snd-hda-intel and its codecs must either be all <M> or all <*> a mix of built in and modules fails by design.
-- edit --
I've just seen your .config.
| Code: | CONFIG_SND_HDA=m
CONFIG_SND_HDA_CODEC_REALTEK=m |
That looks good.
Are you running the kernel you think you are?
What is the date and time in
That's the build date/time of the runining kernel. If you have made a newer one, its not being used.

Note:
As well observed by @NeddySeagoon, I was not using the kernel I thought, so I sanitized the kernel sources, then build it again, and things changed.

NeddySeagoon,
this is the new scenario:

megalodon,
You have two sound cards, one on the video card that drives HDMI/DP sound to your display and one on the motherboard that drives your analogue output.
From /proc/asound/devices, your video card is the default output card.
Which card do you want to use by default?
What does show?
Pulseaudio is a wrapper around alsa. I don't use it but being a wrapper it can't work until the thing it wraps works.

Is your normal user in the audio group?
Only root and audio group members have access to the sound hardware.
| Code: | $ ls /dev/snd -l

No, shame on me 
I think this was the last step
| Code: | | # useradd -a -G audio my_username |

I want to use the analog output, which is now selected by default.
Now it show a dozen of controllers, and is working great as far as I tested.
Thanks man, you deserve a medal  |
