Sound conf not properly loaded at boot

English Install/Boot/Login
#1

Hi,

Here is the thing:

  1. After booting, the sound doesn’t work properly and makes the same noise than old TVs without a program
  2. I found a temporary fix that always work: open YaST > Sound > Uninstall all sound cards, then use Edit and quick install for each of them to get the sound back (+ Apply which will save the changes).

Hereafter is the diff of lsmod (diff lsmod_file_after lsmod_file_before):

As you can see there are a few differences like:

  • snd_hda_intel 42034 4
  • snd 91489 17 snd_hda_codec_ca0132,snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_seq,snd_timer,snd_seq_device

(which are the new values).
I forgot how to change the modules loaded at boot and will start investigating on that for now. In the mean time, if anyone has an idea or can create an OpenSuse ticket (because there is clearly a bug) to get this issue fixed, that’d be great.

A few more information:

Also, if anyone knows 1) how to script step 2 that I described before and 2) get it loaded before login, that would be a fine fix to me. 1) only would be already really helpful.

I’ll keep investigating on that.

Do you have any odd repos active? Maybe you are pulling in experimental code from some where.

Report in Bugzilla
https://en.opensuse.org/Bugzilla

Give as much info as you can above what you provided here ie openSUSE ver update that broke things or is this from a new install?

#3

Now I have a few more repos than the default ones but this problem occurs immediately after installing the system.
The install process ends up with sound configuration, so it works once the installation is over but after a reboot, the sound will not work anymore and I have to delete/reinstall the sound cards as described before.
Will report the bug soon…

Do you know which extra useful information (commands to run) I could add to the ticket? I would start with:
uname -a
lsmod (after)
“diff of lsmod results”, provided in my first post
content of /etc/module/50-sound.conf
pacmd list-card (eventually since I have two sound cards)

#4

Might look at this blog post: PulseAudio and Selecting the Proper Sound Card Configuration - Blogs - openSUSE Forums

Thank You,
