Hi,

I am having problems getting audio working on my computer:

00:1f.3 Audio device: Intel Corporation Device f1c8

I did an internet search that said that I would need 5.13 or later to
have support for this device.

The above is Cometlake-H, and it pretty much depends on the machine
configuration.

openSUSE 15.3 kernel 5.3.18-59.19-default says:

snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC233: line_outs=1 (0x1b/0x0/0x0/0x0/0x0) type:line
snd_hda_codec_realtek hdaudioC0D0:    speaker_outs=0 (0x0/0x0/0x0/0x0/0x0)
snd_hda_codec_realtek hdaudioC0D0:    hp_outs=1 (0x21/0x0/0x0/0x0/0x0)
snd_hda_codec_realtek hdaudioC0D0:    mono: mono_out=0x0
snd_hda_codec_realtek hdaudioC0D0:    inputs:
snd_hda_codec_realtek hdaudioC0D0:      Mic=0x1a
snd_hda_codec_realtek hdaudioC0D0:      Mic=0x19

but produces no sound output.

FWIW, openSUSE Leap 15.3 kernel is based on 5.3 but got tons of
backports, hence its HD-audio part is almost equivalent with 5.13 or
later kernel (except for the recently changed mute-LED handling --
which must be irrelevant with your problem).

The above indicates that the codec is detected and set up.  The rest
part is often some vendor-specific quirks.  For that, details are
missing completely.  At best please give alsa-info.sh output (run the
script with --no-upload and attach the output).


Oh, of course. Now attached.

I see that the Headphone mixer switch is off by some reason.
But it should have been toggled by PulseAudio.

You can test like:
   amixer -c0 set "Headphone" unmute

Simple mixer control 'Headphone',0
  Capabilities: pvolume pswitch
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 87
  Mono:
  Front Left: Playback 87 [100%] [0.00dB] [on]
  Front Right: Playback 87 [100%] [0.00dB] [on]


Also, just to be sure: did you install both pulseaudio and pipewire?
They may conflict.

Yes. pipewire is now gone.

Still no sound but I might need to restart...

Thanks!
