Hi there,
my problem is that my internal audio stopped working. In pavucontrol, internal audio is missing.
My USB Devices (Headset, USB-Micro) are still working....

In alsamixer, I can select the PCH-card, but with
aplay -l
only HDMI but no PCH card is detected:

So, is there anything I could do?
thx in advance

Pulseaudio can do nothing if ALSA can't see the internal device. Did you ever attempt to do any ALSA configuration? What output do you get for
sudo dmesg | grep -iE 'snd|sof'
do you have a time frame of when this issue appeared was it a specific kernel or software update? Under certain circumstances there could be a conflict with the HDMI and the internal device

Hi there,
sudo dmesg | grep -iE 'snd|sof'
gives back an empty line....
The problem occured last week, I tried to downgrade Pulseaudio, but it did not bring back my internal audio.
I also have the lts-kernel, but it does not solve my problem either....

Is your dmesg buffer overflowing? That should at the minimum give you information about the detected devices. Try a
sudo journalctl -k | grep -iE 'snd|sof'
instead.

thx for your answer, the command gives

as far as I understand, the "no codecs found" seems to be the culprit. Searching for this, I think I'll have to wait for a new kernel.... or?
