Dear list members, After upgrading to kernel 5.10.16, my sound card (HDA Intel PCH Realtek ALC892) stopped sending output to speakers and headphones. Audio files seemed to play.
By downgrading to my latest kernel 5.9.10, sound output worked fine. In both kernel versions, alsa package versions where the same. Also, the card driver snd_hda_intel was installed.
Could you, please, share a couple of ideas on where to search for a solution? Thank you
Hi Tasos, are there error messages in your kernel log from that boot (`systemctl -k -b`)? Does alsamixer show the devices? Are channels maybe muted? What does `aplay -l` show on each kernel? How do you playback files? Do you use pulseaudio? If so, what does `pactl list short` show on each kernel? Do you use JACK? If so, how do you start it and is it started on the correct device?
