[Solved] No sound output with custom kernels

American_Jesus · 2015-09-01 23:07:58

Since kernel >=4.1 (linux-ck/pf/zen) i got no sound output, but it works with -ARCH kernel or <=4.0.9-ck.
Already tried stopping/removing pulseaudio, i have no ~/.asoundrc so can't be a configuration fault.

Tested the mic and it works, and i can hear the mic output, but not from pcm

$ aplay -l

Notice some differences with alsa-info.sh

4.1.6-1-ARCH: http://www.alsa-project.org/db/?f=8bcf7 … 105abfa9de
4.1.6-1-ck: http://www.alsa-project.org/db/?f=8eb7b … 1ea88cc440

here's a diff: https://gist.github.com/Generator/4be98cd6e5011c59988c

tried using /etc/modprobe.d/modprobe.conf

options snd-hda-intel model=auto

and

options snd_hda_intel enable=0,1
options snd_hda_intel index=0
options snd slots=snd_hda_intel

with no luck, i'm out of ideas of what can be

Problem solved, it was a wrong power state, weird only happens with custom kernels

solved with:

dev="/dev/snd/hwC0D0"

hda-verb $dev 0x10 SET_POWER 0x0
hda-verb $dev 0x13 SET_POWER 0x0
hda-verb $dev 0x17 SET_POWER 0x0
hda-verb $dev 0x1d SET_POWER 0x0

running a script at startup fixes the problem

Arch Linux
