amixer controls output
Most interesting is the end of file:
numid=18,iface=MIXER,name='Beep Playback Switch'
amixer: Control default snd_hctl_elem_info error: Invalid argument
Regression since which kernel version? Please give alsa-info.sh outputs on both working and non-working kernels. Run the script with --no-upload option and attach the outputs to Bugzilla (don't paste). Created attachment 256555 [details]
Alsa mixer info for correctly working kernel
Created attachment 256557 [details] Alsa mixer info for 4.12-rc1 During alsa-info invocation I've got: > /usr/sbin/alsactl: get_control:247: Cannot read control info '2,0,0,Beep > Playback Volume,0': Invalid argument > cat: /tmp/alsa-info.a2rAnfcIyQ/alsactl.tmp: No such file or directory > > Your ALSA information is in /tmp/alsa-info.txt.BjqnrFmndN So I assume that it can be cut off Created attachment 256559 [details]
Alsa mixer info for 4.12-rc1 with disabled CONFIG_SND_HDA_INPUT_BEEP
(In reply to Takashi Iwai from comment #2) > Regression since which kernel version? As I wrote in description, since 4.10.0 It looks like that ALC299 has no loopback mixer while the driver tries to set. Could you try the patch below? Created attachment 256561 [details]
Test fix
Indeed it helped. Thank you for a quick response and fix! Thanks for a quick test! I submitted the fix patch now to upstream. It'll be merged to 4.12-rc2 and backported to stable kernels eventually. |
Created attachment 256541 [details] dmesg After plugging-in headphone jack, there is no sound. I've investigated that the problem is in Beep Playback codec (see logs of amixer controls result). After recompiling modules: snd-hda-codec, snd-hda-codec-generic and snd-hda-codec-realtek with disabled CONFIG_SND_HDA_INPUT_BEEP mode, everything works ok. This is a regression bug, because ubuntu kernel (4.10.0-20-generic) with this mode turned on works good.
