outout of alsa-info.sh

Hello,

There is no sound through headphone of my ALC295. 
I am on fedora 34. I have noticed the no sound since f33. I have tried many options, reported to askfedora (https://ask.fedoraproject.org/t/no-sound-in-headphone-speaker-works-fine/11101) also, but with partial solutions only.


Though I am using Linux for 15 years, I mostly work as enduser, so I may not know exactly what info you need, I am attaching those I have done before.


cat /proc/asound/card0/codec* | \grep Codec
Codec: Realtek ALC295
Codec: Intel Kabylake HDMI


The partial solution I have achived is by adding 

`options snd-hda-intel model=asus-zenbook`

to /etc/modprob.d/sound.conf 

The problem is it is not stable (I have to plugin-plugout the jack and play with speaker sound before I get the sound in headphone, and also, the sound only stays at peak, cant lower the sound.), may be like bug #212641.


I have tried #195457 but that doesnt seem to have any effect. 


Kindly have a look.

NB: Fedora 34 used Pipewire instead of pulseaudio, if that helps.

Sorry, buy I have missed this:

lspci|\grep Audio
00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)

Is it only about the headphone, and the speaker works as expected?

Comment 3 Barud 2021-05-03 16:16:22 UTC

Dear Takashi Iwai,
Yes. 
The inbuilt speaker is working as expected. No sound in headphone only.

Comment 4 Barud 2021-05-03 18:04:39 UTC

I am not sure if I am giving unnecessary data (and missing the necessary one), but, in a similar topic, they have asked for this info too:
sudo fuser -v /dev/snd/* 
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  root        741 f.... alsactl
                     rudra      1616 F.... pipewire-media-
/dev/snd/seq:        rudra      1610 F.... pipewire

OK, then could you try the patch below?

Test fix patch

Comment 7 Barud 2021-05-03 18:35:51 UTC

patch to which file?

just `patch -b asus-dac-fixup.diff`?

Kindly let me know.

Comment 8 Barud 2021-05-03 18:37:16 UTC

Also, should I remove the /etc/modprobe.d/sound.conf before applying the patch?

Comment 9 Barud 2021-05-04 00:19:04 UTC

Dear Takasshi,

The patch worked. 

In my humble i5 machine it took around 3 hours to compile. 
I didn't had any idea...basically I blindly followed jforbes (fedora kernel maintainer) for that.

One thing is not your exact file, but jforbes gave me a modified version. 

Thanks a lot. I am attaching the modified version.

the same patch rebased to 5.11 (created by jforbes)

Comment 11 Takashi Iwai 2021-05-04 08:21:31 UTC

Good to hear.  The fix patch is now submitted and will be merged to the upstream.
Likely landed in the upstream 5.13-rc1 kernel in the next week.
