|
|
I'm having trouble configuring sound , I just can't figure it out....
Onboard chip is Realtek ALC887 8-Channel HD Audio, according to motherboard manual.
However, kernel detects it as Realtek ALC891
I have 5.1 speakers and front left and right speakers are not working, that's the issue.
Tried different profiles, 4.1, 7.1, changed jacks on speakers and motherboard, nothing helped.... channel mappings were just different, but never right.
Can I change the codec and use ALC887 instead of ALC891 ?
I guess the problem is there.
Code: | $ aplay -L
null
Discard all samples (playback) or generate zero samples (capture)

kajzer,
See /usr/src/linux/Documentation/sound/hd-audio/models.rst Under ALC88x/898/1150/1220 is a list of model= parameter you can feed to the snd-intel-hda at module load time.
Does one of them help.
I knew that you can do channel swapping in /etc/asound.conf but I've not need to do it.
I was doing something silly with my sound and came across it.
Remapping is only useful if you have the right number of outputs but in the wrong places.
The output of alsa-info.sh may be useful too. Put it onto a pastebin please. _________________ Regards,

Thanks for the information, I'll try your suggestion, there are a lot of options to try.
In the meantime here's the output of alsa-info.sh |

kajzer,
I wonder if Front Speakers and headphones are swapped?
Code: | Simple mixer control 'Headphone',0
Capabilities: pswitch
Playback channels: Front Left - Front Right
Mono:
Front Left: Playback [off]
Front Right: Playback [off]
|
The headphones are muted.
snd-hda-intel is not listed as a module. To fiddle with module parameters, you must pass them on the kernel command line. That's a reboot. You can't always unload a module anyway.
Code: | !!All Loaded Modules
!!------------------
Module
amdgpu
chash
gpu_sched
ttm
vboxdrv

It was Loopback Mixing setting actually, in alsamixer, that did the trick.
I changed it from enabled to disabled.
Can't believe it
snd-hda-intel was built into the kernel btw
Thanks a lot NeddySeagoon! |
