I've been struggling with both audio and wifi since i upgraded from
F24 to F25. I went through many advices and suggestions (different
kernels, restarting, reinstalling both alsa and pulseaudio) to solve
the issues with no result.
I don't have any audio feedback from my device (in audio settings
only dummy output is shown). I filed a bug against pulseaudio . I
also provide output from lshw command .
It shows that both wifi and audio devices are UNCLAIMED (don't know
what that mean).
thanks for any help
The alsa-info output in your ticket shows that alsa is not recognizing
your sound cards. That's a show stopper, since pulse depends on alsa
to access the hardware.
You say this exact hardware worked in F24? Then there is an alsa driver
for the device, and it is some sort of configuration error blocking
alsa from acquiring the devices.
You could specify an ~/.asoundrc to sort that out, as described below
(and probably lots of other places on the web). On my
system, /etc/asound.conf is also empty. I don't have ~/.asoundrc, but I
do have the equivalent of an asoundrc in /etc/modprobe.d/soundcard.conf
and it seems to work fine.
A quick search turned up this older page about a problem like yours.
On that page, someone said the following which might apply to your
Actually The Wiki here also describes the case when two cards use the
same module (snd_hda_intel) but you want to specify some desired order
of detection with index=x parameter in /etc/modprobe.d/alsa-base.conf
file and need some way to distinguish them. You should use VID and PID.
Using output of this command:
$ lspci -nn | grep -i audio
outputs this in my case
00:03.0 Audio device : Intel Corporation Xeon E3-1200 v3/4th Gen
Core Processor HD Audio Controller [8086:0c0c] (rev 06) 00:1b.0 Audio
device : Intel Corporation 8 Series/C220 Series Chipset High
Definition Audio Controller [8086:8c20] (rev 04)
I set my Asus H87-PRO modo sound cards order like this
in /etc/modprobe.d/alsa-base.conf :
options snd-hda-intel index=0 model=auto vid=8086 pid=8c20
options snd-hda-intel index=1 model=auto vid=8086 pid=0c0c
Seems working and no additional ~/.asoundrc used yet.
