[SOLVED] Pulseaudio stopped recognising audio devices after update

hagfish · 2016-04-14 09:48:34

After a reboot, gnome's "Sound" settings don't list anything under Output, and pavucontrol only offers HDMI/DisplayPort output (with nothing connected). I don't know which update triggered the problem, since I ran multiple updates between reboots. The only debug info I know is the output of 'pactl list', which only lists one card:

[...]

I don't know how to troubleshoot further, but will gladly post more info if just told how.

aplay -lL
dmesg

should help. If the ALSA layer already only detects one card it might be a kernel issue and you might want to try the lts kernel to see if that is the case. There was a new major kernel upgrade which might still have some issues

Thanks for the help, here's 'aplay -l':

I couldn't find anything very relevant in dmesg, 'dmesg | grep sound' returned only:

[    1.440013] input: HDA Intel HDMI HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:03.0/sound/card0/input13

Based on these it seems to me that the ALSA layer isn't detecting the card, so I'll go and try the lts kernel. I'll report back when I've figured out how to do that.

Using the lts kernel fixed the issue, here's current ouput from 'aplay -lL':

In case that others have the same problem: I'm on a Dell XPS 13 laptop, with an Intel integrated sound card (if I'm reading the above output correctly).

I'll go ahead and mark this as solved, but should I still be reporting this as a bug somewhere?

V1del · 2016-04-14 14:04:13

Its apparently already known and somewhat documented https://wiki.archlinux.org/index.php/De … 5%29#Audio You might have a case to get that flag/module added to the arch kernel config

loki · 2016-04-16 05:59:02

How are you doing this, I can not edit the needed flag (DW_DMAC__CORE) to y.

What am I missing here?

Edit: Sorry I missread your solution, nothing to see here, carry on
