[SOLVED] ALSA Sound problem: sound card / device suddenly not found

It was all working fine for a while. When I booted today I had no sound.

Using Pulseaudio, in pavucontrol under "Output devices" there is only "Dummy Output".

I tried a lot of commands just to get any output that anyone might ask for.

But I think this one is most important

~  $ cat /proc/asound/cards
 0 [Snowball       ]: USB-Audio - Blue Snowball
                      BLUE MICROPHONE Blue Snowball at usb-0000:03:00.0-2, full speed
 1 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xfe960000 irq 49

While the output when it worked was:

$    cat /proc/asound/cards
 0 [Snowball       ]: USB-Audio - Blue Snowball
                      BLUE MICROPHONE Blue Snowball at usb-0000:03:00.0-2, full speed
 1 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xfe960000 irq 49
 2 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xfe800000 irq 51

So for some reason, without doing anything overnight, the "Generic" audio card has vanished. (that is the one that I need to use)

Just for completeness I include all other output.

Re: [SOLVED] ALSA Sound problem: sound card / device suddenly not found

Rebooting once did not help. Rebooting a second time did help. But for next time: Any idea what can cause linux to not see a sound device on boot?
There is also a small problem I have always had in Linux: When I boot, I must always have a jack plugged in. Otherwise I will not get any sound and I have to reboot with a jack plugged in.
(I did have a jack plugged at all times during this issue)

Re: [SOLVED] ALSA Sound problem: sound card / device suddenly not found

Post a journal log when the issue reappears

sudo journalctl -b

and maybe, just generally

systool -vm snd_hda_intel #Needs sysfstools

a common cause of "randomly" not seeing a sounddevice is a misconfigured modprobe.d configuration where an incomplete set of index arguments can lead to the situation that a soundcards intended index is overriden by another and thus it is blocked from loading.

Also are you dualbooting a Windows? Did you ensure to disable fast-boot there if that is the case?

It seems to me your Snowball gets on the way. Can you post your /etc/modprobe.d/alsa-base.conf? Perhaps you can add Snowball to its indexing.

Re: [SOLVED] ALSA Sound problem: sound card / device suddenly not found

Alright it happened again, and this time additionally I had an XKey midi usb keyboard connected so:

  Sections:

I did indeed earlier edit /etc/modprobe.d/alsa-base.conf to make the right soundcard be default, contents provided by V1del in the previous forum post I made:

$ cat /etc/modprobe.d/alsa-base.conf
#This shifts the analog card to position 0 and the HDMI card to 1
options snd_hda_intel index=1,0
#This tells the snd_usb_audio to take whatever index up to 2 -(index+1) but if 2 isn't free it's also free to take position 3
options snd_usb_audio index=-3

And maybe useful:

$ cat /proc/asound/modules
 0 snd_usb_audio
 1 snd_hda_intel
 2 snd_usb_audio

Edit: About dual-boot, I have Windows on another disk entirely. That means that when I want to boot into Windows, I have to go into BIOS and change boot order of disks, so I don't think this counts as dual boot.

Re: [SOLVED] ALSA Sound problem: sound card / device suddenly not found

$ cat /
proc/asound/modules
 0 snd_usb_audio
 1 snd_hda_intel
 2 snd_usb_audio

As my intuition told me, ALSA is reading from your USB card instead of the intel module. Perhaps set snd_hda_intel in your /etc/modprobe.d/alsa-base.conf to index to 0 and the rest negative.

Re: [SOLVED] ALSA Sound problem: sound card / device suddenly not found

Ah well yes that makes sense, sorry I didn't realize you were the same person. If that's a situation you are in often (having multiple different sound devices), we can make the original  proposal more failsafe with e.g.

options snd_hda_intel index=-2,-1
options snd_usb_audio index=-3,-3

That way it should at least be able to load, and not fail should any more devices be around, while still having the same "ordering" guarantees. (If you have more than these two USB devices you can also "pad-out" the indices by adding a few more -3 than just these two)
