[SOLVED] Issue with USB sound card (module, I assume?)

Well, basically I have Focusrite Scarlett Solo as my external sound card. And for some weird reason sometimes when I boot everything just works and sometimes it's not.

Basically (when it doesn't work):

aplay -l

I'm trying to modprobe snd-usb-audio but no luck. Here's what dmesg says:

I'm not sure what might cause this

Now, I'm rebooting and look:

aplay -l

(Not only asound/cards sees Scarlett Solo now, it also successfully sees my MIDI keyboard. Which is not too surprising since they share the same module but still)

And it used to be the case since the first day of installation. I literally don't do anything to fix the problem: just reboot everything. But it starts to unnerve me little by little to be honest so I was trying to understand what exactly is causing this seemingly random behavior. But yeah... I'm out of ideas that's why I'm asking for help!

Re: [SOLVED] Issue with USB sound card (module, I assume?)

Welcome to the forums. Have you tried an other Kernel? I've had similar problems with an Audigy Rx with recent Kernels, so I've installed the linux-lts package, what worked for me. Maybe this is worth a try?

Re: [SOLVED] Issue with USB sound card (module, I assume?)

Please use [ code ] and not [ quote ] tags when pasting output.

Switching the kernel won't help here this issue can and does usually happen with an incorrect/incomplete modprobe index override definition. You have to either explicitly define every index you expect to have or use  negative indices for "not so relevant" devices. e.g.

options snd-usb-audio index=0,1
options snd-hda-intel index=2,3 #Or index=-3,-3 to tell them to take whatever's free as long as it isn't 0 or 1 since we reserved those for the usb modules

Fixed!

options snd-usb-audio index=0,1
options snd-hda-intel index=2,3

Yeah, that helped. Thank you a lot!

Re: [SOLVED] Issue with USB sound card (module, I assume?)

Having similar problems. I'm afraid I don't understand what/where
options snd-usb-audio index=0,1
options snd-hda-intel index=2,3
refers to. It would appear as though "options" was a command, which it isn't AFAIK.
Would be most grateful for help here, serious problems as none of my usb audio devices are working as of a few days ago.

Re: [SOLVED] Issue with USB sound card (module, I assume?)

That refers to: https://wiki.archlinux.org/index.php/Ke … probe.d/_2

But this particular error can only happen if you either consciously already defined things there (in which case this question would be weird...) or if your distribution placed incomplete/incorrect configuration already (... in which case we wouldn't know)

In any case, we do not support different distributions, precisely due to these uncertainties in their configuration in comparison to an Arch Linux install, I suggest you ask on a debian forum for further help, and maybe post a dmesg/journal log there so people can actually aid you with informed troubleshooting.

Closing this old solved thread.
