USB soundcard only works after unplugging and plugging in again

[mcmurdyy]

Hello,

I have an USB Sound Card/DAC which is not recognised by Linux Mint 18.3 at bootup/reboot. It doesn't appear in the Audio Settings and it doesn't appear either in aplay -l
When i unplug it and plug it back in it works fine.
Does someone know how I can make my card recognised at startup?

The output of inxi -Fxz after unplugging and plugging in again:

Before unplugging the card it gives the same output, just without the Audio Card-3 device.

Are you using a USB 3 port? Try a USB 2 one.

It is already connected to a USB 2 port.

When sound is NOT working, in the terminal type lsmod | grep snd and paste back the result.

Okay. For some reason, snd_usb_audio is not loading at boot, and I assume does when you plug in the device. Verify this with lsmod | grep snd when sound is working.

I think the easiest solution in that case is to open /etc/modules for editing with gksudo xed /etc/modules and add a new line at the bottom of the file with snd-usb-audio (you don't need to worry that I didn't use underscores there.) After adding the line, save the file and reboot.

If you prefer to hunt down the real source of the problem, my best guess is ACPI might be the cause and might need to be turned off in grub. However I don't know enough about it to advise any further.

Hope that helps.

Unfortunately that doesn work either. Now snd_usb_audio is loaded at boot-time, but it still doesn't recognise the card. Also the lsusb command doesn't show the card until replugging in.

[MrEen]

Okay. Sorry about that. I guess you should reverse the change to /etc/modules and we'll have to wait for someone else to help. Like I said I'm guessing ACPI needs to be off, but that's not something I have any experience with and I don't want you to end up unable to boot at all.
