The default soundcard to be used with ALSA is that with the index 0 in `/proc/asound/cards`. Usually this is the first
|
|
found sound device.
|
|
|
|
If you want to change this order, you have to find out the name of the kernel module used for that card and then add
|
|
the desired `index` to it in a modprobe file. I appended these lines to my `/etc/modprobe.d/alsa-base.conf`:
|
|
|
|
options snd-hda-intel index=-2
|
|
options snd-usb-audio index=0
|
|
|
|
This way, the internal sound card (which was the primary one) now gets some other index and the USB mini speakers get
|
|
the index 0 and therefore become the new default device for any sounds.
