this is dsp - I think it is compatibility layer to older OSS. What you also want to look at is: $ ls -al /dev/snd/ total 0 drwxr-xr-x 4 root root 340 Jan 6 16:10 . drwxr-xr-x 17 root root 14400 Jan 18 21:06 .. drwxr-xr-x 2 root root 60 Jan 6 16:10 by-id drwxr-xr-x 2 root root 80 Jan 6 16:10 by-path crw-rw----+ 1 root audio 116, 10 Jan 6 16:10 controlC0 crw-rw----+ 1 root audio 116, 12 Jan 6 16:10 controlC1 crw-rw----+ 1 root audio 116, 8 Jan 6 16:10 hwC0D2 crw-rw----+ 1 root audio 116, 9 Jan 6 16:10 hwC0D3 crw-rw----+ 1 root audio 116, 3 Jan 14 23:19 pcmC0D0c crw-rw----+ 1 root audio 116, 2 Jan 19 08:05 pcmC0D0p crw-rw----+ 1 root audio 116, 4 Jan 6 16:10 pcmC0D2c crw-rw----+ 1 root audio 116, 5 Jan 6 16:45 pcmC0D3p crw-rw----+ 1 root audio 116, 6 Jan 6 16:45 pcmC0D7p crw-rw----+ 1 root audio 116, 7 Jan 6 16:45 pcmC0D8p crw-rw----+ 1 root audio 116, 11 Jan 14 23:19 pcmC1D0c crw-rw----+ 1 root audio 116, 1 Jan 11 18:08 seq crw-rw----+ 1 root audio 116, 33 Jan 6 16:10 timer output might differ on your end but usually all is hidden behind pulseaudio. you can set the precedence of the audio card by configuring the index parameter for it for example in /etc/modprobe.d/alsa-base.conf or custom conf file there options snd_hda_intel index=0 options snd-usb-audio index=1 this tells the computer to use the hda_intel card as first one and the usb audio card as second.
