Well, this is the current state of affairs:
--recording with "arecord -r 48 -fdat test.wav works
--playback "aplay test.wav" works
--playing a music file foo.wav with aplay works
--playing youtube doesn't work
--playing the same foo.wav file with audacious doesn't work: it
displays the message "ALSA error: snd_pcm_open failed: No such device"
(searching for that string in menuconfig returns nothing)
