I got them working (sort of) in the end, I was just lacking a USB sound driver. Just a point, the documentation of all these commands is shockingly bad: alsamixer critically depends on /etc/asound.conf, but doesn't even mention it in its man page. It would appear that /etc/asound.conf is wholly undocumented anywhere. aplay likewise just says what its options do, without saying, for example, what form the "name" following -D has, and what its semantics are. Get this wrong and the half error message you get is just "file not found". Last night I booted up the Gentoo live CD, from around 6 months ago, to see if that would give me a clue, via dmesg, what driver I was missing; no, that didn't work, it just gave an error message for the sound. > alsamixer -c 0 shows the motherboard interface, > alsamizer -c 2 shows the pci one. > Perhaps you have more than one interface. Indeed, something comes out of the HDMI socket, too.
