Hello David, No experience with audio on the pi, but: I usually just work with "default" on Linux. You can query the possible strings using "aplay -L", if you have aplay (ALSA player) installed; not sure hw:1,0 actually maps to something that can be used for playback. You could check that reading /proc/asound/devices contains kind of a "tree" notation, in a format that's basically
X: [ N - M]: digital audio playback and that would equivalent to hw:N,M, usually. (ALSA's naming remains to be a big f'up, imho). For example, I have a 7: [ 1] : control 8: [ 1- 3]: digital audio playback 9: [ 1- 7]: digital audio playback in there, so hw:1,7 works, but hw:1,0 doesn't. (I still use "hdmi:CARD=NVidia,DEV=1", which I got from "aplay -L".)
