The thing here is that default:x seems to be the only way to get a
card to open compatibly with most setups. I tried opening with
plughw:x, hw:x, dmix:x, and any other prefix that was suggested, but
default:x was the only thing that worked with my dmix-based ALSA
setup. Since dmix is on by default in ALSA, I'd venture that most
normal sound setups would break otherwise too. dmix:x worked with
dmix, but still behaved oddly (I don't remember exactly what it did),
and I reckon that it probably wouldn't work with setups that don't use
dmix.

Does anyone have a suggested device-opener that is both correct
according to API/docs and correct in that it actually works with at
least dmix?
