ALSA [was: Re: [PD] [ot] rme hammerfall]

[vanDongen/Gilcher]

In theory you could use the alsa-lib api to look up card names through card 
numbers. I think you can "scan" through the asoundrc this way. The 
documentation in alsa-lib is pretty much non-existant. 

Since the Alsa code in pd was pretty sloppy, the last time I looked, maybe the 
whole alsa part should be redone. OTOH if portaudio works, why maintain the 
ALSA part?
