[Tutor] PyAlsaAudio with Multiple Sound Cards?

[Rick Sterling]

Hi.

I am pretty new to Python, but am trying to get up to speed so I move over 
to Python from Perl.  One progam I wrote in Perl I am trying to re-write in 
Python. It controls the mixer settings on my sound card.  I managed to 
rewrite most of it by borrowing and stealing from the mixertest.py included 
with PyAlsaAudio.

I haven't been able to figure out on thing however.  I know that normally 
when you assign the mixer with:

mixer = alsaaudio.Mixer("Master")

It seems to use the first card in the system.  My system has two sound 
cards, and I can't figure out how to access the second card.  Digging around 
online I found the following syntax:

mixdev = alsaaudio.Mixer(mixer, id, device)

I don't know what values it expects for id and device.  I have tried using 0 
for the id and using "hw:1" for the device to no avail.  I am sure it is 
something simple, but after trying many different things I still haven't 
been able to figure out how to access my second sound card.

Any help is apprecaited.

Rick.
