Oh.. I guess I was wrong, I feel like there must be a way to configure the
sound from within pygame instead of setting an environment variable...

Yeah, I suppose more likely than not you will want to record sound coming from
the game also.

That’s understandable for removable interface.
I did see that your sound card outputs 4 channels what about the stream count?
I think they present as subdevices if they are actual discrete streams, but not
if they are coupled channels.

I… your welcome but if you bought a dedicated multichannel audio card or
interface you should be able to route multiple sources when/if you need in the
future…
If you made sure to use the same settings (sample rate, format, different
streams/subdevices) you could actually get exclusive control and share the
hardware device. I could be wrong but a 4 ch card is probably going to have at
least two streams available, maybe separate clocks, usually not, or even 4
discrete.
You could not use a hardware device at all, and use alsa’s software
converted/mixed/resampled software plugins/devices sharing input/output will be
much easier. I believe you can also set a system default mixer or plugin,
unfortunately the only thing I remember was that I couldn't not figure out how
to set up alsa the way I wanted it and gave up halfway through :/
But see if $ aplay -L lists software device systemdefaults that seem adequate
for you, then you could try if using those names instead give satisfactory
results, since the audio format resampling will be handled for you by alsa even
if clients use different configurations.
