Re: reading sound card output?

I realized I omitted some info: I'm only getting 3 lines showing up on
your program.

Also, I wrote the following program to see if I could get a valid
speaker port and record from it. The port was valid, but I can't
record. I assume that's because as a port the speaker is play only,
not record.
