Okay Kim you seem to have a handle on this sound stuff... explain this to me. I can now hear output, but I can't set any of the parameters like are set in the pcmplay example...

The pcmplay example is obsolete...

So 8 KHz wave files come out sounding like a record playing super fast. In order to get pcmplay to work, I have to comment out all of the mixer ioctl's which set the format, frequency, etc...

The audio input is locked at 44KHz, 16-bit stereo, little-endian signed with buffer size of 4608 bytes (size of one mpeg frame). If the program only outputs PCM at 8KHz, you need to manually convert it into 44KHz .
