ALSA 0.9.6 already supports the ALC650, you don't need to install the
Realtek driver.

An AC'97 codec handles only one audio stream. Mixing of audio streams
would be the task of the AC'97 controller, which is part of the
chipset's southbridge. Intel, SiS and nVidia southbridges don't mix;
some recent VIA southbridges do support hardware mixing (of four
streams), but this doesn't work on many motherboards.
