Yes, there are two receive audio channels for the Main and Sub receivers in the CODEC. The Windows driver level control adjusts both channels identically. If there is any unbalance or for some reason you want to independently adjust the two channels, it can't be done. The driver communication with Windows should trigger the stereo level control, but doesn't.
The CODEC is the TI PCM-2902.

There also seems to be some kind of AGC action going on where the levels actually change over time. This appears to be eliminated by the chip manufacturer's CODEC driver that I found online, though it is still monaural. You still have a left and right channel, you just can't set the levels independently, correct? I haven't seen the AGC issue, but maybe I haven't noticed the levels changing very much. Who is the chip mfr?
