Discovered internal mixer controls - digi00x #17

Closed zamaudio closed 8 years ago

zamaudio commented 9 years ago

Hi Takashi, I found the following controls for internal mixer matrix. It is able to route any single capture channel to 1, 2, or 1+2 (stereo) using the following registers:

// Value 0 = off
// Value 1 = on

Thanks. But I have never tested these functionality because no idea to implement it in usespace. By the way, are there some registers to control gain of each analog input or output?

Regards

zamaudio commented 9 years ago

No gain registers that I know of. Besides there are knobs on the panel for that.
