Now, what Jaroslav listed above suggests that he chose carefully where he put 0dB. I was just wondering about that. Jaroslav, how did you choose where to put 0dB?
FWIW all the drivers I do take whatever the datasheet says the gain/attenuation range is for the control in question. For most modern embedded CODECs there will be multiple user controllable gains in the path.
We really need to get an API for exposing path information to userspace to fully describe what's going on here.
