Hi,
I'm working on CX20582 HDA support for OLPC.
We have a choice of 50% or 80% microphone bias on the 2 microphone ports
(one inbuilt, one socket for external devices). Any suggestions on which
one we should pick or how to decide?
We can't hear any difference between the 2 settings..should we choose
50% for potential power savings?
Daniel
