Message-ID: <1247475045.1759.5.camel@polyethylene> (raw)

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
