tps65930: MIC does not work

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi!

I use Angstrom Linux with devkit8000 where TPS65930 is installed.
Current kernel version is linux-3.0.17-r115c.

I can't enable MIC working while it worked in 2.6.28-omap and
2.6.32-r78. I suspect the MIC Bias control does not function because I
can't see any voltage level at a microphone jack. Trying to use
alsamixer does not let me achieve the goal.

I already set registers to necessary values (borrowed from working
2.6.28-omap) but no sound is still captured from a mic by arecord
utility.

Please suggest how to fix this issue.

Thanks in advance.
Max
