Hi,
On the hardware described in attached alsa-info (VT1705), I have the following problem:
- mic doesn't work
- if, while recording, we switch "input source", mic works during the recording session.
Passing power_save=0 as a parameter to snd-hda-intel solves the problem.
It was reproduced on linus' master branch, tiwai's for-next branch, and 3.2 branch.
Regards,
Anisse
Hi,
The log showed that your machine had two microphones, one is an internal mic, and the other is a rear mic. Which microphone did you use? The log showed currently used mic is the internal mic. The rear mic was not plugged in a
jack.

On this hardware, there's only an internal mic, and no physical jack to plug another input.
So " mic doesn't work " means recording fail or playback as aa-path fail? And could you mail me log file when power_saver=1? Thanks.
Lydia
