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.
Mic doesn't work means recording fails. Except if, during the recording, I use the "Input Source" control to change to another input, *and then back* to "Internal Mic". If I start another recording, it will still be silent unless I repeat the previous sequence.
I don't use mic directly for playback (with hardware a-a path)
Please find the full log and alsa-info in attachment with power_save=1.
