Description Oleksii Shevchuk 2012-03-21 22:20:05 UTC

After updating from 3.2.9 to 3.3.0 internal microphone produces no sound. Booting with 3.2 with ~same config fix issue.

Here are my /proc/asound/card0/codec#0 from 3.3 and 3.2

Could you give alsa-info.sh output (run with --no-upload option) on both working and non-working kernels, instead?
