Dear All,
I have been told I should send an email to this list from this bughttps://bugtrack.alsa-project.org/alsa-bug/view.php?id=5367 (0005367).
There is a regression in ALSA 1.0.23 and above for Lenovo sound. The internal mic no longer works. A helpful guy 'Raymond' on the bug identified that pin-ctls is correct in ALSA 1.0.21 and 1.0.22, but incorrect in higher versions due to SND_PCI_QUIRK_VENDOR. This is based on alsa-info.sh run on systems using different versions of ALSA but on the same system.
The jacksense has never actually worked but I have always managed to use hda-verb to do this for me - the main issue is the regression with the internal mic.
Try the latest alsa-driver snapshot from ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz
and pass model=auto. If this doesn't work, please give alsa-info.sh output at this state.
thanks,
Takashi
