[alsa-devel] Regression post-ALSA 1.0.22 for Lenovo G555 Internal mic

[Roo - Andrew Baines]

Dear All,

I have been told I should send an email to this list from this
bug<https://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.

Regards
Andrew
