Subject: ALSA: hda - Fix inverted internal mic not indicated on some machines
From: David Henningsson <[email protected]>
commit ccb041571b73888785ef7828a276e380125891a4 upstream.
The create_bind_cap_vol_ctl does not create any control indicating
that an inverted dmic is present. Therefore, create multiple
capture volumes in this scenario, so we always have some indication
that the internal mic is inverted.
This happens on the Lenovo Ideapad U310 as well as the Lenovo Yoga 13
(both are based on the CX20590 codec), but the fix is generic and
could be needed for other codecs/machines too.
Thanks to Szymon AcedaÅski for the pointer and a draft patch.
