--- Comment #9 from Raymond <superquad.vortex2 at gmail.com> ---
Can you post the output of alsa-info.sh

Previous alsa driver only has one master playback volume and switch,  there is
thinklpad-acpi for the mute button

There is no mute cap in pin complex,  only at audio output


https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1072146

The driver got speaker and headphone playback volume after using auto generic
parser

There was patch for changing thinkpad acpi for mute led which bind mute button
to virtual master
