The following commands can switch between rear and front audio codecs on Linux.
Tested with the current BIOS version (0.29.x) and Linux Mint 19.2.

Instructions:

First install alsa tools:

Code: Select all

         sudo apt install alsa-tools
To enable the front codec:

Code: Select all

        sudo hda-verb /dev/snd/hwC0D0 0x14 0x71f 0x41

        sudo hda-verb /dev/snd/hwC0D0 0x18 0x71f 0x41

        pulseaudio -k & sleep 1 & sudo alsa force-reload
Now the front codec should work and the rear codec is disabled until next reset.

To switch back to the rear codec, the user can either restart or run this:

Code: Select all

      sudo hda-verb /dev/snd/hwC0D0 0x14 0x71f 0x01

      sudo hda-verb /dev/snd/hwC0D0 0x18 0x71f 0x01

      pulseaudio -k & sleep 1 & sudo alsa force-reload
The upcoming BIOS release will include a menu item for switching between rear and front codecs on Linux.
