The code introduced in commit1f91ecc14d("ALSA: oxygen: modify adjust_dg_dac_routing function") accidentally disregarded the old value of the playback routing register, so it broke the "Stereo Upmixing" mixer control. The unmuted parts of the channel routing are the same for all settings of the output destination, so it suffices to revert that part of the patch.
