commit 3c414eb65c294719a91a746260085363413f91c1 upstream.
As per discussion at: https://github.com/szszoke/sennheiser-gsp670-pulseaudio-profile/issues/13
The GSP670 has 2 playback and 1 recording device that by default are detected in an incompatible order for alsa. This may have been done to make it compatible for the console by the manufacturer and only affects the latest firmware which uses its own ID.
This quirk will resolve this by reordering the channels.
