alsa-mixer: add support for Astro A50
This MR adds support for the Astro A50 USB gaming headset. It uses 2 outputs, for voice and multimedia, but unlike the SteelSeries headsets it supports stereo on both.
(edit: already answered)
This MR works, but I think I still need some help: The port names in pavucontrol are shown as
steelseries-arctis-output-game-common- how can I change that?
The headset is marketed as "3D Audio ready", whatever that means.
aplay -Lshows some surrondXY devices, but I can't get speaker-test to use them - where should I be looking for help with that?
