So sadly not all is well in my world the logitech is only registering as a
mono device for some reason.

nevyn at cetacea:~$ speaker-test -c 2 -D hw:Headset


Playback device is hw:Headset
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Channels count (2) not available for playbacks: Invalid argument
Setting of hwparams failed: Invalid argument

it's clearly stereo. lsusb -vv attached for reference
