Ok, so there are two volume and mute elements for playback and one
volume and mute element for capture. The playback elements have the
same name, "PCM", and they are distinguished by their index (0 and 1).
PulseAudio doesn't currently support multiple elements with the same
name, so only the PCM with index 0 will be used by PulseAudio. Which
one is it, mono or stereo? Probably mono, since hw:1,0 is mono and
hw:1,1 is stereo.
Below is the path configuration for your card. There's no path
configuration for the stereo output due to the limitation I described,
so users may still have to adjust the alsa mixer manually to not have
too low volume on the stereo output.
By the way, what's the exact model of the headset? And what's the udev
configuration line that you're using? It seems that there are two USB
headsets, "Arctis 5" and "Arctis 7". I'll assume Arctis 5 in the file
naming below. Not that this matters at this point, but when I submit a
patch, I need to know the exact model.
Create file
/usr/share/pulseaudio/alsa-mixer/paths/steelseries-arctis-5-output-mono.conf
with the following contents:
[Element PCM]
volume = merge
switch = mute
override-map.1 = all
override-map.2 = all-left,all-right
Create file
/usr/share/pulseaudio/alsa-mixer/paths/steelseries-arctis-5-input.conf
with the following contents:
[Element Headset]
volume = merge
switch = mute
override-map.1 = all
override-map.2 = all-left,all-right
Then use
paths-output = steelseries-arctis-5-output-mono
in the mono output mapping and
paths-input = steelseries-arctis-5-input
in the input mapping.
Does this make the gnome UI work better?
