Hey,
I've recently bought a SteelSeries Arctis 1 wireless headset: https://steelseries.com/gaming-headsets/arctis-1-wireless-xbox and wanted to write a kernel driver to export a few features of the device, and needed some help getting started.
The receiver shows up as a audio class USB device, with extra features on a separate USB interface.[1]
The extra features that can be accessed are:
- Presence detection. I wanted to use that so PulseAudio or Pipewire
could make routing decisions based on whether the headset is available, or probably better, implementing a "jack detection" emulation for the main audio interface?
- A slider to change the sidetone volume
- Export the battery level
The latter is the only one I know how to do, so I'd be happy with any pointers or examples about the first two items.
I sent this in December and didn't get any answers, and I would appreciate any guidance/examples if you have any into implementing this.
I would imagine that the new features would be implemented through a separate ALSA device with few features, which PulseAudio/Pipewire could merge with the existing USB audio device.
Cheers
