Good day,

I am running Arch Linux, Kernel 4.8.12-2, Pulseaudio verson 9.0 and am unable to consistently connect my headphones (Steelseries Siberia V2).

Combinations of un/re-plugging in the headphones and issuing of:

pulseaudio -k

And they may eventually become operational.

Please see relevent dmesg output:

  • The many errors in dmesg indicate that there's a problem with the generic ALSA USB driver. Possibly the Steelseries Siberia V2 gives inconsistent information and needs a "quirk" exception in the kernel driver, or whatever. Debugging on the pulseaudio level probably doesn't help. I'd disable pulseaudio, verify the problem persists with ALSA alone (use aplay), and file a bugreport for the ALSA project. – dirkt Dec 8 '16 at 11:47

I suspect that it is not power related nor a sampling rate issue, but rather an initialization one specifcally with the handshake and passing over of devices between Alsa and Pulseaudio.
