It seems like an issue with the USB ALSA kernel driver. Report this issue to relevant tracker: https://bugzilla.kernel.org (Audio group).

[perexg]

Also, you should have a confirmation from PW developers that it's really an ALSA issue.

@perexg cheers, thanks for the heads up. will do.

edit: ~would this be under Drivers > USB ?~ nvm, found it. Drivers > Sound(ALSA)
