[alsa-devel] Fwd: Re: no reset_resume for driver snd-usb-audio for logitech headset H600

FWD:

Any news to the snd-usb-audio issue?

Thanks, Bernhard

Old Message:
-------------
I have tested the patch with kernel 3.12.0 with suspend and hibernate, and the problem is gone.

No messages "no reset_resume for driver snd-usb-audio?" or other negative effects/messages.

After resume, the usb_audio_device (Headset) is the master channel in KDE Mixer, as it should be.

=> So the problem is solved for me.

Can you please add the patch to the latest kernels and LTS-kernels or whitelist the workaround for my device (ID 046d:0a29 Logitech, Inc. H600 [Wireless Headset])

Thanks, Bernhard
