This locks up KDE due to kmixer somehow trying to stay attached to the audio device after resume from suspend-to-disk. This is the second time of dealing with this (or a similar bug) with the usb audio device:

I got it working by using the head of the git tree recommended in that thread (unfortunately I don't have the hash it was related to).
If the recent git works, it should be the series of my patches:
73d38b13ffb105ab633bd91969c8d218b2de38d4 [ALSA] Fix the race of card instance unregistration f18638dcf0c481eca2430206ebcdc7295aec8623 [ALSA] Clean up snd_card_free*() 9eb70e68f38bbc5996a2193e7b7dc0b5487a08cb [ALSA] usb-audio - Fix race in reconnection
But the patches are intrusive, and I'm not keen on applying them to stable trees...
OK, finally had the time to try the newer master and here's what I get now;
I suspend and resume fine, but the sound card no longer works again after resume and the only thing I see in the dmesg is:
[ 125.873947] usb 3-1: reset full speed USB device using ohci_hcd and address 2 [ 126.017265] snd-usb-audio 3-1:1.0: no reset_resume for driver snd-usb-audio?

Forgot to mention the hash for this one is linus tree: f26a3988917913b3d11b2bd741601a2c64ab9204
