Here is some data from the PC that I have to use at work: 0 = onboard 
analog audio, 1 = NVIDIA HDMI (with 4 outputs, out ow which only one 
corresponds to a physical connector), 2 = Logitech USB Headset H340 
(borrowed from a colleague).

I guess I need to redo the patch, because the numbers don't add up, 
especially for the USB headset. I.e. there is significant latency that 
is not covered by tv_this_profile.
