First let me say that I did a quick install of FreeBSD 10.0-CURRENT
(r249439) onto a spare system yesterday and was able to play various
source material with no glitches. Then I back ported the 10.0-CURRENT
/sys/dev/sound tree (r249715) to my 9.1-RELEASE system and this solved
my remaining audio issues. There were bug fixes but it looks like the
bulk of the changes add support for USB Audio v2.0.

I did find usbdump earlier but don't know enough about usb audio to be
able to identify any problems.

The Dragonfly supports 44.1, 48, 88.2 and 96 and one goal of mine is to
not be doing any additional conversion so I'm hoping it's not doing that!

Attached. I also installed usbutils and have attached output from "lsusb
-v".

hw.usb.uaudio.debug was very helpful the original sample rate mismatch
problem.
One thing that's annoying is the way dev/sound/usb/uaudio.c is
structured, the sample rate is programmed in the Dragonfly only when the
device is inserted; there's no way to change rates once it's plugged in.
Thanks for the suggestions.
