There's at least one USB audio chipset out there which supports only one
non-standard rate (ID 0e6a:0310 supports 46875Hz). There's a few other
patches for this card which are unsatisfactory because they attempt to
map this rate to 44.1k leading to sound distortion.
The patch below uses SNDRV_PCM_RATE_KNOT to properly support the
non-standard rates where they are available.

Orignally proposed by Sam Revitch <sam.revitch@gmail.com>.
Unregister device files at disconnection to avoid the futher accesses.
Also, the dev_unregister callback is removed and replaced with the
combination of disconnect + free.
A new function snd_card_free_when_closed() is introduced, which is
used in USB disconnect callback.

From: Sam Revitch <sam.revitch@gmail.com>Recently a Turtle Beach Audio Advantage Roadie device ended up in my
possession.  It seems to work with the snd-usb-audio driver, but only
using the headphone jack in 2-channel mode.  The device has a DIN
connector carrying six more channels that are otherwise silent.
C-Media has freely available documentation for the CM106 chip around
which this device is based, and enabling 8-channel output, or
6-channel output with the headphone jack following the front pair is a
matter of setting one of its registers.
Attached is a patch to try to enable 5.1 output mode at probe time.
It seems to work correctly with my device.  There is quite list of
other configurables for this device that might deserve controls.
