[alsa-devel] [PATCH] ALSA: usb: Fix support for Denon DA-300USB DAC (ID 154e:1003)

[Takashi Iwai]

From: Frank C Guenther <bugzilla.frnkcg at spamgourmet.com>

Fix problem where playback of Denon DA-300USB DAC sometimes does not
start and leads to error messages like "clock source 41 is not valid,
cannot use".

Solution: Treat this device the same as other Denon/Marantz devices in
sound/usb/quirks.c.

Tested with both PCM and DSD formats.
