ALSA: usb-audio: Eliminate noise at the start of DSD playback. Copy mainline DSD playback pop noise fix
torvalds@0120073#diff-cc9fc192670bbec31122ad6874641755
[Problem] In some USB DACs, a terrible pop noise comes to be heard at the start of DSD playback (in the following situations).
[Cause] At the start of playback, there is a little silence. The silence bit pattern "0x69" is required on DSD mode, but it is not like that.
[Solution] This patch adds DSD silence pattern to the endpoint settings.
