Hi all,

This is a patch for sound/usb/quirks.c which enables DSD support for a 
new T+A DAC for which we have developed the USB firmware. Here is a 
patch description:

This patch adds the T+A VID to the generic check in order to enable 
native DSD support for T+A devices. This works with the new T+A USB DAC 
model SD3100HV and will also work with future devices which support the 
XMOS/Thesycon style DSD format.


I hope you can apply this patch. Let me know if you need more info.

Thank you,
Udo
