The vendor Comtrue Inc. (0x2fc6) produces USB audio chipsets like
the CT7601 which are capable of Native DSD playback.
This patch adds QUIRK_FLAG_DSD_RAW for Comtrue (VID 0x2fc6), which enables
native DSD playback (DSD_U32_LE) on their USB Audio device. This has been
verified under Ubuntu 25.04 with JRiver.
Best Regards !
