If anyone has any objections, please let me know. ------------------ From: Matus Gajdos [ Upstream commit 4e1462e7cd6a9b920f441842726cc2b9d232673e ] The Cambridge Audio streamer advertises the UAC2 RAW_DATA format on altsetting 2 of its playback interface, but without the DSD_RAW quirk flag the driver exposes it only as a SPECIAL format that cannot be used. Add QUIRK_FLAG_DSD_RAW for the device (USB ID 22e8:ca10), so the altsetting is exposed as DSD_U32_BE, enabling native DSD64/128/256 playback.
