There is a more generic way to detect DSD capability of popular UAC2 implementations. Advantage is that each new device with DSD capability doesn't have to be explicitly listed through VID:PID. XMOS/Thesycon implementation uses this method. As a safety precaution I have still left VID detection in place. Many of the implementations use XMOS' VID, but not all. I have moved over the devices that have been tested with these patches. Likely more of at least XMOS VID ones could be removed from the explicit list, but I opted for careful approach. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
