Nobody needs to do reverse engineering or to beg to get detailed information from the vendor, if the vendor doesn't provide a driver. However, accessing the software mixer requires a driver. Btw. among other prosumer and pro audio devices I own a prosumer Focusrite Scarlett series class compliant USB audio device (a 18i20) of the 2nd generation. For at least some, if not all of the 1st generation Scarlett audio devices, Linux provides access to the hardware mixer, but not for the 2nd generation. By now already a 3rd generation exists. IOW just because a driver for a particular revision of hardware does exist, it doesn't mean that all revisions are supported. _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
