Add SND kcontrol to SOC USB, which will allow for userpsace to determine which USB card number and PCM device to offload. This allows for userspace to potentially tag an alternate path for a specific USB SND card and PCM device. Previously, control was absent, and the offload path would be enabled on the last USB SND device which was connected. This logic will continue to be applicable if no mixer input is received for specific device selection.
An example to configure the offload device using tinymix: tinymix -D 0 set 'SNDUSB OFFLD device select' 1 0
As I mentioned in another patch, the control element name should be more understandable. The same applied even for ASoC stuff. The current name is way too cryptic.
thanks,
