This allows for N different devices to use the pioneer mixer quirk for setting capture/record type and recording level. The impementation has not changed much with the exception of an additional mask on private_value to allow storing of a device index: DEVICE MASK 0xff000000 GROUP_MASK 0x00ff0000 VALUE_MASK 0x0000ffff There is perhaps room for removing the duplication in the lookup tables (name, wValue, wIndex) and deriving these. See the code header comment to understand how this can be achieved. Feedback is very much appreciated as I'm not the most proficient C programmer but am learning as I go.
