And again, next try (somehow my mail address has not been accepted despite registration) This patch (against alsa-kmirror) adds mixer support for M-Audio Fast Track Ultra (8R) devices. It should be suitable as a blueprint for adding mixer support to other devices with missing/wrong descriptors. I needed to move some enums to header files, raise MAX_CHANNELS, and slightly modify snd_usb_audio_probe(). If this get accepted I will work on the effects unit in the FTU devices. It's straight forward work based on this.
