ALSA: usb-audio: M-Audio Fast Track Ultra: Add effect controls
This adds controls for the effects section on the FTU devices. Some of these controls need volume quirks. They are added to mixer.c. [fixed missing break by tiwai] Signed-off-by: Felix Homann <linuxaudio@showlabor.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
