ALSA: usb/6fire - Driver for TerraTec DMX 6Fire USB
What is working: Everything except SPDIF - Hardware Master volume - PCM 44-192kHz@24 bits, 6 channels out, 4 channels in (analog) - MIDI in/out - firmware loading after cold start - phono/line switching Signed-off-by: Torsten Schenk <torsten.schenk@zoho.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
