+ * NOTE:

+ * even if streaming. To start streaming at the current sampling rate is only
+ * way to revocer this state. GO46 is better for stand-alone mixer.
+ *
+ * Both of them have a capability to change its sampling rate up to 192.0kHz.
+ * At 192.0kHz, the device reports 4 PCM-in, 1 MIDI-in, 6 PCM-out, 1 MIDI-out.
+ * But Yamaha's driver reduce 2 PCM-in, 1 MIDI-in, 2 PCM-out, 1 MIDI-out to use
+ * 'Extended Stream Format Information Command - Single Request' in 'Additional
+ * AVC commands' defined by BridgeCo.
+ * This ALSA driver don't do this because a bit tiresome. Then isochronous
+ * streaming with many asynchronous transactions brings sounds with noises.
+ * Unfortunately current 'ffado-mixer' generated many asynchronous transaction
+ * to observe device's state, mainly check cmp connection and signal format. I
+ * reccomend users to close ffado-mixer at 192.0kHz if mixer is needless.
