*
* ALSA PCM applications can know the XRUN by getting -EPIPE from PCM operation.
* Then, they can recover the PCM substream by executing ioctl(2) with
* SNDRV_PCM_IOCTL_PREPARE. 'struct snd_pcm_ops.prepare' is called and drivers
* restart packet streaming.
*
* The above processing may be executed before this bus-reset handler is
* executed. When this handler updates streams with current isochronous

* Without streaming, the devices except for Firewire Audiophile can mix any
* input and output. For this reason, Audiophile cannot be used as standalone
* mixer.

* NOTE:

* even if streaming. To start streaming at the current sampling rate is only
* way to recover 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
