From: Eliot Blennerhassett <eblennerhassett@audioscience.com>
Cards without settable local samplerate and without SRC
still must have a valid samplerate.
This fixed rate is determined by reading the current rate for the card.

Make playback silence callback a no-op, card automatically outputs
silence when written data runs out.
Increasing update interval and thus minimum period avoids xrun on startup
or because of timer jitter.

Replace local VPRINTK1 with snd_printdd.
Create local snd_printddd instead of VPRINTK2 for most verbose debug.
In most cases let snd_printk supply default level for messages.
