[alsa-devel] [[PATCH] snd-asihpi: 1/8] Control naming
From: Eliot Blennerhassett eblennerhassett@audioscience.com
Clock source is neither capture nor playback, so change 'Capture Clock' to 'Clock'. Add spaces to control name string for consistency, always 'PCM 0' , never 'PCM0'

Use the card drained status reporting for playback, but allow it to persist for a few timer cycles before signalling XRUN, to allow card to recover by itself.

Allow older non DMA capable cards to use MMAP by emulating the DMA using read and write functions, and getting rid of copy & silence callbacks that were used only by older cards.
