[alsa-devel] [PATCH 06/28] Rewrite PCM timer function. Update control names.

From: Eliot Blennerhassett eblennerhassett@audioscience.com

Reported samples_played from card may be inaccurate, so don't use it. Update control names to be closer to alsa standard practice. Also fixed some accidentally lowercased strings.
