[alsa-devel] [PATCH 06/28] Rewrite PCM timer function. Update control names.
linux at audioscience.com
linux at audioscience.com
Thu Feb 10 05:25:59 CET 2011
From: Eliot Blennerhassett <eblennerhassett at 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.
