From 822fa19b5c23746577687a0ec48eae0ec1cd22a0 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 2 Jun 2009 14:12:17 +0200 Subject: ALSA: ALSA: ctxfi - Release PCM resources at each prepare call The prepare callback can be called multiple times, thus it needs to release and acquire the resource again by itself at the second or later call. Simply add pcm_release_resources() at the beginning of each prepare callback in ctatc.c.
