From b7334b1a81994bf3005a8999dd779c85683f86c0 Mon Sep 17 00:00:00 2001 From: Antonio Borneo Date: Sun, 13 May 2012 00:06:23 +0800 Subject: [PATCH] pcm: add missing "break" in "switch" A missing "break" in procedure snd_pcm_write_mmap() causes execution of "case SND_PCM_ACCESS_MMAP_NONINTERLEAVED" to fall through next "default" case of the "switch" statement. Since "default" handles error cases, the procedure returns error. The error fixed by this patch blocks transfer of capture data from kernel to application. Execution get stuck in alsa-lib, that discards all received data.
