From cfd6081c83dbee2ae270d82df3487d13129118e2 Mon Sep 17 00:00:00 2001 From: JongHo Kim Date: Tue, 17 Dec 2013 23:02:24 +0900 Subject: ALSA: Add SNDRV_PCM_STATE_PAUSED case in wait_for_avail function commit ed697e1aaf7237b1a62af39f64463b05c262808d upstream. When the process is sleeping at the SNDRV_PCM_STATE_PAUSED state from the wait_for_avail function, the sleep process will be woken by timeout(10 seconds). Even if the sleep process wake up by timeout, by this patch, the process will continue with sleep and wait for the other state.
