From ed3c177d960bb5881b945ca6f784868126bb90db Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 4 Jan 2017 12:34:14 +0100 Subject: [PATCH] ALSA: vx: Don't try to update capture stream before running The update of stream costs significantly, and we should avoid it unless the stream really has started. Check pipe->running flag instead of pipe->prepared.
