From 58dcc48816ad1db8d2e33ddf659c2bda64f645c4 Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Mon, 26 May 2014 16:56:30 +0300 Subject: [PATCH] ASoC: Intel: Clear stored Baytrail DSP DMA pointer before stream start Stored DSP DMA pointer must be cleared before starting the stream since PCM pointer callback sst_byt_pcm_pointer() can be called before pointer is updated. In that case last position of previous stream was wronly returned.
