[alsa-devel] [RFC PATCH] ASoC: dpcm: Apply symmetry for DPCM
by Koro Chen 13 Dec '15

13 Dec '15

From: PC Liao <pc.liao(a)mediatek.com> DPCM does not fully support symmetry attributes. soc_pcm_apply_symmetry() is skipped in soc_pcm_open() for DPCM, without being applied elsewhere. So HW parameters cannot be correctly limited, and user space can do playback/capture at different rates while HW actually does not support it. soc_pcm_params_symmetry() will return error and the second stream stops. This patch adds soc_pcm_apply_symmetry() for FE, BE, and codec DAIs in DPCM path that was skipped in soc_pcm_open().
