Re: [alsa-devel] [PATCH 1/4] ASoC: da7213: Default to 64 BCLKs per WCLK to support all formats

From: Peter Meerwald-Stadler
Date: Mon Aug 08 2016 - 03:53:04 EST



> Previously code defaulted to 32 BCLKS per WCLK which meant 24 and
> 32 bit DAI formats would not work properly. This patch fixes the
> issue by defaulting to 64 BCLKs per WCLK.
