From 6a9a440681f2170b9a07b1cf28c6aa7532c307c8 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Sat, 27 May 2017 15:50:44 +0800 Subject: ASoC: zx-i2s: fix harsh noise with 16-bit audio The audio parameter setup in zx_i2s_hw_params() works fine with 32-bit samples, but for 16-bit ones, all we can hear is harsh noises. As suggested by vendor driver code, DMA burst size and TS width should always be 32 bits, no matter audio sample is 16-bit or 32-bit. Follow the suggestion above to fix the harsh noise issue seen with 16-bit audio samples.
