Hi,
For stereo playaback, you mentioned that below mixer setting helped right as your userspace was sending stereo file as left only file to the kernel space
amixer -c es8316tegra cset name="I2S5 Playback mono to stereo conv" "COPY"
Ref: Only left channel can play sound in the "Video" APP - #20 by Xzz
Am I missing something?
Thanks
