ASoC: cs42xx8: fix the noise in the right dac channel with mono playback
When playback mono wav with record in background, there will be some nosie in the right dac channel. It seems that the ADC data has been routed to the dac channel. The cs42888 have 8 dac channels, it's appropriate to mute the unused dac channels, and the noise will disappear. Steps to reproduce this issue: arecord -D hw:0,0 -f S16_LE -r 48000 -c 1 a.wav & aplay -Dhw:0,0 audio48k16M.wav Signed-off-by: Zidan Wang <zidan.wang@freescale.com> Signed-off-by: Mark Brown <broonie@kernel.org>
