ASoC: fsl_audmix: make clock and output src write only (944c517b) · Commits · 戴 / test

"alsactl -f state.conf store/restore" sequence fails because setting "mixing clock source" and "output source" requires active TDM clock being started for configuration propagation. Make these two controls write only so that their values are not stored at "alsactl store". Signed-off-by:
