Subject: [PATCH v2 1/1] ASoC: rt5682s: Add dapm switch to mute/unmute HP playback output
Add dapm switch in playback path to mute or unmute HP output data. We will set and reset MUTE_SFT bit in RT5682S_HP_CTRL_1 register based on switch value to mute or unmute respective channel.

Ok, it was actually effective and muted audio when we test in our platform, possible because i'm tearing down dapm path based on switch value. If we don't have register bits available to mute i'll resubmit the change with virtual switch widget to disable DAPM and stop audio.
What purpose do you want to add an additional switch to power up/down the dapm in the codec driver instead of using existing controls? And we thought the virtual switch you talked about could be implemented in the machine driver.
