--------------------------------
commit 805ce81826c896dd3c351a32814b28557f9edf54 upstream.
In the current setup the PA is left unmuted even when the Soundwire ports are not started streaming. This can lead to click and pop sounds during start. There is a same issue in the reverse order where in the PA is left unmute even after the data stream is stopped, the time between data stream stopping and port closing is long enough to accumulate DC on the line resulting in Click/Pop noise during end of stream.
making use of new mute_unmute_on_trigger flag is helping a lot with this Click/Pop issues reported on this Codec
