Hardware Mute in the Audio Reference Design

[AlexAdvice]

I have a problem to implement hardware mute in my design.

 

As it written in documentation, I make mute/unmute in the audiostream.xc in functions:

void UserAudioStreamStart(void);
and void UserAudioStreamStop(void).

There are 2 problems:

1) in DSD mode the Mute line is unmuted  ~150ms before DSD/PCM line is set to DSD.

2) in PCM mode, when I stop streaming, the Mute line is muted after ~2 sec (!).

 

Are any solutions?

 

Thank you.
