Automatic SW slew mute on ADAU1701 JAB5
Hi, i have a project using Wondom JAB5 ADAU1701 built in.
The problem is, there is always a "click" / "pop" sound when play / pause / stop the music. like a hard switching on - off (typical class D amplifiers).
the i try to use clickless SW slew mute in volume control block.
when audio played, i sunddenly click the SW slew mute in sigma studio, result : click / pop switching sound are gone.
But, is there any way to do this automatic? so when i play music and stop, it gives soft mute.
-Thanks

You can change the 'trigger time' parameter as you want.
You can also search for more posts/solution in the forum; there were a lot of discussions and projects available on this topic. I just searched with the term 'Auto mute ADAU1701' and got this post
