Galaxy S3 T999, 4.1.2 rooted, iGO Primo 9.6.29.341779, US maps.

TTS is setup using either the installed Google or Samsung TTS engines, neither one changes the issue.

What I'm getting is it mutes all other sounds when it announces a maneuver for example "Take next right."
When it announces "Prepare to turn right after 1000 feet." for example what I get is it announces over any other sounds the "Prepare to turn right" and the "after 1000 feet." has any other sounds mutes as I'm expecting.

I've been searching any sys.txt examples I can find but none of the settings appear to change the behavior.
And if I change to one of the natural voice options it mutes as I expect but I don't get the extra information TTS gives me.

Anyone have this issue and or know what I can do?

Thank you,
Robert

Well, my solution has been to go back to version 9.6.22.317625, but I really liked the skin in the newer version and the mute button.
