saw this post from 10 years ago and im having same problems 10 years later. still not fixed.

Here's a scenario:
Rider 1 listens to his own music.
Rider 2 listens to his own music.
Open a 2-way intercom, music is paused for both riders.
Pre-fw 5, if Rider 2 drops out of the conversation, his own music resumes and Rider 1's own music resumes.
The way it works with fw5:
If Rider 2 drops out of the conversation, now he's listening to rider 1's music. Holding down the jog dial by either rider simply pauses rider 1's music. Once the intercom is open, there is no way for rider 2 to listen to his own music. Rider 2 is either stuck listening to someone else's music, or has to close down the intercom connection completely.

thats the issue somtime i loose my music all togetther or have to listern to music of my partner its not good given the price we payed for the dual system
