Re: [Playerstage-users] alwayson unsubscription failed

[Rich M. <jp...@gm...>]

Is there any reason they both need to be alwayson?  If your receiver is
always on, your producer should be started when the receiver tries to
subscribe anyway.  It could be that Player is trying to turn off the
producer before the receiver since the producer is the first in the list.
Have you tried running without having both always on?
