I have been tinkering with op25 for the past few weeks and I am at the point where I am ready to use it to replace my BCD996P2 for streaming my local p25 phase 2 system. I have everything setup and I can see an established connected between my ubuntu server and the audio1.broadcastify.com server, but no audio is passing through. Can someone help me troubleshoot what is going on? I have local audio playing through the computer, but nothing on the broadcastify side.
I am also having trouble locating the liquidsoap log file... i am running as a non privileged user and cannot find the proper way to write the log file to a location this user has access to.
Here is my op25.liq file
