I am running SDRTrunk on our statewide 700 trunk system. I have 5 sites coming in, but audio only comes from one site. Can I change which site audio comes into/out of the computer?

You state you are monitoring 5 sites, are all 5 sites within 25-30 miles of you? Is SDRT locking onto the control channels for each site? Do you have an alias list setup for each site and listen turned on?
If yes to all the above questions then you should receive audio from each site.

@Enforcer52 all sites are within that range, they are locked in to control channels (showing yellow control), alias lists are set up, all talkgroups are set to listen.
Still this morning after I reset everything, only 1 site plays audio. All sites are recording but not all play audio.

Strange, I have 23 sites setup and all play audio. Never ran into this problem as long as alias was set up and listen turned on for TGIDs.
If you STOP the site that is coming thru, does any of the others then have audio? Have you tried one site at a time to see if they play any audio.
What 5 sites are you listening to and did you add thru RR database or manually?
How many dongles are you using?

No. There's no site audio selectivity in SDRTrunk. It goes by alias (talkgroup)
So I realized this morning I have 4 sites coming in, one is a duplicate CC frequency.
I am using one dongle, I did add most TGID through RR, some were manually entered.
I just tried the sites one at a time, no audio on any excepted the one that usually has audio. I noticed no site shows radio traffic in the now playing section, except the only site I usually hear. I do see radio traffic under events and I hear it on my radio (official and allowed on the systemnot set up for NAS) when affiliated to the correct sites.
I will build a new alias lists and try that.

My first thought is you don’t have enough dongles to cover all control channels and voice channels for all the sites. What is the highest and lowest of the frequencies on each of the sites? And what is the spectrum coverage of your existing single dongle?
Created a new alias list...boom...working as it should. Thank you guys, now fours sites worth of yapping.
Nope, lost them. I started editing the alias lists and back to only one tower playing audio. I guess no editing to keep more audio going or no audio and have the alias list corrected.
Knowing what sites and how many sdr dongles you are running would help us to help you.
1 dongle, MSWIN system, Pearl River site, Philadelphia Site, Walnut Grove Site, Four Corners Site.

Which dongle do you have?

One rtl dongle will not cover all those sites concurrently in SDRtrunk.
Well I guess that is the issue. I wonder why it picks the one it does for audio?
Using those 4 sites you would need at least 3 dongles to cover them all. Even if you want to listen to only 1 site you would need two dongles to get all the traffic.

@Enforcer52 @jtwalker @Whiskey3JMC gotcha. Well I guess I will just use the one to record for now, listen to what it pulls in from WG, and start purchasing more to listen to them all later. jtwalwhiskey3
Thanks again guys, I appreciate the help.
