At one point our whole system played just fine, 2 AMPS, Port, 2 One, 3 ONE SL. Recently our outside speakers (thirds party) which are connected to the AMPs have stopped working. The app shows everything playing, the amps and port both have a solid white light. Ive tried resetting the amps, making new groups, unplugging and replugging, unplugging the amp and plugging it back in, etc. The only thing I havend done is factory reset the amps or trying to use the join button. I dont believe I should have to since everything is showing up in the sonos apps. I hoping for other things to try before we escalate to seeking outside help to check the wiring from the server room to the outdoor speakers.
The only changes we have had lately are upgrading our firewall device as well as unplugging the port device during a server room upgrades.
SONOS AMPS show they are playing, but no sound.

Don’t factory reset them, I doubt it would help.
Instead, try a refresh of your network. Which means repeating some of what you’ve already done, but order is important.
Power off (unplug) all the Sonos devices. Then, while they’re off, reboot your router. Wait two minutes, the plug back in your Sonos devices. I suspect that within two minutes, they’ll have rebooted and reconnected to your network. Then check in your controller and apply any updates, if they show up. Try playing a stream that isn’t from the line in first, which will tell you something, although not everything. After that, try the line in.
If it still isn’t working on the line in, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, Sonos’ lawyers get sensitive about GDPR, I suspect.
There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.
When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Have you disconnected tne current speakers and tried a test speaker to make sure it is the Amp that is the problem?
Paying to have the wires checked should not be tne plan until you are sure they are the issue.
Start playing somethong, disconnect the wires from tne aamp, connect a temp speaker.
If it plays the Amp is good.
Reconnect the wires to tne Amp, go to a speaker and disconnect the wires from It.
Hook the wires to your test speaker, if it plays the wires are good.
If you don't have a speaker (any 4 to 8 Ohm one) Amazon or a local store will sell you one cheap.
