9.4.3 Solving connectivity issues – Dirac Live version
If you are experiencing any connectivity issues, the first thing to do is double-check that your
processor’s plugin and firmware are up to date.
No Internet connection
Various components of the software require an Internet connection. In particular:
• The Dirac Live application may refuse to generate filters or reload saved projects if it cannot connect to
the Dirac Research servers.
In the event that the software is not operating correctly, check that your computer is connected to the
Internet and try again.
miniDSP Flex not detected
The Dirac Live application use network ports 11113, 11115, 11117, 5000, and 8080. The last two in particular are
needed for the bridging app to communicate between Dirac Live and the miniDSP processor.
If the miniDSP processor is not detected:
1. Double-check the USB cabling from your computer to the processor. If you are using extenders or hubs,
remove them and make a short direct connection. Try different USB ports on your computer.
2. Check that your computer’s firewall isn’t blocking any of the ports listed above.
3. Check that other applications aren’t using these ports.
a. On Windows 10, open a command prompt and type the following commands:
netstat -ano | findstr 8080
netstat -ano | findstr 5000
b. On macOS, open Terminal and type the following commands:
sudo lsof -n -i4TCP:8080 | grep LISTEN
sudo lsof -n -i4TCP:5000 | grep LISTEN
If there is no output, the ports are not in use. If there is output, then try to close the application that is
using them. Typically, software that provides a local web server is likely to be the one blocking port
8080.
