Train Simulator Sound Blocked

Hi

When Norton is installed I have no sound on Dovetails Train Simulator Classic. All other programs works fine and the issue is only when I use the main sound device.

Basically
SPDIF and Norton installed = No Sound
HDMI and Norton Installed = Sound from monitor speakers
SPDIF and Norton with everything deactivated = No Sound
SPDIF and Norton uninstalled = Sound is OK

The are no error messages and the game is set to allow all.

I am running the latest 24H2 official release of windows on a MSI X870E Carbon mainboard with a 9950x CPU and 7900XTX GPU. All other games and programs are running fine. I cannot find any setting in Norton to prevent it from blocking the sound on this particular game on this particular sound card.

Any help would be appreciated

Just in case anyone finds this the issue was with the latest version of Norton. I contacted Norton support and we worked the problem and in the end we went back to the previous software release number 22.24.2.6 with the interface I was used too over the last few years. With this release everything worked again. The engineer hoped in the near future the new release would be fixed for this issue.
