Hello,
since your sound device support update in 2023 I have no sounds any more in my P3Dv5.4 GSX version, no matter what sound device is selected. Also, In the GSX settings I have the choice between devices with the prefix "openAL" sound device and "generic" sound device. It seems I only can select "openAL". Everything worked fine until your 2023 update, all drivers are installed, and every single following GSX update hasn't changed this, so what is causing this please, as obviously I am not the only one encountering this problem.
