@ mfueeg ,
Follow up information.
I have stereo speakers plugged into the PC motherboards sound jack.
I also have a USB Headset with Mic (corded not wireless) available for flight sim listening or when I do videos with headset sound and Mic for recording my audio (narration).
The stereo speakers are always connected to the motherboard jack.
I did a screenshot of the Device Manager Audio with this configuration.
When I use the USB headset plugged into any PC USB port it cuts out the stereo speakers sound so PC audio is only heard in the headset.
I did a screenshot of the Audio Device Manager with this configuration.
In a previous post you mentioned you chose "headsetsystem."
"A headset and in p3dv5.2 - soundsystem i choosed the headsetsystem.
Have another look at your P3D Sound Options when using your wireless headset.
Is there also a (selection dropdown) choice to use the Default Primary device?
