Hi Chai,
Not gonna lie, this is the first time I’m hearing the name “SPDIF/Toslink,” and I’m going through some articles on it right now.
There have been known issues with Realtek drivers in the past, some forum users have criticized Realtek’s severely lacking update policy, and have called Realtek some pretty insulting names, too; but I don’t know how relevant those things are to your particular problem.
The first thing I’ll post is a link to my first-aid-kit list, as usual,
https://forum.fxsound.com/t/no-audio-and-distorted-audio-windows-11-speaker/2449/3
Please let me know if any of those tips make a difference - changing the frequency settings of your devices and finding an optimal match-up for them matters more than you might think, by the way.
Any additional information on your setup would be helpful; for example, I assume you mean you have a device connected to your computer or laptop through an SPDIF port, which leads me to the question: what kind of device? And: does this “disconnect” happen with any device you connect via this port?
Also, what precisely do you mean when you say, “close FxSound completely?” Do you close it with the X on the top right of the interface, do you right-click the tray icon and select “Exit,” or do you disable and re-enable the FxSound device in the sound settings?
Either way, I’ll go ahead and notify Vijay, since this is probably another problem I will not be able to solve by myself.
