My SPDIF Output sends bad data

Hello SevenForums,

This issue just occurred out of nowhere, my optical audio output used to work fine.
Now when i set my "Realtek Digital Output" to default, the bars work as they should and the red light passes through the optical fiber cable. But when it reaches my "receiver" (Logitech Z-5500), it says "No Digital Data".

It is as if my receiver can not read the data that gets sent through the cable.

This issue occurred on my laptop, and i can't figure out what has caused this to happen.

When i take the same cable and plug it in to my desktop's SPDIF Out, it works as normal, the receiver plays audio.

I have tried 3 receivers with the same outcome.
I have also tried to update my audio driver, i did not help.

Does anyone know what i can do to fix this problem?

Best regards.

Nowaka

Update:

I plugged in SPDIF cables to both my desktop and my laptop, and held them next to each other, to see if there were any differences between the two.

I found out, that the signal from my laptop is a bit weaker than the signal from my desktop.

So it has to be either the jack adapter that is weakening the signal, or the laptop that has lost signal strength.

well, this isn't relevant in this forum anymore, so i guess i will close the thread now. (If i just knew how)
