Digital sound via optical output

[blindsleeper]

I use the optical digital output for the Playstation sound.

It goes from the optical cable into an optical / coax converter and it continue in my decoder / amplifier.

I have the problem that (no matter what game) after playing about 1 hour the sound fails, then it came back after some time and falls
again. After reloading the game is back for a short time.

Analog the problem does not occur!

With the PS2 because there were no problems (had the same configuration)
So probably lies at the PS3!
Does anyone else have any similar problem?

Do you have the Visually output as the preferred audio output set?
If not then try it once.

And also try with different optical cables.

I also use the optical output for the PS3 and the PS2 and has never Probs no matter how long I heard the music or done something else.
