Marcus,

Thank you for informing me about the issue, but I must admit I don't
understand it at all and I hope I will succeed to find somebody who could
explain me what I am supposed to do...
:) I suppose this is related to my soundcard Audiphile 2496 and it could be
connected with its driver problem or similar, but, I cannot assume more of
that right now.
Forgive me for beeing honest with you and thank you.

Zoran
