flash plugin makes horrible sound

[merlin23]

Does anyone know how to configure the flash-plugin in mozilla to make a normal sound?
All I can hear is a very bizarr sound that makes my ears hurt...

I use 2.4 kernel , also tried it with 2.6. My mp3-player and xine is working fine, so I don't know whats the reason for this...

I have installed my system new a time ago, but the problem is stil not away...

thx m*
