dsound vs waveout regarding problem with 48kHz on ISA cards

[MaxHill]

Some more info: I have DirectX 8.1 but I have tried all of them from 6 to 9.0b an it is the same on all versions.

Selecting waveout device didn't help Ac3 movies plays at half the speed audio and video too and you cannot do anything with it I have tried even the speed setting but it does nothing (i can still hear some noise in the audio even when it is played at half the speed [slow]).

And waveout device with mp3 audio streams is still noisy (no change).
The speed is correct though.

I just remind you and thanx for help so far that this problems occurs only when it comes to 48kHz everything from 44.1 and lower is perfect on dsound and waveout too.

I've been thinking, is there any possibilty to use WinAmp's OUT plugins with BSPlayer or if anyone knows about some WinAmp DSP plugin which does downsampling (like 48kHz -> 44kHz, 48kHz -> 22kHz etc.) please let me know.

Heck, I've even tried the newest drivers for my soundcard from Creative (but they are from 1998) with no succes, 48kHz still sucks under DirectX's DirectSound.
