Does anyone else get worse sound quality - less treble (propably due to lower sample rate), "scratchy" sound and more pitch quantization - in GPL with DirectX 7.0a? The difference to DirectX 6.1 is easy to hear when using engine sounds with lots of treble. The problem isn't always present: After viewing a replay it is sometimes possible to get normal sound, but as soon as the engine rpm goes below certain limit, GPL (or DirectX 7.0a) switches back to low quality sound. I have a Diamond MX300 (Diamond's own drivers or latest refence drivers by Aureal) and Win98. Previously I have stayed with DirectX 6.1, but since it was disk formatting time anyway, I gave DirectX 7.0a another try. Thanks for any help. Jari Jokinen

I get scratchy sound sometimes, am running 7a but really thought it was more because I was running the SB Live card. If I knock down the sound volume in windows slightly, it seems to go away. -- Don Burnette Dburn in N3 and Legends "Jari Jokinen" <[email hidden]> wrote in message news:8ckpdb$qcg$[email hidden]... > Does anyone else get worse sound quality - less treble (propably due to > lower sample rate), "scratchy" sound and more pitch quantization - in GPL > with DirectX 7.0a?

Doesn't help in my case:( My ears tell me that GPL just swithces to lower sample rate (not lower pitch) and uses rougher pitch quantization with DX7.0a. Jari Jokinen Don Burnette wrote in message ... >I get scratchy sound sometimes, am running 7a but really thought it wasmore
