another WDM problem

[Rock Star 87]

Hello everybody, and how do you do? I am running a Santa Cruz with my new WDM driver downloaded off of the Turtle Beach Website. I was using the driver that came with the soundcard (VxD, I believe) for the longest time, and I liked that one, but I needed to record external audio into FL Studio, and that requires ASIO, which requires a WDM driver My only problem is that with my old drivers, I recorded synth onto wave, and there were never any clipping issues, but when I'm finished a synth recording, I look at the wave and there are parts that are clipping. I down them 3 decibels and they look like every part that clipped got cut flat. When I normalize, they clip again, which never happened to me before in Pro Audio 9.3. I'm so confused. Anybody get my drift?

What is the OS? If you were using VxD before, that is usually for the Win98 world isn't it? WMD may jsut be harder to handle int hat OS than in the win200 and XP OS's.

Also, what is your card set to for buffers, I think that can affect it, if your system is taxed, it can be a fine line between performance and stability that way.

I don't think you can set the buffers with the SC. I used to have one and used WDM in Win98SE ok.

The new drivers may have simply reset the levels. IIRC, you can have the record level in the cards control applet (or Windows record mixer) set above unity, that is there is gain even on the line inputs with the faders set to max. I think about 7/10ths of fader was ok.

Those WDM drivers are a great thing. If you choose to set it for multichannel operation and set the cards input and output config to suit, you can do 4 track record and have line out for speakers and another jack driving the headphones. The control applet gives a color coded picture of what the jacks are assigned to, which I thought quite cool.

Adding ASIO (Asio4all), I found I couldn't get very low latency. Like the Soundblasters, there's a DSP chip on the SC card that adds latency ASIO can't get around. I think something around 15ms was the best I could manage, but that was ok for playing soft synths.

the clipping issue has turned out to be only a small part of the problem, now I'm hitting horrible underruns. It can hardly play some of the more complicated FL Studio songs, though I have it set to buffer as much as possible, regardless of horrible latency.

PS. why does latency matter, if everything starts at say 160ms after it's requested, shouldn't everything still line up in the end?
