The static is the soundcard trying to play 16-bit data through a 8-bit DSP. At least that's the impression I get. The soundcard may in fact support 16-bit audio, but the driver doesn't know how to talk at 16-bits. If there is pcm support, use it as voxware is old and neglected. Except for native support in voxware (you'd probably have to read the code, and chances are it's broken already) I really don't know that there is much you can do except a) buy a new sound card or b) turn off 16-bit audio. The Yamaha sound card (which runs under the pcm code) can usually be found for just under $20. -- Kris Kirby UAH Mail <kirbyk@email.uah.edu> UAH CS <kkirby@cs.uah.edu> Home <kris@airnet.net> WWW <nomurphy@hotmail.com> ------------------------------------------- TGIFreeBSD...
