Card only needs about 4K buffer. } What do you mean by primary memory? If it ain't on the card it's not what I want. If it's not on the sound card a slow device elsewhere on the system will be able to starve the sound card. } >I've recently been using a SoundBlaster AWE 64 Gold, with a 200Mhz } >MMX Pentium running 3.0-RELEASE.

As soon } an IDE unit is used in the system. mp3 playing becomes a lot easier } disturbed task. } } Advise .. use SCSI ONLY.

I don't have any of that junk on any of my systems. My problem is insufficient buffering on the sound card. Poor card design. I'm almost certain that this is a problem endemic to most all current systems. Given a bit of load just about any configuration will fail to deliver uninterrupted audio. (At least for 200Mhz CPUs and below.) A larger on-card buffer would make the problem go away. So are there any good sound cards out there?
