Recordings with microphone are too fast and distorted - pitch is correct

[Vern Hamberg <vhamberg@xxxxxxxxxxx>]

I have a new motherboard and all on a computer that was near a big 
lightning strike last April. I tried recording some stuff just a bit ago 
using a Logitech stereo (I think) mike that plugs into the sound card. 
I've used Sound Recorder, LP Recorder, and Audacity, all to the same 
result - the resulting WAV file plays back and the speaking is too fast 
and has some distortion - I assume some of the digital information has 
been omitted.

The mobo is an ECS GF6100-M754 with an AMD Athlon 64 3200+
Not using onboard sound - I think because I wanted a MIDI port. Not sure 
now - I think the card is a Diamond Xtreme XS51

I do have Sophos antivirus on the desktop - saw that sometimes an AV can 
cause this - have the same AV on a thinkpad - no problem there.

Someone here said there is some kind of (clock) fix for Athlon 64 bit 
CPUs and XP - but I could not find it.

So I will appreciate help on this - I might take the sound card off and 
try the on-board sound.

I also have a Xitel INport - very cool - converts from 1/4 inch RCA to 
USB through an opto-isolated AD converter - very clean. I could hook a 
keyboard mixer output to that and see if it works - that bypasses the 
sound card completely.

Might try a USB microphone, as well.

Thx
