sounds stop after several seconds HELP

[braelito]

music stops several (10--ish) into clip. poses a problem for playing songs. i use Creative WaveStudio to convert + edit.

Use Audacity instead, it's free and fairly reliable; or another decent editor I've been told is dbPowerAmp.
Also if you have Nero, WaveEditor is a good choice as well.
Both Creative WaveStudio and Windows recorder are known for creating wave files that do not playback fully in-game.
