media player 6.4, media player 10, media player classic.
midi, wav, mp3.

winamp works perfect with audio files on the pc with problems.

when using media player 6.4 under properties - advanced
these filters in use are listed.
-cirrus logic usb-dvr2 splitter
-default directsound device

on the xp pc that has no problems playing audio files.
when using media player 6.4 under properties - advanced
