Pitch on my computer varies

[buntyj]

The pitch on my computer has suddenly started going up and down. Rather like an old-fashioned 78. I presume it is related to my sound card. The problem occurs both with Winamp and with Windows Media Player. It hasn't done this before and I am flummoxed. TIA for any ideas. [email protected]

have you worked out that it is the sound card? this isn't hard if you havn't

just change the speakers and see if you still have the problem then use the original speakers in someone elses sound system or through a mic

Is the pitch issue only with winamp and widows media player? what about other programs playing sound. is it all?

to test this Just use the windows sound recording tool and  record something then play it back.

how frequent are the pitch changes?
