All streaming audio is blocked?  I would guess that there are no audio codecs installed for it, or they may be corrupt.

Maybe it's corrupt. Try downloading it again. Or maybe you don't have the correct codecs.

First, make sure that the speakers and mic are plugged in the right places. Then make sure that the power is on to the speakers (if they are powered). If that doesn't work, try another set of speakers or headphones on the computer. If that doesn't work, make sure that the driver for the card isn't corrupted. You should reinstall the driver so you know that it isn't corrupted. After that, you should check the manufactures site to see if they have posted any bulletins on this problem and fixes (if any). You can also check the newsgroups for any info. If all this doesn't help, then you should probably be calling tech support.

A lossless codec if it was me, eg, RAW. Or whatever your digicam uses by default, I wouldn't compress it with any other format unless I have a copy of the original format compressed no more than it already is.

Try the XP codec pack from the site below.\n\nAlso try using another media player, like Zoom, Media Player Classic is included with the codec pack.

like already said, you can use Realplayer or other free software alternatives.  Media Player Classic, Real Alternative, Jet Audio Basic, VLC Media Player could probably do it too
