I wondered if you clever people might be able to help...

I have lost sound on video playback on my PC (Windows Vista Home Premium edition)- it effects dvds (but only *some* dvds, strangely) and YouTube.
I gather that this may be some codec issue- but am loathe to start messing around with codec settings etc in case my audio settings are effected.

Any ideas on how to address this issue?

Thanks,

Here (http://www.codecguide.com/download_kl.htm) you can grab the K-lite mega codec pack and install it. There are many different versions of the pack, but since you can select what you do and don't want to install, it's best just to get the mega pack. At the very least you will get a ton of codecs you never had, and also reinstall all of the codecs you already had. That should fix your problem if it is codec related.

I have a similar problem, only on an XP SP3 machine. Ocassionally, while watching movies thru either VLC or Media Player Classic, the audio goes out. When this happens I check my Foobar player to see if any audio works there. Sometimes yes, sometimes no. Sometimes, I only need to restart the player, but often it requires a reboot.

Try to uninstall the audio drivers. I don't think it's a codec problem.

CCCP is another great codec pack...either way you go, I would definitely go the route of exploring codecs before uninstalling sound card drivers. I have had these same issues, and I have very rarely uninstalled then reinstalled a driver to fix the issue (not to say that this isn't the fix in some situations).

On the topic of drivers, you could always check to see if there are newer versions available for your sound card. That was the case for a video display issue I had, and it turned out that there was a newer driver for my video card and low and behold that fixed the problem...but again, I never had to uninstall the driver, rather just use the update driver option in the device manager. It will let you know if you are using the most current version or not.

yeah i find cccp is just newer and has alot more to it.. but again k lite works for those who use it.

yeah video card drivers are a pain in the arse too sometimes. so check yer system before it poops on you.
