This is bizzare.
I can hear music a sounds just fine but if some one tries to talk, it’s either garbled or the sound is very low.
Any ideas on how to fix this would be appreciated.
I have window vista if that helps.
Are people talking in videos? Or on Skype, for example?
Try reinstalling AC3 filter; and check audio settings for any Skype or voip usage as microphones and speakers can sometimes get jumbled.
No, I’m talking about DVD, streaming video, everything.
I am wondering if it is some sort of mixer issue, in the event your sound drivers include a mixer. Perhaps some of the frequencies that cover the human voice are turned down a lot. I know that the frequencies for human voices are a subset of the frequencies for music, so it is a long shot.
Do you have 5.1 sound enabled? Try stereo sound only.
