Hello. I am really stuck with some audio problems I got recently so I'm coming to you for help! I'll get straight to the point. It seems like my computer doesnt like multiple audio tracks in a video anymore and I dont know why. A couple of days ago I downloaded a high quality quicktime game trailer (.mov). It had video, a narrator voice, and then the noises of whats happening in the trailer. At some point later, my computer decided that the narrator has to go away. Now when I play the video, the narrator can only be heard as a faint whisper in the background. I redownloaded the file in case it got corrupted, and its still acting the same way. I watched a couple of my other videos and they seemed fine. I redownloaded the video in WMV format and tried that. It ALSO has the same problem. Both of these were pretty high quality movies. Big bit rate, excellent image quality, great audio too. My computer had never had a problem with anything like that in the past, though. I downloaded the file a third time, this time reencoded and resized by another person and that files audio worked fine. Could hear everything. I tried duplicating the problem with other videos from the site, but since I never heard them when I knew it was working, I dont actually know what to listen for if something is wrong with them. All I know is that at some point my computer decided the narrator had to go and it seems like its just cutting out audio tracks. I've done everything I can to fix it. Going through every bit of sound settings that there are on the computer, reinstalling the audio program, updating it, updating drivers, rolling back drivers, reinstalling drivers, trying different programs, updating drivers that may even be loosely associated with audio, running programs that detect broken drivers, running virus scanners, using system restore, all of that. After all of that I've just about given up. All that over a measly video game trailer. Seems like it would just be the file itself, being corrupted or something, but ive tried various formats and redownloaded multiple times and it always comes out the same unless someone reencoded it, and i think thats because when they do, it beings the audio tracks together into one track. So, why would my computer decide against multiple audio tracks in my videos? And why would doing all that i did (I spent half of today working on it) not fix it? Any help is greatly appreciate! GREATLY! I'm so tired of working on this with no results! P.S.: I think this is the right forum, but being a newb, I could easily be wrong. Please tell me right away if I posted it in the wrong place, and where I SHOULD post it!

My guess! I would suggest that you find out what audio format the video has (5.1, 6.1, 7.1,etc) and make sure that your audio adapter is capable of it and is set correctly.

How would I found out what audio format the video uses? And my computer played it fine when I first downloaded it, so I am pretty sure that it IS capable of it. Something changed and I have no idea what, because I didn't do it. Not directly, at least. I hadn't installed anything new or changed any settings.

Windows settings sometimes get tweaked by gremlins or whatever. If it's an AVI file, a program called Gspot 'might' help. If it's not an AVI file, I don't know. Maybe you should wait for other suggestions.

It is not an AVI file, and the same problem happens on both the .MOV and .WMV versions of the file that I downloaded.

How many speakers do you have and what speaker configuration is it set up for? If you have multiple speakers, you might try using different output jacks on your sound adapter and see if it makes a difference. I am not the best audio person around, so it might be best to wait for an expert.

I guess it could be a codec problem, but since it worked at one time, I tend to think it isn't.
