Any ideas on how to improve the sound on this computer?

New Dell/Windows 8. Just reinstalled the audio driver. On some vids, e.g. some YouTube videos, that I have had in my favorites for a long time and that worked just fine, the sound is garbled, unintelligible, and/or too quiet. I notice, also, that on the little VU meter that accompanies the sound setting in Windows, that the sound seems to barely move the “needle.” I have, of course, adjusted the sound on the video as well as on my computer. I’ve discovered this with several videos, but not all. I have the latest Adobe Flash Player. What might I be missing here?

There probably was a change in the default sound setting.

Not all YouTube videos use Flash. Do the videos that work happen to have ads in them? Some of those require Flash, while most other videos don’t.

If so, I’d think your web browser is messed up. I’m not sure how to fix it other than reinstalling (if that’s possible). A workaround would be to go to http://www.youtube.com/html5 and disable the HTML5 player.

Ok - I usually use Mozilla Firefox, but I downloaded Chrome just to try to see if the browser was the problems. Nope. One of my favorite old videos is just toast. Maybe it’s the actual video that has been corrupted, but the other ones play just fine. Any other settings I can fool around with?

If you’re watching a video more than once or twice, you may as well just use DownloadHelper (or a similar add-on, there are tons) to just save it to a HDD. Won’t solve your problem, but meh.

Here’s something that might be diagnostic - when I view a YouTube video, sometimes, of course, there’s a commercial built in. The commercials sound fine. But when the actual video starts - nada. That sounds like something wacky with the settings on my computer, but I don’t know where else to look.

If you see the commercials at all, you’re doing the internet wrong.
