Videos Have No Sound On XBox 360 [Fixed]
So, last night I was trying to watch an AVI video file from a USB flash drive on my XBox 360. For some reason, no matter what I did with the audio settings (on the XBox or the television), I couldn’t get any audio. The video worked fine.
Another strange thing I noticed was that the audio portion of the intro that plays when the XBox is turned on was no longer playing. I still had sound effects on the Dashboard, and games behaved normally. A real puzzler.
I should mention that my XBox is connected to my TV via HDMI. And this brings me to the solution of this issue.
After spending about a half-hour fiddling with the audio settings, I finally determined that it’s got to be something with the HDMI cable. Something to do with audio compatibility. So, I went downstairs and grabbed my HD cables that come with the XBox and hooked it up. Voila! Fully functional sound!
I’m not sure on the details of this, but it probably has something to do with the audio codec configuration and sound compatibility with HDMI. When using the standard HD cables that came with the XBox, the sound works normally.
That’s what I’ve been able to conclude. If you have additional information, leave it in the “Comments” section.
Update as of 7/19/2009
I’ve discovered that actually turning the television off and back on resolves the issue. So, it appears this could be a television issue and not an XBox issue.
