Windows 7: Ultimate x64 No Sound at all.

06 Feb 2010   #1

Windows 7/Vista 32
Ultimate x64 No Sound at all.

Hello everyone, I'm not too sure where to start explaining my problem. But I'll try and give you all as much information as I can.

So here I am spec-wise:

Windows 7 Ultimate 64-bit
System Model GX700
T9300 2.50GHz
Nvidia 8600M GT

Realtek Drivers.

I noticed something was wrong yesterday when every video I came across, was very very choppy. I also realized that no sound was coming from my computer at all. I thought something was wrong with my video/audio driver, so I went through the song and dance of updating them.

Open up youtube, click a random video. Opens quickly, still shot of video appears. Browser stalls to nearly a halt along with the video, and still no sound. So I went searching for more closure on my problem. I tried openning up a few music files, winamp would open just fine. But no matter what, the timer would not budge from 0:00. Almost like it knows it knows what it is supposed to do, but forgot how to talk. Also, no audio file will open in WME at all. Giving me a C00D11B1 Error.

I decided to do some more troubleshooting. I disabled my audio driver and opened another video. And to my surprise, it ran perfectly without worrying about sound in the first place. Which was good, I'm getting closer to isolating the problem.

So I updated all of my drivers again, configured virtually everything I could get my hands on. The device manager says everything is fine. The Realtek Audio Manager says everything is there and should be working. But when I try and test it. It doesn't do anything at all, no sound check on the speakers, no blue outline, nothing. The basic control panel sound test also gave me the simple error message of "Failed to play test tone".

So I'm left here stumped, an audio problem like this that has just popped up out of the blue is very interesting. I'm right on the verge of simply restoring everything, but I'd like to see this through.

But here's a run-down of my problems in case my entire thought process isn't very important to you.

1)Audio files will open, but will not play.(EXCEPTION: WME Will not open anything)
2)Embedded media players will not play.
3)With audio driver enabled: A video will load, and start playing. But will slow down instantly. There is no sound, and even the smoothest of videos will become extremely choppy.
4)With audio driver disabled: A video will load, and will play normally without having to worry about sound. (My biggest concern)
5)Updating the drivers did not work. Everything is up to date but I get a "Failed to play test tone" error in most config menus. That or nothing will happen at all.

Hopefully there is an easy solution to this. In the mean time, I guess I should start looking for my DVD.

Windows 7 Professional x64

Hello Gebz,

Have you tried a System Restore to a point before the troubles?

What anti-virus are you using? Try running a full scan, and also download Malwarebytes and run a scan.

Could you also post a screenshot of the Performance tab of Task Manager while the video is choppy?
