Re: Intermittant buzz/distortion from receiver through...
This could be multiple issues and needs to be diagnosed on site.
Dirty power can cause this, nicks in any speaker wire, faulty speaker, faulty receiver, etc.

Try to attach your speakers to another device, DVD player, Amp., Receiver, etc. and if the buzz is not there; then you know the problem is with the computer. Check the inputs and be certain they are clean and make perfect contact with the plug ends. If contact is positive; and the sound still has a buzz; you are experiencing line noise that requires a software fix. Down load Divx or some other application and see if that works without distortion? Match up the color of the plugs to the color of the input on the sound section of your computer. If they are incoorect, you can experience a problem there as well.
This is a grounding issue either between pieces of equipment or inside the receiver itself. There are other possible causes, but this will almost always be a grounding issue. I recommend unplugging everything and hooking it up piece by piece till the buzz return to isolate the issue. IE - start with nothing but the receiver and speakers hooked up. Turn on the radio. If the speakers buzz, the receiver has an issue and needs to be repaired or replaced.
If there's no buzz, hook up the DVD player. If the buzz returns, there's some issue between the DVD and the receiver.... If the buzz hasn't returned, hook up the.....<insert name of next piece of equipment here> you get the idea.
actually the harddrive could also be the problem, because when you do have a problem with your HDD your computer tend to intermittently hangup or freezes that causes the distort effect on the sound system. Also you could try using your speaker on a different computer or plug it on an mp3 player so that you could eliminate the factor that your speaker has the problem and if not try using another HDD for your computer or worst case scenarion would be changing the motherboard of your computer.
I was struggling with the same problem with my friend piano. You need to replace check module which is plugged near power transistors. I found two bad transistors g109 and q119 (2SA1015). Changing those transistors and remaking soldering joints solved this problem.
Could be the result of having DTS compatible equipment connected through the analog inputs on the VSX-409D. Noise and distortion will result as essentially the DTS signal is being played back undecoded. If this is the case you'll have to connect your LD or CD player through the digital connections (coax or optical) and set 'Signal Select' (button on front) to 'Digital'.
Try to see if the reciever will make the buzzing/noise without anything connected to it except power, and speakers. Tune into a local radio station and see if the noise continues. If the noise has stopped, then you know there is an issue with the player or cable.
