If it was a broken cable, lose connection or durty contacts, it didn't cause
the sound to decrease or increase it's volume, which it's what it happens.
In case of a broken cable or durty connector, there would be interruption of
the sound and possibly scratchs sounds. What happens is this...

Imagine that your are listening to music, let's say with the volume at 1/2
level....
Sudenly, I turn the volume knob fast to 1/4 of the level down, leave it
there for, let's say 1 second and then turn it to 3/4 of level fast.

This is what it's happening but with no one touching the knob or cables.

This happens without touching the unit. I just turn it on, set the volume
to 1/2 level or eaven to 1/4 level, initialy it plays Ok....but after a
short while, the sound goes down, like if I had turn the volume to
minimum, it stays low for a few seconds and then comes up, sometimes to
the original level, and sometimes to maximum (almost). When it starts
doing this, it continues to do without stoping. I don't need to touch it
to happen....it simply happens. If it are the capacitors, which ones ones
should be causing this?

Hi there,

I have a Creative DTT2200 6.1 Sound system that I have bought a few
years ago. It have worked fine up until a few weeks ago. Now during
playback, the sound goes up and down sudenly without touching the volume
knob. I have checked the main board and power supply, thinking the
problem could be located in one of the many electrolitic capacitors that
might have been damage (for example liking fluid out or with the top
expanded) but no capacitor is damaged. Does any one have a clue what the
problem is?

Please post reply in this news or send me email to the above adress.

Thanks a lot.

Capacitors can fail without visible damage. But this "sounds" more
like an intermittent and/or aground problem. Try cleaning the controls
and looking hard at any interconnects. You also may have a cold-solder
somewhere. Can you make it happen by tapping the unit from various
angles, or shaking it, or tapping the controls or connections?

You're assuming that the speaker unit is bad. It might not be. Check the
audio cable that connects to your sound card. Might have a broken
connection in the speaker unit or in the plug on the end of the cable.
Check the connection at the output jack on the sound card. Might just be
a loose or dirty connection. Or it might have inadvertently been pulled
loose.
