Sound drops when I switch a light on

[narkeddiver]

Hi,

I'm looking for suggestions on the cause of the following problem and any ideas regarding a solution

We've moved to a new home and I've set up my home theatre the same way I had it before - computer attached to TV by HDMI and attached to sound system via toslink (unfortunately no HDMI in)

I've noticed when I'm playing music from my computer and switch a light on the sound drops out for a second

However if I'm playing a cd in the sound system the sound isn't affected, neither is the video signal to the TV

I thought maybe the light switches are causing a power drop on the circuit and that was causing the issue but I'm not sure why nothing else is affected

Any thought?

[IMHO]

1. Check the toslink cable for damage or bad connection

2. Re-organize your wires so that AC wires are not parallel to any audio signal cables, and only ever cross over them at 90 degrees

3. Try a different light bulb if it's LED or CFL, or a new ballast if it's a fluorescent.

I hadn't considered damage to the cable- maybe it got damaged in the move. I'll switch the sound to the HDMI cable and see if it's steady coming out of the TV - I guess that'll help rule in or out the toslink

Sorry for the delay in reply - I was out of the country. I've just replaced the toslink cable with a new one and everything is right as rain - thanks for the help
