I was wondering if anyone knew a good material to shield the front panel headphone port. The nearby electrical components in the computer cause a considerable amount of interference. If I use a USB flash drive at the front port, I can 'hear' the data being transferred. There is nothing wrong with the headphones. I have used it with other devices and it works just fine.
Aluminum doesn't transmit magnetic or electrical fields. A lot of center channels used to be shielded using it. I mentioned it cause usually a lot of people have it for kitchen use and it's easy to work with.
