ever now and again it'll start "hissing"
If you turn it off and back on the hissing will stop.
I havn't had the keyboard long, and i was just wondering if there was something to turn it on?
if you plug headphones in, the right side doesn't work either

I fear thats it's a dodgy sound card or something?
but just wanted to ask incase there was something simple im missing?
Thanks
