I've had my N800 for a while now and I have recently tried connecting it to my car radio using a standard jack-jack cable. To my suprise the sound I got is very hissy. The hiss is so bad that I can't listen to any speech podcasts, piano music etc. The hiss is only audible when a sound is played, for example when I click the screen and the click sound is played I can hear the hiss and then after 2 seconds there is complete silence again. It's the same when I play a music file or a film of course, I mean I get constant hiss when music is played.

There's no hiss when I connect an MP3 player with the same cable and there's no hiss when I use headphones or computer speakers so it must be something to do with the tablet itself.

The funny thing is that the only thing I can listen to is the radio. When I click the 'play' button on the radio applet I can hear the background hiss and the radio station and after 2 seconds the hiss goes away leaving me with clear radio sound.

Can anyone help please?
