This might be a silly question.

But all this time i've been filming in 24p and just now I switched to 50p ... but noticed I get no sound at 50p but at 24p my microphone picks up sound like it should???

Any ideas?

EDIT: I have double checked my settings etc. As soon as I switch from 24p to 50p and record, I get no sound, just a fuzzy noise if I put the volume really high whilst playing it back on my PC. But at 24p everything is as it should be ...

Not sure what you mean, you say you don't have sound but your mike does pick the sound up? Do you mean you don't get sound when you playback in your NLE?

Ok, if I set the camera to 24p.

Press record ... start talking while recording. Then playback this file in my NLE it plays perfectly with sound of me talking.

Now, switch to 50p Progressive. Start talking whilst recording. Then playback this file in my NLE I have no sound other than a hissing noise, which mind you can only be heard if I put the volume up on the PC to nearly full.

It's as if the camera disables audio automatically when you switch to 50p

Does your nle support 50p avchd 2.0 files?

Yep ... my VG20 50p files playback fine.

And it's not only in the NLE. Just in general when I open the file using VLC Media Player. No sound in 50p but sound in 24p

That's weird, and if you playback the file in your camera, do you get sound then?

Noa

It plays back fine on the EA50 ... with sound like it should.

But in VLC and Sony Vegas it doesn't ...

Does the VG20's 50p use the same codec as the EA50?

It definitely must be the computer then.

Fixed the problem.

It was a software issue. Not a camera problem (thank god for that ...)

Usually it's a codec issue if you get sound on the camera but not the pc, good though that you got it solved.

Also. Some software cannot cope with LPCM audio in 50p mode. If you change your setting to anything other than 1080 50p, or you change your audio to Dolby Stereo instead of LPCM, it will be fine.

This comes up all the time with these new 50p pro cameras, it's been mentioned a few times on these forums.

e.g. Premiere Pro CS5 didn't do 1080 50p with LPCM audio, CS6 does.

Sony Vegas plays it back fine. VLC Media Player & Windows Media Player doesn't ...

It's easy to forget as you upgrade your camera, your PC usually needs to be upgraded too!

Yep! I freaked out when my first filming with my Sony NX70 appeared to have no audio... lesson learned the hard way!
