Hello. I've got a HV30 and I recently bought a basic generic microphone (yoga EM-288) to plug into the mic socket. It has the correct battery and is switched on.
However on the camera's LCD there is a message saying the audio is switched off. When I disconnect the mic the message goes and the internal mic takes over and when I play back the film there is no sound using the external microphone.
The microphone itself seems to be alright as it can record through when connected as an input into the PC.

I've also tried connecting a mono speach mic to the camera but the same thing happens. There is a message saying the sound is off and when I playback there is no audio

Have I done something wrong or do you think the camera has a fault?
