I have the same problem.

Audio works fine via the browser plugin but there is no audio using VLC or Windows Media Player when playing the downloaded mp4 files.

I get the same issue... audio in playback, but when downloaded/converted to MP4 - nothing.
I have 3 ProHD 1080P cameras, model IP2M-841B, all have the same issue.

I'm sure it's something I'm doing since the audio clearly syncs in playback mode - it just won't export as MP4.
I've attempted through the native download, also through a .dav to .mp4 converter.

Please advise - thanks!
Erik

Any update? Trying to get these files sent to a client - any help would be appreciated. Thanks!

Hello all,
We have notified the developers about this issue. As a workaround, you can download the file as a DAV first then export it as an AVI in Smart Player software. This will retain the audio.

Doesn't seem that the audio carried into that format either - I'll be anxious to hear a solution. Thanks.

Hi. I am still unable to get MP4 audio in my downloaded videos despite upgrading to the latest firmware, which in the changelog states that this issue has been resolved.

I have exactly the same problem:
ProHD 1080P camera. Latest firmware.
Everything else seems to work. Can get sound in the plug-in directly from camera, but when I download a video file locally, neither .dav nor .mp4 formats have audio. I have tried Smart Player on .dav, I have tried to export .dav to .avi using SmartPlayer, I have tried to play .mp4 in QuickTimes and VLC, I have tried to play exported AVI in VLC - in all cases video works, but sound does not. (It's not a sounds problem on my Mac either - can play music and films just fine.)
Need a solution!!!

Thanks,
--Misha
