I can't hear any sound on AVex

The audio is muted during DVD/video recording or converting, if you can't hear any sound during recording/converting, that's normal. However, if you still can't hear audio of the output file, there's something wrong with your audio codec, or some incompatible problem between your video and audio codecs. Don't panic when you have this problem, it can be resolved as described below:

1. Upgrade to DirectX 9.0c. Download and install MpegDecoder-1/2, AC3Filter, and choose "Microsoft DVD Navigator" as DVD navigator, MpegDecoder012 as DVD Video Decoder, AC3Filter as DVD Audio Decoder in the "DVD Settings" dialog.

2. If you're using the AVex Video-Only Converter(inlcuding AVex iPod Video Converter, AVex iPhone Video Converter, AVex Apple TV Video Converter, AVex Zune Video Converter, AVex PSP Video Converter, AVex 3GP Mobile Video Converter, AVex Video Converter Platinum), there won't be any "DVD Settings" in "Options" menu. You need to:

(1) Download the K-Lite Codec Pack, if the link doesn't work for you, download it at: http://www.free-codecs.com/download/K_Lite_Codec_Pack.htm, and install it on your system

(2) Click windows "Start" menu -> "All Programs" -> "K-Lite Codec Pack" -> "Tools" -> "GSpot Codec Information"

(3) Click the pink button " ... ", select the original video file(s) to be checked

(4) At the bottom of GSpot program, click the pink button "1" under "MS A/V", the GSpot program should display the audio filter and video filter used by the original video file, e.g.:
Render OK; the following combination of filters was used:
(Src)-->[CoreAVC Video Decoder ]>--(A)-->[Video Renderer ]
(Src)-->[ffdshow Audio Decoder ]>--(A)-->[AC3Filter ]>--(B)-->[Default DirectSound Device]

It's possible that the original video file can't be rendered by the GSpot program, it will probably prompt the error message as shown below:
Warning: DirectShow Crashed while attempting to render this file
This is usually due to damaged, misconfigured, conflicting, or poorly written codec drivers. It is possible, perhaps even likely, that other media players will crash when they attemp to play this file as well, as most of them will also use DirectShow. Although GSpot was able to intercept the crash, attempts to identify the codec which caused it have failed. Unfortunately, no additional information is available at this time.

Please don't panic when you see this warning. You can uninstall your Xvid codec, restart, reinstall Xvid Codec; or uninstall and reinstall your ffdshow codec. Meanwhile, apply this uninstall and reinstall process on your Graphics Card Driver and DirectX 9.0c.

(5) In Step (4), if you're able to read the audio and video filter:
(Src)-->[CoreAVC Video Decoder ]>--(A)-->[Video Renderer ]
(Src)-->[ffdshow Audio Decoder ]>--(A)-->[AC3Filter ]>--(B)-->[Default DirectSound Device]

uninstall the ffdshow and AC3Filter, or whatever the audio decoder and video decoder shown on your GSpot program, restart your system when possible. Then you should be able to no audio problem.

3. If you have installed PowerDVD 5 or above, WinDVD 5 or above, you should uninstall these DVD players, which will uninstall the video decoder and audio decoder coming with the DVD player. Then reinstall PowerDVD or WinDVD. Then open AVex program, go to menu "Options", click "DVD Settings", modify the DVD Setting as any ONE of the following Combination, but don't mix them up, e.g., don't mix Cyberlink Audio Decoder with Nero Video Decoder:

* DVD Navigator: Microsoft DVD Navigator
Audio Decoder: AC3Filter
Video Decoder: MpegDecoder012
* DVD Navigator: Microsoft DVD Navigator
Audio Decoder: Cyberlink Audio
Video Decoder: Cyberlink Video Decoder
* DVD Navigator: Microsoft DVD Navigator
Audio Decoder: Intervideo Audio Decoder
Video Decoder: Intervideo Video Decoder
