Hi all,

I have recently upgraded from to, and most of the new features are great, but I can no longer get any audio from the DVD player.

I used to use the MPA codec, and this still works fine for the backup I took. But in the new version I get nothing at all from my Sony receiver. Everything is configured the same, and the graphs in GraphEdit look identical. But there is nothing.

The only way I can get any audio is to use the CyberLink audio codec, and this will only output 2-channel audio (and nothing for DTS). Selecting "Use SPDIF Output" in the configuration tool makes no difference.

Did anything change in the MPA codec between these versions? I looked in the log files but couldn't find anything obvious. I have also tried using AC3Filter, FFDShow and a complete re-install of Windows. I did manage to get some static from the MPA filter after the re-install :=)

Any help would be much appreciated.

Oh, forgot to mention that using PowerDVD I can get perfect audio every time...

    Are you using BASS as the audio engine in the Music section?

    if this is the case, try with the Internal Dshow player selected.
    Then i'm sure it will work again.

    if it works and you want to use BASS as the audio engine, please do the following:

    Please make a backup of your current folder, so that you may revert back to the original release.
    Then grab a SVN build

    try with this.
    I've fixed a problem there in the last days.

    Thanks for the suggestion. I was using the BASS engine, but setting it back to the internal dshow engine didn't work.

    I was noticing some strange behaviour when viewing the DVD playback graphs with Graphedit last night. It seemed to be selecting the DScaler audio decoder no matter what I had selected in the configuration tool. The actual decoder I had selected was on the graph but disconnected. Probably not relevant but I thought I should mention it.

    I'll try that SVN anyway though.
