I am have a huge problem with setting the "audio device" default to "stereo." My default is currently "5.1" on release 0.9.9.

When I play a DVD I can manually change the setting from the audio choice on the menu from "5.1" to "stereo" while it is playing. But I can't do this when I am converting the same DVD to MP4 format - video records fine but I get no sound and cannot change the setting manually during conversion like I can while playing the same DVD.

video records fine but I get no sound

That stereo/5.1 options shouldn't matter to video conversions because the audio device option is only for playback not for transcoding. When you transcode, you can use channels=2 to make audio stereo.

Sorry - I'm a novice. How do I use channels=2?

When you select the transcoding profile, you should see Generated stream output string, add channels=2 after ab=???, so for example if you now have change it to

Thanks for the suggestion - It doesn't seem to work

This is what the Generated stream output string looked like:

:sout=#duplicate{dst=std{access=file,mux=mp4,dst=C:\Documents and Settings\Andy Banks\Desktop\chicago 10.mp4}}

This is what I changed it to look like:

:sout=#duplicate{dst=std{access=file,mux=mp4,ab=128,channels=2,dst=C:\Documents and Settings\Andy Banks\Desktop\chicago 10.mp4}}


Is this what you meant me to do?

You aren't doing any transcoding. You cannot put AC3 or DTS audio to MP4 container with VLC. If you want to copy, use ts instead of MP4, so If you want MP4 file
