I’m using Infuse as a replacement for the new TV.app on the iPad, as it no longer supports continuous playback. I synchronise all of my content manually from iTunes for Mac via USB, so all the content I’m viewing in Infuse comes from having “Show iTunes Videos” selected (there is no content, otherwise).
Some programmes (that play fine with audio, when using the TV.app) don’t have any audio on Infuse. I think this is all the content that I have ripped from my own DVDs (using Handbrake), since downloaded content plays ok with audio.
The ripped content says it is “H.264/MPEG-4 part 10 480p AAC” and when I check the settings and the audio tab, it just says “Audio tracks: None”.
Where has the audio gone from these? Like I say, they play just fine when using the TV.app.
