I have been having trouble with my computer soundcards ac3 output. I have a via envy24ht-s PCI soundcard. The sound card claims to be capable of outputing AC-3 realtime but my AC-3 decoder will not recognise the signal. But the decoder will recognise AC3 from a DVD. Is there a known difference between the AC-3 signal from soundcard that would be encoding realtime and AC-3 sound from DVDs? Any suggestions on how to get it to work? Thank you in advance for any help.
Hello, I have the same probleme. The DVD AC3 signals are not recognised by my amplifier's decoder. In my case the DVD DTS is recognised by the amplifier's decoder. I've got a Juli@ sound card and a Yamaha DSP-A1 amplifier which seems not to be compatible PCM encapsulated AC3 signals. It is that kind of signals the could come out of the sound card... I found a link to find out if my amplifier/decoder is compatible and it is not! http://www.linuxtv.org/vdrwiki/index.php/DD_receiver Does someone know howto produce "pure" AC3 signals without PCM encapsulation in Envy24ht-s PCI soundcards?
