Sighz, this is very frustrating!! I have posted no less than 3 posts over 40 days at both mythtv-dev and mythtv-users asking about software AC3 decoding and got zilch replies. I searched the gossamer threads using various search combinations but found no answers. I had patiently waited for some kind soul to shed some light on this issue but none came forward.
Can somebody please, please tell me whether software AC3 decoding support is working in Myth in the first place? i.e. when the audio stream is in surround sound, decode it inside the computer and pass out the 5.1 channels via the sound card's 3 analog outputs. I have surround sound in MythVideo, but not when watching live HDTV. Whenever I set a surround sound APID in my channel info, all I hear are cracks, snaps and pops over the 3 analog outputs (note, I am not using the DVB 2.1 patch for this). Is this feature lacking in MythTV itself, or is it because of some configuration error that I've made? Is surround sound part of the DVB patch? As mentioned I am more than willing to try and implement this feature, still it takes time for me to understand how sound is implemented in Myth, so I welcome any help/tips/suggestions to point me in the right direction. Again, say something to me - abuse, flame, curses, anything to put me on the right track. The community help for MythTV is amazing, but somehow lacking when it comes to surround sound for TV, sighz.
