Hey there,

I'm having problems with the sound output when switching from a channel with AC3 (Dolby Digital) audio to a channel with regular mp2 audio. In almost all cases I hear no sound at all. I will not get any mp2 sound until I switch off and back on live TV. This problem started months ago, possibly with 1.0 RC1 or maybe some time earlier. With 0.2.3.0 it worked fine though.

This is what I discovered so far:
- just switching audio on a channel that offers both mp2 and AC3 audio works without problems
- the timeshift file created by TV server does have the correct audio. So the problem must be in Mediaportal itself
- as far as I could see, there were no strange entries in any logfile.
- this happens regardless of the audio codec configured in MP

I hope anyone can give me suggestions what else to try or at least confirm that there's a problem. I would really like to use AC3 sound on live TV.

Regards,
Sepp.

Use ffdshow as audio decoder. CYberlink is not the best choise.

Hi tourettes,
I tried ffdshow already, but that makes no difference. Same for MPA and the Windvd audio codec. They all show the same behaviour. So I guess it's not related to the configured decoder.

Sepp.

Hey guys,

I just tried another audio filter: AC3 Filter. But still switching from an AC3 to an MP2 channel results in no sound.

I would really appreciate if anyone could at least tell me that this works in general.

Thanks, have a good day!
Sepp.

just for information: I configured AC3Filter to encode mp2 to AC3 sound. Thus no switching from mp2 to AC3 occurs anymore. This does not really solve the problem, but it's ok for me.

I am experiencing the same issue. Any solution for this?

I have the same problem it drives me crazy

same problem here. actually, i've updated today to the latest svn and now all audio is gone, unless I use ac3 sound on some channels. the mp-system sounds are gone too....only ac3 sound still works. :s

EDIT: Damn I'm a dumb cow!
I turned down the volume of WMP while testing x264 stuff when I got a call. I forgot to turn it up again and so wasted my sunday figuring out what the hell was wrong.

same here

I have the same problem here. I didn't have the problem with Mediaportal 1RC1 on WinXP. I'm only having this problem using Mediaportal1RC2 on Win Vista 32bit using the same hardware in both instances. I cant hear anything when i play mp3s aswell, haven't had time to try avi movies yet.
