HD stations no audio (1 Viewer)

[Nightmare77]

Just wondering if there is a fix for the no audio on HD stations for aussies with dvb-t? Or is it working for other people?

Are you using the TV Server with a local MP Client or streaming to VLC? I have HD with AC3 on mp client if I use the Cyberlink PowerDVD7 decoder rather than the MPV decoder.

I'm having problems with HD Audio from TV server with Australian DVB-T as well. Could it be something to do with AC3???

i was thinking it was AC3 as well since i can think thats probably the main difference in the stations. The odd thing was one time i did get audio on the station but then i lost audio on the SD stations. So perhaps it is a codec thing and i should play around more with it.

I found that if the first channel I go to is HD then audio for all HD channels will work but for all SD channels audio will not work - and visa versa - i.e. if the first channel I watch is SD then all SDs work but audio on all HDs doesn't work. If I turn TV off and on it seems to reset... weird!

hmmm i haven't managed to get my working this way , the strange thing is if i set the channel to say WIN HD then use VLC to receive the stream i get audio in VLC. but if i were to close that down and load MP client on the my htpc i dont' get the audio still, does anyone thing i need to install ac3 filter or some other codec?

Regarding the different networks & programs in AU, some SD programs are supplied with mpeg and ac3 audio channels, some just supply a single mpeg audio channel. For HD they just supply an ac3 audio channel. Since the TVserver re-stripes the transport streams using the existing sub streams you can get a mix between mpeg, mpeg/ac3 and ac3 only streamed. If the TVserver switches between SD only channels then you will get a consistant mpeg audio stream and hence the client plugin should not have problems playing the audio. When the TVserver switches between an SD and a HD channel then the same stream pid value is used by the TVserver so the player still expects to see the same audio stream type, hence you get no audio. Hope this helps to explain what your getting.
