I am using a Floppy DTV with Cam for an french operator: canalsat, The TV engine work almost fine.
But some channel don't have any sound...
In first time I think it's an AC3 decoding problem but we are using SPDIF output, so my computer do not decode the sound, it's the Home Cinema...
And some channel with AC3 are working well...
I try do decode the sound with ffdshow, discaler dodec and MPA but all the same some channel don't have any sound ...
I try to read the log files to found the error but I didn't see anything ...
I attach to this post some logs files .. if someone had an Idea...

PS : I test also with the TVEngine3 and I have the same problem

I post the problem on the official forum of "FireDTV Support" : http://www.firedtv.com/Forums/tabid/311/forumid/17/postid/2301/view/topic/Default.aspx

Like they said : A quick check on Mantis does indicates other people that have reported a bug on something that looks similar: http://mantis.team-mediaportal.com/view.php?id=771

Her conculsion is : " it does appear to be an issue with the stream support in MP".

So could you help me ? I post my graph if it can help :

For graphedit, i test graph with a channel with sound and with a channel with no sound. There are no difference :

Have you tried using different audio codecs?

 

[RutgerDB]

I have the same problem. I have tried numerous Audio/Video codec combinations to no avail. I'm using Alphacrypt cam + FireDTV with Irdeto smartcard.

Digital radio is broken and Eurosport / Motors TV and some other channels don't produce any sound. When searching thru my logfiles all looks well, no errors are logged.

When I put the smartcard in my Samsung decoder audio is just fine.

I find a solution to my problem. With Graphedit, I see that the problem come with the MPA/MPV codec. I uninstall them with the command :

regsvr32 /u MPeg2DecFilter.ax
regsvr32 /u MPaDecFilter.ax

And now I can select ffdshow to decode my audio stream and I have sound with all channel
