Hello all,

I thought I'd make this a seperate thread as I've resolved a lot of the issues I was having with the DVB-T broadcast. I've set up GBpvr and its working great. EPG is coming though as pictured below.

The video is working ok as well. But I'm still having audio issues.

I've heard that some channels (1 and 2) use AAC while others require the monogram codec. I've tried installing monogram but it always fails by itself, I've also tried codec packs which supposedly have them as well. So far I don't get any audio on any channel.

I've included the settings that I use for playback currently:

The question becomes, what settings do I need. Any ideas for the audio codec? Are there any install instructions for the monogram one?

I have been exchanging information with sub on similar issues. I could not play any .ts files using gbpvr until I applied a patch and turned off some setting in config.xml. Looks like you've done that.

But I cannot get any audio from a file that uses the AAC LATM codec even though Monogram is installed and registered. Check out the following thread:

From reading posts 19 and 20 it sounds like the Haali splitter might not be compatible for the Monogram codec. I also tried HDTV Pump but that just causes WMP and gbpvr when trying to play any .ts file.

Might be SOL until sub fixes it

You should be need to copy the monogram aac file to a directory such as \windows\system32 and then register it. Have you done that?

The GB-PVR config.xml file contains a reference to the H.264 aucio decoder that the GUI doesn't have, check that and make sure it is set to MONOGRAM AAC Decoder

I figured out that I had to run command prompt in administrative mode to register the file. Thats installed successfully now.

I've opened up gbpvr and made a few changes there. No audio yet - but am restarting the machine anyway.

I've included part of the config.xml file - am I missing anything?

Update: I can get audio if I start a recording and watch that recording even while its recording... but live tv results in no audio.

If you post the logs over at the GB-PVR forums I'll take a look.

At a guess though, if you had GB-PVR installed prior to the recently released v1.2.9, did you follow the instructions in the release notes with 1.2.9 to recreate your capture source and rescan for channels? This is required because new information is collected about the audio format of the AAC channels. If you hadnt done this, the information will not available, and it'll result in no audio for live tv.

I just put the directshow filter in windows\system32 and from the command prompt did regsvr32 whatever.ax (can't remember the name)

Since there is no choice on how to use this filter (other choices for AAC LATM) I think I recall reading on the gbpvr forum that sub has not provided a drop down list to select it. If registered it will be used.

And I do have the setting for the filter in my config.xml file. I think my problem is the Haali Pump filter not possibly being compatible with the Monogram filter.

Its important to note that the our discussion about the haali spitter etc on the GB-PVRs forums (not the thread linked above) was in relation to your Telstra Clear transport stream files, which resolved an entirely different problem (audio sync issue playing transport stream files). The Haali splitter will work fine with TelstraClear MPEG2 transport stream files. It wont work with AAC LATM audio.

DVB-T with H.264 and AAC LATM audio is an entirely different kettle of fish. With the appropriate decoders installed, you should be able to get live tv with audio in GB-PVR. You can also make bit perfect recordings. There is currently an audio/video sync issue when playing back those recordings, which I'm looking into.

My post above will answer the question about the Haali splitter and lack of audio. You can switch back to using GB-PVR's built in TS reader filter, which does support AAC LATM, but it can have audio/video sync problems in some circumstances. I'm looking into this. This component is only a few weeks old, so still very new, and a few kinks to iron out.

If you're missing audio with live tv, then post the logs over at the GB-PVR forums and I'll take a look.

Yes it started with the TCL ts streams which you solved for me but then having done that I thought I would try the HD streams. So it sort of followed but I am guessing if I could not play regular .ts streams then audio or not I would not be able to play the HD streams. Will try out your suggestion about turning on internal support for ts streams since I decided that I didn't need the Dreambox I had borrowed and won't really be getting anymore MPEG2 ts streams unless I go for a DVB-C capture card which I presume produces the same type of files the Dreambox does.

Sorry to take over the thread, but does this explain why i have sync issues when i have a client setup to get live tv via "file sharing"

"Streaming" doesnt seem to work just end up with a blank screen

The client/server support currently only supports .mpg files. I'm sure surprised you had any luck with .ts files. I've never once even tried .ts files in client/server mode. It is on my list of things to look into in the future.

Yep, no worries - I guessed this from your post here, but I wanted to make it clear why this was incorrect before everyone starts installing haali splitter etc to try to get H.264/AAC LATM working (which wouldnt work). This stuff is pretty complex, and mixing the facts up can make it more confusing for people.

Thanks - I started off with 1.2.9. Just readding sources now as a sanity check (having issues picking those channels back up) but will give it up a go...

I've done a full reinstall and made sure that monogram was selected. It appears to be working, despite the config looking the same.

I do get the odd time where I lose audio but changing channels appears to resolve it. I'm going to keep going and if I get any instances I'll post the logs.
Thanks sub for your pointers :)

Edit: mainly seems to be pausing, rewinding, fast forwarding.
