JR TV Will not play channel audio if AC3 anymore [Solved]
« on: December 12, 2020, 07:07:36 pm »
Hi Folks, Dave from Aus here... I am trying to diagnose a problem that appeared around the same time I updated to version 27 in mid -Nov. I didn't notice for a little while. The TV channels that play audio in AC3 mode (usually the HD version of standard channels) will output audio, while the standard channel play audio no problem as MPEG-2. Note nothing else in my hardware has changed. It is clear it's not DAC problem, because according to DSP the audio from the TV tuner in AC3 is not even being processed by JRiver see pic.

I need some ideas to diagnose what is going on here. I am pretty sure before this I have notchanged any settings in TV section for a long time. It is not a DAC or windows issue because the audio originates inside JRiver using the TV Tuner card and it's not getting out! When I play standard channel in this case MPEG-2 it behaves as expected. Note I am not trying to watch this particular crap program - but fix it for when something decent is! :-[

Bump... No joy here, anyone have any ideas? I can no longer hear Free to air HD channels. I have re-tuned / config the devices - still the same?

There have been a few channel changes here in Oz, so it may just have been a coincidence that you noticed the problem after the upgrade.

I had to rescan all my channels a while back to get them all working correctly again, with the correct audio. SBS with two audio streams was an issue, which I had to fix manually, selecting the correct PID, for example.

Hi folks - this has been resolved now. The problem is I am not sure sure how I fixed it or why it occurred in the first place. I had retuned the stations already prior to this. Very odd. Thanks for the assistance though.

Further update: I have replicated this behaviour and it relates to turning off bitstreaming. If I turn off bitstreaming in settings which is recommended everything works except for these TV channels broadcasting in Dolby AC3. Turn it back on to S/PDIF bitstreaming the Channel passes back through the DSP and operates as expected. So it seems I cannot use the recommended settings if I want to watch certain channels on TV through JRiver - which is fine now I understand what is happening I just switch zones one set up to decode in my DAC, the other setup to provide analog output.

Thanks

Probably your Output Format (in DSP Studio) needs tweaking.
