Following from a previous problem, I’ve upgraded my old optically connected sound bar with a new HDMI connected unit. It generally works well, except when I try to play a video file with Dolby 5.1 sound through the Vero. In that case, I get no sound. This did not happen with the old unit.
My system settings are as per the OSMC instructions. Other sound codecs work.
There’s a work around, though. Start the video, long press the menu button to bring up the audio display, and toggle the pass-through button off and on. Audio comes on when pass through is turned off, and stays on after a short pause when pass through is re-enabled.
I have two Veros. They both display this behavior, except that the other Vero produces noise before you do the pass through toggle trick. My second Vero has been connected to an HDMI sound bar for some time and I haven’t noticed the problem before, although it’s not used to play movies very much.
One other thing. The new sound bar reports ‘No Signal’ when the problem occurs. Video display is normal.
I’m traveling over Christmas / New Year (negative PCA test willing) so only have tomorrow (GMT +11) to play with the system if you come up with something. Otherwise, enjoy the festive system and we can take it up next year. Thanks for your support over 2021.
I think the confusion here is that when you look at the logs it shows AC3 transcoding as being enabled but in reality the setting doesn’t actually get enabled unless you have your channels set to 2.0 (thus why it gets dimed in the UI for all other channel count settings).
As for the issue, not sure but I would enable Dolby Digital Plus in the passthrough settings and see if that makes the problem go away.
I’m away for two weeks so it will have wait until I get back.
I had the transcoding enabled for my old sound bar. Had I play with the settings before I left, and noticed if I reverted to 2.0 channels, transcoding was still selected. I deselected it, reverted back to 7.1 channels, but it didn’t fix the problem.
I’ll resurrect the issue when I get back. Thanks for the assistance so far.
Well, I’m back from my holiday and spent some time playing around with the Vero audio settings to see if any affected the behaviour I’d observed regarding videos with Dolby 5.1 audio.
I’ve found the culprit setting.
When I replaced my old optically connected sound bar with a new one with an HDMI interface, I changed the Vero’s default audio interface setting, ie, the one that allows HDMI, optical and analogue connections, to HDMI only. (The first setting at the top of the audio configuration page.)
I’ve found that if I change this setting back to default, the problem goes away.
It seems that the HDMI only option affects playback of pass through Dolby 5.1 audio.
Is there an issue with the Vero software that deals with this option? I’ll leave that one to the experts.
