This issue has occurred for at least the last two updated. My Vero 4K+ is on the latest update (Buster). Since Buster was imminent I decided to wait till I posted this.
Anytime I watch a TV station (using a HD Homerun) through the Vero 4K I get no audio when the channel is broadcasting Dolby digital (AC3). If the channel is broadcasting AC3 (2 channel) the audio works flawlessly.
Here is the logs. https://paste.osmc.tv/atebunoqoc
I enabled logging… rebooted twice and immediately selected NBC which broadcasts the digital audio. Maybe in the logs you can see what I did.
- Started the channel NBC (6 channel AC3 with audio passthrough) and have no sound.
- Selected secondary audio channel on NBC (2 channel AC3 with audio passthrough) and have sound although my digital receiver is not decoding it.
- Disabled audio passthrough (2 channel AC3 without audio passthrough) and I still have sound.
- Selected primary audio channel on NBC (6 channel without audio passthrough) and I no longer have sound.
I thought it may be an issue with the TvHeadend Service. So I disabled TvHeadend, and installed the HD Homerun PVR. I have the same issue with that PVR as I do with TvHeadend.
Interestingly enough, when I record NBC I can watch with 6 channel audio (AC3) with audio passthrough with no issues.
