I know the audio sync plugin has been removed as it was ineffective. However, two general settings remain in the AV settings menu item for AC3 & PCM so I tried both positive and negative values.
The quirk is setting either to a positive value kills PCM sound on all PCM sound channels when you change channels. Setting AC3 to a positive value kills all sound on changing channels. Negative values do not have this, or any, effect.
To confirm:
- Menu-Setup-AV setup-AV settings.
- Set the general delay for AC3 to any positive value.
- Save and exit the menu to live tv.
- Change channels - sound dissappears
- Try other channels - no sound.
- Menu-Setup-AV setup-AV settings
- Reset AC3 delay to zero or negative.
- Save and exit to live tv.
- Change channels - sound reappears.
I suggest that these two options either be removed, amended to prevent positive values or flagged as ineffective.
Cheers, Paul
