I'm did a fresh install of Generic Legacy v11.0.1 and have encountered no audio via hdmi. No issues on an older v10.0.4 on the same x86 box with Nvidia based ion hardware. This is a first where LibreELEC has not picked up the audio properly.
The audio output device is selected as ALSA: HDA Nvidia, HDMI as always in the 'Settings/System/Audio' configuration yet there is no audio at all. Sound is turned up and not muted either.
This is running on an Acer Aspire Revo R3610 that has been flawless until now.
Any suggestions?
