  • Using dual S2719DGF monitors with PC and audio output to external speakers. I could control volume fine on windows, and when I wanted to connect a game console or something I’d just lower the volume with the OSD on one of the monitors (As the external speakers are fixed volume.) I connected my mac to these monitors via DisplayPort and wanted to be able to control the volume through software, so I downloaded MonitorControl for MacOS, which controls brightness and volume over DDC (display data channel.) Both worked excellently. Changed my setup and used HDMI from mac to monitors, and I noticed volume control was no longer working. Not only that, but volume control with the OSD didn’t work universally… volume is now stuck at 100. Even disconnecting all display cables except one connected to my Switch proves that volume control is still not working. Did controlling my monitor volume over DDC kill the volume control? Anyone have any ideas on what I should try?
