Any idea where to start? I should note that the audio through HDMI does work automatically with a default ubuntu live session but I don't know how to troubleshoot and investigate the difference between that and my system. (Default ubuntu also runs slowly and the HDMI monitor won't completely fill the display for some reason, otherwise I might switch.) I tried live sessions for a few other distros and some ubuntu variants also but they all crashed when I tried to enable my second monitor.
Thank you for any help you can provide.
