Unfortunately this may simply never work. Not all PCs actually support hdmi audio and there are frequently signal compatibility issues with these off brand TVs like tcl. What you can try though is going into the pc audio settings via the speaker icon on the task bar. Right click that and go into the mixer/output options and set it to hdmi audio rather than pc speakers or headphones and see if that helps.
