Hi YoungBuck,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP ENVY TouchSmart m7-j020dx Notebook and not working correctly with audio and the TV. Here is a link to troubleshoot the sound.
Go to the Step 2: Set default speakers and test in Figure 7 it shows the Digital Audio. Is there a check on this? If not please check it.
Hopefully this helps.
Thanks.
