I reviewed your post and I understand that you are not getting audio from the TV when connected through the HDMI cable.
Don’t worry, I assure you I will try my best to get this sorted.
What options do you get when you click on the speaker icon on the bottom right of your computer? (When connected to TV)
Meanwhile, I recommend you update the BIOS, graphics driver, and audio driver from the below link and check if it helps.
BIOS: https://ftp.hp.com/pub/softpaq/sp110501-111000/sp110841.exe
Intel: https://ftp.hp.com/pub/softpaq/sp108501-109000/sp108998.exe
Nvidia: https://ftp.hp.com/pub/softpaq/sp108501-109000/sp108996.exe
Audio: https://ftp.hp.com/pub/softpaq/sp110001-110500/sp110411.exe
Let me know how it goes and you have a great day!
