Hello AlexHPinFL. Thank you for posting on the HP Forums. I understand there is no audio through an HDMI connection. I apologize for the long response, but I will do what I can to provide a stable response. First, I have some questions I need to ask, which will hopefully narrow down the issue:
1. Was this function working properly in Windows 8? If this never worked, regardless of the operating system, please let me know. Also, let me know if it stopped after some random occurrence.
2. The title seems to imply that there is no audio when connected to a television, using HDMI. Does this only occur when you connect to a television? Will it occur if you connect to something else using HDMI?
3. Have you tried connecting to a television using VGA or DVI? If so, what are the results?
Please respond with this information. Additionally, I require the complete model number of your Envy computer. If you require assistance locating this information, please reference this website: Locating the Model Number of the Computer
As soon as you respond, I can assist you thoroughly. Thank you for bringing your issue to the HP Forums. Have a great day!
Mario
