Windows 10: When I plug in my HDMI cable from my laptop to another screen, I lose my audio

The audio on my laptop works fine.

But when I plug in a HDMI cable to hook up my laptop with another screen, I lose my audio completely.

I have tried running the troubleshooter on my audio but that doesn't work.

How do I fix this?

Play Audio through HDMI cable plugged into TV

Hi,

Thank you for posting your queries in Microsoft Community.

HDMI (high definition multimedia interface) is a cable connection that sends both the HD audio and video signal between HD equipment. If your laptop computer has an HDMI input connection installed, it is possible to play the audio of an HD device directly
through the laptop computer's speakers. Doing so doesn't require any additional equipment, except for an HDMI cable.

Plug the HDMI cable into the "Out" port on the device you want to send the audio signal from (such as an HD audio receiver or even a high definition television set).

Attach the other end of the HDMI cable to the HDMI connection port on the laptop computer.

Double-click the audio icon in the lower right corner of the laptop. Make sure nothing is checked off under the "Mute" option.

Play the audio from the original source device and the HD audio will play through the laptop computer system.

I hope this helps you. If you have any further query in future, feel free to contact us. We will be happy to help you.

 

Play Audio through HDMI cable plugged into TV

Thanks, but that's the opposite of what I asked. I have a desktop and am trying to play sound through the TV, using the HDMI port. Works for my 360, haven't seen the digital audio device option on my Windows 10 platform.

 

Laptop display and monitor will not wake when HDMI cable plugged into laptop.

I have a laptop. Lenovo ideapad FLEX 4-1480 Signature Edition.

The laptop has a display, and the laptop is connected to a monitor via an HDMI cable.

Sleep mode is disabled.

Screen timeout is enabled.

I lock the computer. The laptop display and monitor both eventually deactivate.

I move the mouse and press keys to wake the monitor. Nothing happens on either the laptop display or the monitor.

If the HDMI cable is not plugged into the laptop, the laptop display will wake as intended. The problem happens only when the HDMI cable is plugged into the laptop.

I have to remove the HDMI cable from the laptop, wait a few seconds, reinsert it, then the laptop display and monitor will wake. Again, the laptop display will wake just fine when the HDMI cable is not plugged in.
