Screen shut down changes audio device

Question

Hi

I have a Dell U2412M and have the screen shutdown set to 10min. in windows 7. Listening to music through HDMI to an Yamaha RX-V373 Surround Receiver the sound changes to pc speakers, whenever the screen shuts down for power saving. Does any of you know, how to keep HDMI as audio output?

Any help would be greatly appreciated.

Best regards

Jannik

All monitor sound circuits are off when the monitor enters power save mode or if you manually turn the monitor off. There is no workaround for this. The monitor must be on for the monitor sound to work. When you allow the monitor to enter power save mode, the operating system senses this and enables the PC sound card.

Hi Jannik,

You may try to set the HDMI as default audio device.

Click Start, and then Control Panel. Select the Hardware and Sound category.
Click Manage audio devices, listed under the heading Sound. In the window that opens, a number of devices may be listed under Playback.
Among the listed devices, select the device described with HDMI or Digital Audio, and click Set Default. A green tick mark should show that this device is now the selected output device. Click OK to confirm and close the window.
The audio should now play back via the HDMI output.

Hope this helps.

Hi Fusion

Thank you for the reply.

I do that every time and the sound is going through the HDMI al right, but after 10 minutes, when the monitor goes into power saving mode, the sound starts coming out of the PC speakers. Then when I touch the mouse for example, to turn the monitor back on (out of power saving mode) the sound goes back to coming out the HDMI.

hanseivan, That monitor is acting correctly. When the monitor is off, you will not get sound.

Thanks for the reply, Chris. But there is sound from the PC speakers. Why does the computer change audio device, when the monitor goes off?

hanseivan · Answer

When turning the monitor off manually, the sound keeps coming out the HDMI. Then waiting for windows to make monitor go into power saving (still with it manually off), the sound goes to PC speakers again.

Does any of you know a workaround for this?

I guess turning power saving off the monitor would do the trick and just turn it off manually when listening to music. Or using 3.5 mm connection from PC to receiver or get a stand alone audio card. Would that work with watching movies on the HDMI too, for better audio quality?

That made me get it! Thank you for explaining it so concise. :-)
