My laptop is acer nitro 5 an515-55. I notice that when I turn on my external monitor, the sound disappears. My monitor uses HDMI cable to connect to my laptop.


I checked playback devices and I can't see realtek(my audio driver.)



The only way for me get the sound back is to restart my laptop but I don't want this to happen everytime.

Any help is greatly appreciated. Thanks.

    Hi,
    Give this a try, highlight KA242Y in Sound control panel, click Set Default and click Apply.

    @brummyfan2 I already tried that and it still disables realtek hd audio manager when my external monitor with HDMI cable is turned on.

    Currently, I am observing turning off the audio via NVIDIA control panel.

    Does anyone know what else can I do? The problem still occurs on my laptop even though I turned off the HDMI audio on NVIDIA settings.
  • When you connect the monitor, do any settings appear here?
