  1. Audio suddenly swapped from speakers to monitor. PC no longer recognizes speakers and...


    On August 26, 2020, my PC audio suddenly swapped from my speakers to my monitor. My PC no longer recognizes my speakers or headphones, and sees my monitor as the only available audio output.


    I'm trying to boot up the Realtek Audio Control app to troubleshoot my audio issues but I'm met with "Can not connect to RPC service".

    Looking online I found that I had similar issues as highlighted in this forum post. I tried following the directions listed by Peer_Sam, but when looking at the list of local services he mentioned, I found I was missing "Realtek HD Audio Universal Service". I suspect that this is a driver issue to do with Realtek because when going into Device Manager, usual Realtek audio software that I have isn't there.


    This issue has happened before, around April of this year, it lasted around a month and a half before automatically fixing itself.

    Monitor and speakers

    When you connect any pc with a hdmi monitor that has built-in speakers via hdmi cable, the pc will pass audio through the hdmi cable to the monitor. It is the Intel display audio driver or the nvidia audio driver that is doing the job. Realtek audio drivers have nothing to do with it.

    When you plug computer speakers to the back of the pc's 3.5mm audio speaker port, you have to set your default speakers to realtek.

  3. HDMI monitor audio out no longer recognized

    Monitor: LG 34BK650-W 34" WFHD 2560x1080 connected using HDMI

    Windows 10

    Before 5/12/2020 update my monitor was recognized as an audio output device and I could toggle between my monitor speakers and headphones in the playback device menu. After the update, my monitor speakers are no longer recognized and I'm not sure how to
    fix it.

    I have tried restarting my computer and unplugging the monitor.

    Thanks for your help!

    Monitor and speakers

    Hi,

    You are right sandyt *Wink

    - Monitor internal speakers via HDMI/DP use the audio drivers from GPU/iGPU audio codec
    - Speakers via jack 3.5mm port from monitor use the audio drivers from GPU/iGPU audio codec
    - Speakers via jack 3.5mm port from rear/front of your PC use the audio drivers from MB audio codec

    So the ideal D33ha would be that you do that : Monitor internal speakers via HDMI/DP & speakers via jack 3.5mm port from rear of your PC, then you switch from one audio playback device to the other via the Windows volume tray icon
