    Problem
    Realtek Audio Driver doesn’t dynamically switch between PC Speaker and the Headphone Jack in Windows 10 1903

    Symptoms
    1. Sound plays through the PC speaker, if you plug in headphones the sound continues to play through the PC speaker
    2. If you restart the computer with headphones plugged in, the sound plays through the headphones. When you unplug the headphones, sounds play through the PC speaker. When you plug the headphones in, the sound continues to play through the PC speaker
    3. If you plug in the headphones early during the logon process, sound will play through the headphones. If you unplug the headphones after the logon process is complete the sound will play through the PC speakers. When you next plug in the headphones, the sound continues to play through the PC Speakers.

    Root Cause

    The Realtek audio driver installs a service called 'Realtek Audio Universal Service' 'RtkAudUService64.exe' that is instructed to start up in three contexts.

    The Service starts up as automatic in the system context and spawns two processes

    "C:\WINDOWS\System32\RtkAudUService64.exe"

    "C:\WINDOWS\System32\RtkAudUService64.exe" –admin


    And the following registry entry starts it in the user context

    KeyName

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

    Value

    RtkAudUService

    Data

    "C:\WINDOWS\System32\RtkAudUService64.exe" –background


    The Service in the User context seems to break the dynamic switching or recognition of the engagement of the headphone jack.

    Workarounds
    1. 1. Kill the Process (Standard User)

    · Open the Task manger by right clicking on the task bar and selecting the 'Task Manager' from the context menu.

    · Click on the 'Details' Tab

    · Sort the processes by Name if necessary.

    · Scroll down to the 'RtkAudUService.exe' entries.

    · Select the 'RtkAudUService.exe' entry that has your username represented in the 'User Name' column.

    · Either Right Click the process then select ‘End task’ from the context menu, or Click on the 'End Task' button at the bottom right of the 'Task Manager' window.

    · Now logoff and log back on or reboot the computer.

    3. Delete the Registry Key (Administrator)


    · Open the Registry Editor by pressing the Windows Start Menu and typing 'Regedit' then selecting the resulting option.

    · Navigate to 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run' and select the 'Run' Key

    · Right Click the 'RtkAudUService' entry in the results pane and select 'Delete'

    · Reboot the Computer

    NOTE

    I have only tested on Windows 1903 and only noticed the problems with the 'Realtek HD Audio universal Service'. This is installed on a driver that is used in many Dell models and HP laptops. I don't seem have the problem on computers where the Startup Service is called 'Realtek HD Audio Manager'

    Realtek HD Audio not switching to Headphone settings


    My case, Antec P280, has an HD Audio front panel, and the motherboard is configured for HD Audio.

    It still detects when I plug headphones in, and I get the Realtek popup asking me to confirm that I plugged headphones in and whether to use the Auto, IEM, or Full Size headphone setting. But then it stays on 5.1 Speakers in the Realtek HD Audio Manager, and in the Windows device settings.

    If I plug headphones in via the front, the Realtek Audio Manager detects the headphones and mutes the rear jacks, but stays on 5.1 Speaker setting. Clicking on the pictures of the 5.1 speakers causes every speaker except the sub to play via the headphones.

    If I plug the headphones in the back, in place of my front speakers, and click on the output jack to switch it to Headphones within the Realtek Audio Manager, it still stays on 5.1 Speaker setting and only the front speakers play via headphones.

    It used to work fine, and I haven't made any hardware changes in the last few weeks.

    Could it be that the recent drivers have disabled the separate Headphone setting entirely, and it's now always whatever Speaker setting you specify?

  3. Audio jack seems not detect my headphone


    I have a windows 10 laptop and up until yesterday everything was fine , and suddenly it seems that my audio jack doesn;t detect my headphone. I connect my headphone to the audio jack, but the sounds just came out my laptop's speaker. I've tried to switch to my earphone and the result is the same. I've tried several solutions like uninstalling my driver or trying to get to the sounds properties , but the results are the same. Please give me your help , and btw I'm new here.
