I've had an issue with an Inspiron 7786 and have the issue with unplugging headphones and then losing the ability to plug them back in.  It has always been quirky with other Dell's and headphones so I have to reboot.   Did you have any luck with finding a solution?
In September a new Realtek Audio Driver was posted on the website, version 6.0.9228.1. I downloaded this driver because in the release notes a bug related to detection of headsets was solvedand I deployed this driver to all our Latitude 5320 - 5520 portables (100+ devices) Suddenly the driver was removed for download and when I looked into the event viewer of the Dell Latitude 5320 - 5520 portables, I saw a lot of audiodg.exe crashes. Some computers having crashes every hour. I pushed a new package to force the installation of the previous Realtek Audio driver, 6.0.9126.1 which is now offered again on the Dell support site for the Latitude 5320 - 5520 portables and the driver has been downgraded on the computers. One big issue: the Waves files are not downgraded and are still using the executables and libraries from the removed audio driver. This causes the crashes to keep happening. C:\Windows\System32\DriverStore\FileRepository\wavesapo10de.inf_amd64_7737a334c51065aa\ These files have a date of 20/08/2021 while the previous driver, 6.0.9126.1 contained files dated 5/11/2020. How can I force a downgrade of the Waves application? (WavesAudioService.exe, WavesSvc64.exe)Or when will a new update released so I can upgrade the Waves application? For the downgrade (which includes Waves in the installation package) I used the following installation command:DELLMUP.exe /S /v"FORCE=true" Thank you for your clarification!
