Audio Jack is not working on pc, windows 10

OK, I've solved my problem, but what was strange was the really DEEP response into all manner of software and driver checks to try and resole it: (https://answers.microsoft.com/en-us/windows/forum/all/audio-jack-is-not-working-on-pc-windows-10/fec6bd66-00a9-46d1-a86b-503af0b40070). It was actually much more simple.

How did I solve it? We all know Microsoft shoves updates outs like malfunctioning candy machine firing out gumballs...my 3mm headphone jack had stopped working as it had been somehow de-selected as a defualt output. Windows lets you select 2 defualts- built-in speakers plus another; I want to use the 3mm jack. I re-selected it as a default option and it started working again.

Why the diatribe about updates? I only ever go into settings to resolve problems (!), so all I can surmise is that a flaky update deseelcted my 2md default option as it certainly wasn't me. That or Copilot is really getting to big for it's boots...

    Hi Timbledeebobs,

    Thanks for sharing in Microsoft Q&A! I'm glad that you could resolve your issue, and what thought to be a troublesome problem was fixed via a very simple toggle.

    And I totally understand that this was annoying to deal with. It seems like the 3.5mm jack is becoming less and less favored, as it is being surpassed by USB, type C ports and wireless Bluetooth connections. That's why your device may have been de-prioritized or disabled if not actively used during the Windows update, as it can sometimes reset or change default device settings, especially for audio.

    I'd like to put a quick summary here so others can re-select the 3.5mm jack as default audio output if they encounter the same problem:

    1. Right-click the speaker icon in the system tray > Sound settings
    2. Click More sound settings > Open Playback tab (often default)
    3. Look for your 3.5mm jack headphones or line-out device
    4. Right-click it > Select Set as Default Device > OK to apply
    5. If you don’t see the device, right-click in the list and enable Show Disabled Devices

    Feel free to correct me if any of the steps wasn't like what you did. It'd help make it clearer for those who search for the same answer! Again, thanks for sharing your solution! It’s a great reminder that sometimes the fix is simpler than expected!
