XPS

I just got my new XPS 13 Plus laptop in the mail a couple days ago. Everything was great on the computer until I ran into a sound problem. I connected my bluetooth headphones to the computer. No problems occurred when connecting and listening with my headphones. The problem is when I disconnected the headphones and now I do not have any sound. I would consider my self as a pretty tech savy person, so I went through the process of troubleshooting and could not find a solution. I read some other forums on the Dell website with the same issue but not solution.

I had a similar problem and discovered that the internal speakers would no longer work if I had 'Enhance Audio' switched on. 

Go to 'System' -> 'Sound' -> 'Properties' (or Speakers, Intel Smart Sound Technology for MIPI SoundWire Audio etc) and you should see an option for 'Enhance Audio'. Switch this off and hopefully, your internal speakers will work again. 

Strangely if 'Enhance Audio' was on, I could hear sound from Bluetooth headphones or external speakers without any problems.

For me, the problem occurred even though 'Enhance Audio' was off. However, the problem disappeared when I turned 'Enhance Audio' on and then back off.

I spent hours trying to fix my sound, including a full reinstall of Windows. Nothing worked until I came across this thread. I switched off Enhance Audio and it fixed my problem. Thank you!!!!

In my case, my "temporary solution" is to switch Enhance Audio Off and then immediately back On. But that solution is temporary. Very often the issue comes back again and I'm supposed to do the same thing (switch Enhance Audio Off and then immediately back On) (or restarting Windows would also work).
I'm not sure yet what triggers the issue. My assumption now are a few:
- When computer goes to sleep/hybernate

- When I connect bluetooth audio devices and then disconnect (going back to laptop speakers) 

Does anybody know what the trigger for the issue is?

Is the solution for you (Enhanced Audio Off-On) permanent or temporary like for me?

Thanks

The issue I am facing with my 9320 (maybe related) is that everytime Windows Plays its sounds (alerts, notifications...) it "locks" the sound card. Discovered when adjusting volume using taskbar (it plays a Windows Sound when you do so). No other application can use Sound since. That is what I thing is the trigger. Work around: No Windows Sounds.

I experienced the same issue.  This initially worked, now it doesn't, can only hear Windows notifications no videos, music, etc., very aggrevating.

Don't know how you figured this out but it worked for me thank you!

This just fixed my issue:  

1. Logged into my Dell account
2. Select the device with the sound issue.
3. Select Drivers & Downloads tab
4. Click on Check for Updates button within the "Let Dell automatically find driver updates for you.
5. Optional step - walk away, got some coffee, let the dog out...LOL
6. Came back, drivers were updated, perform a Restart
7. Viola, I now have sound!!!!!

This worked for me!  Happened after I connected my USB-C Dock and had external speakers on.  The speakers continued to work but when I unplugged them the speakers would not.  Thank you.
