I have this exact issue on a new Dell Latitude 9430 laptop with Windows 11.  Really frustrating.

My 9430 is also having this problem. Audio will cut out and not work again until I restart (except for volume up/down sounds). Already tried BIOS updates, reinstalling OS and updating audio drivers, but the issue is still there.

I must add that this happening on my 9430 2 in 1 as well, fixes seem pretty random, sometimes waiting does the job, sometimes even restarting the device doesn't change a thing. It would be great if Dell addressed this issue.

Me too; totally frustrating. Bought my 9430 2-in-1 two months ago, and while loving it for almost everything, this issue is driving me nuts, and wasted many hours trying to resolve it without luck.

In the beginning, it was the issue described in the original post: worked after a clean start for a few hours or until sleep/hibernation. After a recent BIOS update (1.9.1) and/or another attempt to solve it, now the audio is usually reporting disabled by default for YouTube, Spotify, and other apps (though the default Windows sounds are still present), and disabling/re-enabling the audio device helps only. What's even worse: now the Audio panel from Dell Optimizer is gone, due to which I'm unable to control noise canceling anymore, which is quite annoying for my conf calls.

Tried disabling/removing everything Dell-related + disabling and re-enabling devices on BIOS/Windows level, and then reinstalling all Dell drivers, but nothing really helped.

I thought to write to Dell, but seeing that this nonsense has been going on for years with completely different models, I don't have high hopes. Although it's pretty disturbing that a high-priced business laptop has such flaws, and most certainly not due to hardware but software/driver issues.

Since I upgraded to Win 11 from the beginning, is there anyone maybe using Win 10 still and eventually not suffering from these issues there?

HI buddy

I have issue with all streaming.the only solution is going to sound setting,then mono audio make off and then on,refresh your streaming page and will work,i did on windows 11 and is working

but didn't find any solution.

cheers

Also having the same issue. £2500+ laptop cant even play youtube videos. Will someone from Dell be able to respond to this thread?

Actually, I think I achieved a breakthrough finally (though I don't want to celebrate too early): I found a tool called Driver Talent (https://www.drivethelife.com/) (and no, not associated with them by any means, I just found it in a forum talking about similar issues). It has the option to show the list of outdated drivers and update those. Many of my Dell/Realtek drivers were showing up outdated (although I installed all the latest ones from the Dell Support site, neither Windows update or Dell Command | Update was showing any updates). It was also interesting that "Realtek SoundWire HW Audio Codec Driver" entry was present several times, with slightly different versions -just a wild guess, but looked like it was installed more times or different sub-devices used different outdated versions.

Long story short, after upgrading every one of these items, the issue seems to be gone, I finally have a properly working sound card, and I can play videos, Tidal/Spotify whenever I want, even after putting my laptop to sleep and coming back hours or a day later.

What still didn't fix that the Audio panel is still not present in Dell Optimizer since either the latest BIOS update (1.9.1) or due to all those driver uninstall-reinstalls, and I can't control the noise canceling for the microphone, which is a pain. Soon I'll reinstall my laptop due to this.

I hope, though, that this utility can help you guys.

We just bought a couple of 9430's to test and I'm seeing this issue on both of them.  The drivers Dell has released for this system are not good...at all.  They need to fix this. 

My observations so far: 

1) You have to have audio enhancements turned on for system audio/streaming web video audio to work.  Period.  If you disable it, you will lose all sounds not playing through a media application.

2) Media applications like Netflix or Hulu work with audio enhancements on or off.

3) After a few hours, system audio and all streaming web audio will crash.  You need to disable and then enable audio enhancements to get it working again.

Dell, I cannot stress how frustrating this is for many of us.  Please fix your drivers.

As a reminder, I'm still happy with the solution I described above; since then, the audio has worked perfectly, no matter how long I use the laptop/put it to sleep/hibernate in the meantime, it just works.

My only issue remaining is that since the BIOS update, the Audio panel is still gone from Dell Optimizer and I can't turn on the noise canceling for my calls. But I think it's unrelated to the current driver issue/update.

Due to missing noise canceling options I reinstalled my Windows from scratch. Long story short, right from the beginning on a very clean install I was having issues with sound coming from video/streaming/tidal sources again.

Again I could fix it with Driver Talent Pro software, after it has updated all drivers, it just got fine - and since I didn't reinstall Dell Optimizer, I still have the Audio panel there as well and working noise canceling.

What is wrong here, I have no idea. In this software, it seems that several instances or devices having this same awful driver need to be updated, and for some reason, Dell Updater doesn't do it. 

I don't even care anymore; I lost dozens of hours trying to resolve this. Happy this piece of software helped. For security, I made a system image from the current state of the system, if it ever gets  again to go back.
