Zoom may be crashing RealTek Audio Process AUDIODG.EXE

We see a crash from Skype on one device in the Event Logs referencing 'DllHost.exe' and the  C:\WINDOWS\System32\combase.dll file. The 'Zoom.exe' crash references this same file as well on the device in the event logs.

We are experiencing the same issue with Dell aio Optiplex 5270s.

Once you select to Join with computer audio, zoom crashes along with the windows audio service stops.

The issue seems to have started with the Realtek Audio driver 6.0.8940.1 - If you are able to downgrade the driver to the previous version, it seems to fix it but that is a manual process which is not viable for the 200 workstations across multiple sites that I am experiencing this issue with.

Have you had any joy with this issue?

I've tried 3x Dell Drivers and 2x WHQL drivers by removing all Realtek software and letting Windows take over managing the device. I was able to confirm it continued to happen on these versions. Users are on the latest Zoom using auto-update. The trouble seems to be it's hard to reproduce so we never know if it's fixed. You'll think that a new driver does the trick until it triggers again. Keep an eye out for users reporting the issue on that downgraded driver. I recommend opening a case with Dell so they can escalate to the Advanced Resolution team. You'll be asked to fill out an MDS (Multiple Systems Down) forms to provide details on the machines.

My next thought is that rolling back Zoom from 5.1.x to 5.0.x might help but I can't risk using any more users as canaries. We're going to swap out some of these new laptops with competitors' devices as we can see this is going to be a long crawl through support territory with Dell.

Thank you so much for your detailed troubleshooting and making this issue known.

We've had inexplicable issues with our Dell Latitude 7400 laptops and the folks who heavily use Zoom (execs). This exact same thing is happening and we've been at our wits end. We've tried literally everything. I have tickets in with Dell, Zoom, our MSP, and I just don't know what to do anymore!

@fixfinder you're right about it being hard to reproduce! I was able to fix it by simply disabling and enabling the realtek microphone array for one person, and the other person's mic actually worked when the mic was DISABLED! No idea why. These are probably very unstable, nonpermanent fixes, so also ordered external mics for those users. The other person's doesn't work no matter what I do!

I have a ticket in with Zoom that just got escalated to their engineering team so will report back there.

The problem is that once the issue occurs, the mic won't work for other programs either. How frustrating!

@kniemann, indeed! I've got users who have the onboard Realtek array go completely dead. Nothing comes through the microphone in the 'Sound Settings' until I reinstall the driver, or delete the audio device from compmgmt.msc. The folks with headsets seem to have the microphone go dead at the same as the onboard. I've been messing around with removing everything but the Realtek Audio driver like USB/Components and other tools associated w/ Realtek. I've got a machine right now E5490 on 6.0.8895.1, A23 that's having the problem repeatedly. This is the version that support.dell.com is offering as the latest for this model. It's odd because I have a ton of other people on these combinations of drivers/laptops. At this point, I'm convinced it's intermittent across many versions. The hard part is that all of the testing is happening with real people who need to get work done on these calls.

We've sent in an escalation w/ Zoom + Dell Advanced Resolution. Trapping these AUDIODG.EXE crashes with the RMM tools to proactively identify users with issues. The next best thing might be trying to capture the event with Procmon in an effort to further help the vendors isolate where this interaction is happening.

I have the same issue on the OptiPlex 5270.  My workaround is to switch to the Realtek driver or "High Definition Audio Device" made by Microsoft:

devcon update c:\windows\inf\hdaudio.inf "HDAUDIO\FUNC_01&VEN_10EC&DEV_0256&SUBSYS_10280936"

Strangely, the OptiPlex 5250 with the same driver doesn't have this issue.

Might be related....I have the XPS 13 7390, and the Realtek drivers don't work with Zoom. Dell support had me do this workaround, which seems to work:   go to Device Manager -- System Devices, -- find the Intel entry that references audio SST -- update driver -- select browse computer for driver -- select high definition. After restarting, it works much better. Ironically, the Dell SupportAssist on the laptop wants to change it back to the Realtek driver!

Same thing started happing to me, today it happedn tree times in one metting. It seems to happen only when im sharing my screen. HP Pavilion (lol this is the only place i found same issue)
am trying the fix the last commenter posted. Ill update if i have no issues

Hi, I have a similar problem, every time I start a Zoom meeting or Webinar, I have to reset all my sound devices, otherwise no one on the Zoom webinar or meeting can hear me. Resetting the sound devices does fix it, but it's a nuisance as I have numerous Zoom meetings each week.

Buen día, se ha presentado el mismo problemas con varios equipos dell 3468, 3480 y con equipos de otros fabricantes, al parecer es tema de zoom, de momento es solo reinstalar el driver para corregirlo es fastidioso para  el numero de usuarios que se manejan y hay que hacerlo dos o tres veces cada 5 días.

Wow I thought it was only me! Last week, 30 mins a Zoom call, Zoom suddenly froze and hanged... Only after a full system restart, the issue was fixed. I ignored it back then.

But this week same issue happened but with Webex! 

After the crash, I can play videos in VLC player, but Youtube videos do not play.
