Try to toggle 3D acceleration. See if that changes the situation...

VirtualBox crashes with Skype and Windows 10 guest

Post by happless_user »

Hello,

Sound works fine. Can watch Youtube and use "Sound Recorder".

Joining a conference call with Skype also works, everyone can hear each other.

However, the VirtualBox window invariably disappears after anything from a few seconds up to around 5 minutes.

Tried to set ICH AC97 driver (uninstall multimedia driver in Device Manager, reinstall guest additions, reboot) but could not get Windows 10 to recognize it.

I would expect a BSOD if this was a Windows 10 issue...

Am running Ubuntu 18.04 Host and VirtualBox Version 6.0.10 r132072 (Qt5.9.5).

Zipped log attached.

Let me know what else I can do to help diagnose the issue. It can be reproduced reliably.

Thanks

There's not that much from the log, except:

Are you using a dual-monitor setup and seamless mode for the guest? Can you simplify that if possible? As in 1 main screen in your host and a normal windowed mode (not full-screen, not seamless) for the VM? It may not be audio related.

Yes, so now I tried Windowed mode and only one monitor.

I use Windowed or Fullscreen and never Seamless Mode. However, the log entry reads as if Guest Additions are merely detecting a "capability" for seamless. So I uninstalled Guest Additions to get rid of that log entry.

Here is a run with: no Guest Additions, one monitor only, "Windows 10" vm in Windowed Mode.

Skype still works for a few minutes but also still crashes. Log attached.

As I said your config looks fine, except those two minor screen issues that I mentioned. If it crashes even without those, then you could head to the Bugtracker and file a new report, or reopen an old one. Search for:

3D Accleration is in the main Virtualbox window, click the guest, Display settings, Screen tab, Enable 3D Acceleration checkbox. Guest probably needs to be shut down when doing this. Guest Additions that came as an ISO with the host Virtualbox version should be installed in the guest, too.

I've been just told over IRC that 6.0.10 (and 5.2.32) contained a security fix in the 3D acceleration code, something that affects other aspects as well. It's also my understanding that Skype requires 3D acceleration. So, the solution so far would be to downgrade to 6.0.8 until this gets resolved.

I'll see if there's a ticket for this...

Merged a couple of related threads, moved them to "Windows Guests", added ticket information in the title and first post.

This thread seems to be a mix of "cannot share screen in Skype" and "VirtualBox crashes in Skype". I've recently run into the second issue (crashing). It happened when I changed my USB headset audio configuraton due to the clicking and popping that comes with the emulated USB controller. Hopefully this info will be useful, as it seems to be a clear A/B case.

Host: Linux Mint 19 Tara
Guest: Windows 10 Pro version 1809
Lync: 2013
VirtualBox: 6.0.10 r132072 (Qt5.9.5)
Emulated USB controller: EHCI

Configuration A (Good, except poor USB headset audio quality):
- USB headset (047f:c039 Plantronics, Inc.) populated in the USB device filter section
- USB headset selected in Skype as the audio device
- No special host audio settings

Configuration B (Skype works fine for about 2 minutes, then VirtualBox crashes):
- Nothing in the USB device filter section
- PC speakers and microphone selected in Skype as the audio device
- VirtualBox audio routed to the USB headset in the host, using pavucontrol.


As stated, VirtualBox will crash hard after a couple of minutes when I use configuration B. The log doesn't seem to have anything useful, but attaching it anyway.

Oh-- just for fun I set the Windows power settings to maximum performance to see if it was something to do with putting devices to sleep, but this had no effect.

Thx.

I'm sorry to report that the same thing happens with the 6.0.11 test build. Skype call is fine for a couple of minutes, then a pop and a hard crash of VirtualBox.

Thx.
