Odd sound at start of VM.

Postby isgdre » 6. Sep 2017, 18:49

When I start a VM I get a lot of crackling, sputtering from the sound card. It seems to last for about 10-20 seconds and then is fine after that (for each VM independently). It's consistent. This is new to the Bata 2 (didn't try bata 1). But didn't happen in V5.1.22 or before.

The guests are Windows 10 pro, Windows 7 Pro, Ultimate, and Pro N.
The Host machine has a Asus xonar dsx audio device and here is the systeminfo on it.

Can you please supply the VBox.log when reproduced the issue? Without the log there's not much we can do ... Thanks.

Also, can you please provide a dump of the crash you were experiencing? See https://www.virtualbox.org/wiki/Core_dump about how to do this.

Looking at the core dump link, it assumes you still have access to the Host computer. I did not, the whole thing hung.
Would there be anything useful in the VLog? *IF* the cpu halted then it will not get a chance to log anything. Is there a verbose mode for the vlog that would help?

Hm ...if the host really hung that hard that this must be something more serious. So the host entirely has frozen and did not recover without doing a restart, right?

Does this also happen if you disable audio completely?

Had to hold the power button for 5 seconds to get it to power off.
I could try pulling one of the power cable and see if it beeps. If that would help diagnose just how dead it is. I'm not sure if that's just hardware doing that but I think the beep is coming from the mother board speaker.

By completely disabling sound I'm going to assume you mean just remove it from the VM definition and not removing sound card from the host. I'm ok to do this as a test but it's not a solution as the sound is required in the VM guests.

Ok, just wanted to be sure, thanks.

Regarding disabling sound: Yes right, completely disabling audio via the VM settings. This would help pinpointing the issue further.

So, Things broke going from V5.1.22 -> V5.1.24. Still didn't work in V5.1.26. Tried Beta 2 and got different problems. First sound then crashing. Now V5.1.28 seems stable again. I'm thinking it was the sound changes that caused my grief and it looks like you also included that change in Beta 3. I'll try in a bit but have to get caught back up again.
