No sound from any guest OS (#17076)
No sound from any guest OS (#17076)
[ModEdit, related ticket #17076: No sound from any guest OS]
Hi,
I have VB5.1.26 on a Windows 8.1 Host. I use Ubuntu 10.? and Ubuntu 16.04.03 LTS and Windows 7 guests. I don't hear any sounds from any of the guests.
Sounds work fine on the Host OS.
I have configured the guests to Enable Audio and use Windows DirectSound with Intel HD Audio. I have also tried AC97. This problem has existed for me for a long time, also with older versions of VB. I have looked at the Manual, FAQs and web guides, but they don't help.

Re: No sound from any guest OS
Pick a VM, let's say Win7. Follow a "start the VM from cold-boot" / "observe error" / "shutdown the VM" cycle. With the VM shut down completely (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log". Save only the first "VBox.log", ZIP it and attach it to your response (see the "Upload attachment" tab below the reply form).

Re: No sound from any guest OS
Here are the relevant parts of your VBox.log, with the last line I believe to be the most important (which I wrapped for readability). I, unfortunately, have no clue what it means, what causes it, or what might fix it. Let's hope someone else does:
Other than that, you may want to lower the number of vCPUs that you've assigned to your guest. You have 2 physical CPUs and you've assigned them both to your guest.

Re: No sound from any guest OS
Could this be down to Windows' Exclusive Mode?
(BTW: I have 4 cores in the CPU).

Re: No sound from any guest OS
I don't know what Windows' Exclusive Mode is, but from a quick read, that might be it.
BTW, you have 2 physical cores. That's all VirtualBox cares about, not marketing booya...

It's an AMD A10-7850K CPU.

Re: No sound from any guest OS
<sarcasm>
Oh, I'm sorry, I didn't realize...
You actually have 128 CPUs, but due to marketing, they only reveal 4.
You have to drink the magic potion to see the rest....

Re: No sound from any guest OS
I really wish they wouldn't nobble CPUs like this.
FWIW I have disabled Audio exclusive mode but I still don't get sound in the Guest OSs.

Re: No sound from any guest OS
Anyone have any ideas how I can progress this issue?
Re: No sound from any guest OS
Thanks for the post, but I don't think it helps. I have tried Intel HD Audio as well as AC97 with the same results (i.e. no sound).

Re: No sound from any guest OS (#17076)
It's not like it's fixable if you change a setting. There are fundamental problems with the audio, something that they're actively working on. Your best bet is to install the latest test builds and hope for the best. Patience my young padawan...
