VirtualBox - No sound after update

Hi. I have described my problem here https://forums.virtualbox.org/viewtopic.php?f=7&t=95560

I think there is a similar problem here https://forums.virtualbox.org/viewtopic.php?f=7&t=93940

In short, there is no sound in guest after update to >= 5.2.32. Has anyone had a similar problem or knows how to get around it?

Another problem is that I can't downgrade because <5.2.32 are no longer supported by gentoo. I don't have sound and I don't have any solution at the moment. :/

Thanks.

I am running vbox 6.0.12. I don't remember which version, but I was having a similar problem at one time. I finally tracked down this ticket: https://www.virtualbox.org/ticket/18342. Issuing this command fixed it:

Cannot believe that it was VirtualBox that was the issue.

Had had no sound in VirtualBox for most of the this year, but had shrugged it off as not essential and I did not have time to look into it. Then I built a new Gentoo host machine, copied across my VM and decided it was time to fix the sound. About a week later and after trying every possible diagnostic tool and setting, including building Alsa from source and tracking the exact instruction where it hung, I gave up. The VM could not be fixed. Installed a new VM from a completely different source and ... same problem.

I wonder why they do not revert the change. I had a look, and to be fair that commit had a lot of other changes in the DrvAudio.cpp file. Sadly no smoking gun or obvious commit message.

Please edit your post title to include [SOLVED] so others can find it quickly.

Brilliant. I never had any need for sound on vbox, and when I tried it today, it wasn't working. This solution helps me, too.

I found this right now - this works for me (after years without sound)
