Sound is crackling

Post by Leloup78 »

Bonjour,

When watching video, at starting, sound is correct for 10s then the crackling increases dramatically. To fix this issue, I stop the video. I wait one or two seconds. I read again video. Sound is correct for 10s then this noise increases again and so on.
if I don't do something, the issue dispears then occurs again.

Do you have any idea where does that come from?

VM 5.2.18 r12319
Guest: Linux Mint 19 Xfce
Host: Win7

Regards,

Le Loup

Have you searched the forums? For sound problems? You wouldn't be asking that question if you had... ;)

Sound is an issue, especially with videos. They're working on it for a long time now, because it's a really difficult problem. The one biggest "issue" in a virtual machine is timing. And A/V really depends on accurate timing...

Try the latest 5.2.x test builds and/or development builds. There are almost daily improvements, but remember that things might actually get worse, there's that possibility, especially with the development builds. Read the whole page carefully!

The VirtualBox competitors made proposal to add a virtual sound adapter to the virtual machine. By default, the virtual sound adapter is not installed in the virtual machine. Have you wind that the VirtualBox designers have proposed the same thing or something equivalent?

I'm not even sure what that means. Almost every VM template comes with a sound card that is appropriate for the guest that you're installing. What exactly are you talking about? What's *not* installed?

I know of a couple of developers that are going to have a big smile now... ;)
