I’m having problems with sound to and from snap apps.

If I install WSL Ubuntu 22.04 from Microsoft Store the sound to/from snaps works right (apps tested are Firefox and my own guitarfinetune). Also if I upgrade the distribution to Ubuntu 23.10 the sound to/from snap apps keeps working.

but if I install sudo apt install -y update-manager no sound gets through to/from snap apps. In apps not installed as snap the sound works fine.

It seems to be if wireplumber is installed that the sound to/from snap apps is broken!

How do I repair the sound system to/from snap apps?

Did you mean that the sound stops working after you install update-manger and do a distro upgrade? Is update pipewire/wireplumber running after the upgrade?

make sure that your all the system package including snap and wireplumber are up to date. for this run command to get this: sudo apt update

Yes the sound to/from snap apps stops working after installing wireplumber which is installed when update-manager is installed.

How do I check if pipewire/wireplumber is running ? (Since the sound to/from non-snap apps works I guess they are running).

I did do an up-date/-grade
