no sound after upgrading to ubuntu 18.10 from 18.04

[Thomas Schweikle]

Ubuntu 18.10 does not recognize sound devices. After upgrading there is only a dummy device known. All others are gone. In tune there is no sound output to nowhere.

It does not mater it headphones are plugged or not while booting. It does not matter if any usb-sound device is plugged or not. The only device show for output in mixer is "Dummy device".

I have this problem too, how can I fix it? I have Acer Aspire V Nitro II.

[Libor Šedivý (liborse)]

I found solution with command: "sudo apt purge timidity-daemon", and then reboot. After this, sound works like sharm.

[Thomas Schweikle (tps)]

Yes, that is it!

systemctl stop timidity.service
systemctl disable timidity.service

solves the problem.

Status changed to 'Confirmed' because the bug affects multiple users.
