1. Open the application called ‘Terminal’
2. In this application run the command:

sudo eos-rollback

[egrath]

As an alternative to rolling back to the previous version, we can also try to find the root cause of the issue.

Open a Terminal and type:

aplay -l

this will output the devices found by the ALSA Soundsystem (the lowest level of Audio Subsystem in Linux). It should display something like:

Please provide us with your output. Your issue is, that Audio Sink (=the device where to play audio) does not get registered with PulseAudio (Soundserver), so we have to manually add it to the configuration.
