improvements from workshop

[capital-G]

Some small improvements derived from the workshop.

The connection problems within the MIT network most likely derive from encapsulating the sound container within a docker network/NAT (see 277c911 ), so lets get rid of this again.

I will try to check out this on the dev server before merging it to verify that it is in a state how it should be.
