Description

When the "Autodetect muxes" option is enabled on an adapter, it will also update already known muxes. However, there is something wrong in the mechanism, as this will sometimes mix things up and configures muxes with an wrong configuration (see below). This results in services beiing unavailable.

Also discussed (a bit) in this thread: https://www.lonelycoder.com/redmine/boards/5/topics/7037?r=7450

In this case I could not get a lock on the channel on adapter22 because it changed the configuration with incorrect parameters.
When I adjusted the prio of the adapters, so that adapter21 would be chosen, the channel locks and streaming started.

To verify, I checked the configuration files of the adapters, and they match the output of the log file.
