Ok, thank you for the notice.

I will fix it.

This shouldn't be changed on runtime. It is possible but it does not 
make sense to me.

Firstly we have to stop the device before switching the hybridflow.

Then it changes the available ALSA commands at runtime. The hybridflow 
must be chosen to match requirements of the speaker behind (like 2.1, 
woofer or tweeter).


Thank you for your advices.
