It's ok, it's just a wrong use of the alsaucm command. The PA should activate 
HiFi verb only once. Those two commands run the verb EnableSequence twice.

The correct test should be:

alsaucm -i -c bytcht-es8316 set _verb HiFi
alsaucm>> set _enadev Speaker
alsaucm>> set _enadev Headphone
alsaucm>> set _enadev Mic
alsaucm>> set _enadev Headset

... you may run the enable commands with a delay for tests.

The current UCM is designed for one task (application). I am playing with an 
idea to extend the alsactl state daemon to preserve the UCM settings and state 
for multiple applications using an RPC mechanism (dbus?).
