Alsa mixer can't find control due to trailing space

[chourmovs]

Hi !

I can reproduce the bug from here
https://discourse.mopidy.com/t/alsa-mixer-can-find-control-due-to-trailing-space/4195
I don't know why it has not been posted here instead, nevermind

I can't set my DAC as control mixer: both 'NuPrime DAC-10' and 'NuPrime DAC-10 ' with a trailing space as control in alsamixer section leads to mopidy output error, then close

Maybe more a mopidy rather than a plugin issue, tell me i will try to help if posting elsewhere is needed

Thx for your work
