Volume getter and setter behave inconsistently about mopidy-alsamixer HOT 3 OPEN

Sounds similar to #19

from mopidy-alsamixer.

The issue gets worse when using smaller volume steps as then volume changes are ignored (see #19). The fix for me is using the volume scale 'linear'.

Just a hunch, but perhaps there is something wrong with the assumptions of transforming volume into mixer values and vice versa? The readme of the alsamixer-plugin states that 'cubic' matches the volume scale used by the alsamixer software. Yet if I use linear, getting and setting volume work consistently – and every change is reflected by the alsamixer command line util. So if alsamixer software uses cubic and by using 'linear' in the plugin I can control alsamixer, why the additional transformation of volume values in mixer.py? Anyways, since the error I observe may very likely be the cause of #19, too, perhaps it makes sense to make 'linear' the default setting, at least for the time being.

I just want to add that incrementing and decrementing also makes for the same inconsistencies. For instance increasing the volume by 5% occasionally leads to a 4% increase.
