Comment(by Quozl):

 No, Samuel, the problem is that there are two channel controls, but they
 are linked to the same underlying control.  In the #12550 commands, the
 underlying control is set twice, and the last setting is what is visible
 on viewing.

 "amixer set Master 20" becomes
 {{{
 x = 20;
 x = 20;
 }}}
 "amixer set Master 20,0" becomes
 {{{
 x = 20;
 x = 0;
 }}}
 "amixer set Master 0,20" becomes
 {{{
 x = 0;
 x = 20;
 }}}
 And in #12527, "amixer set Master 10%+" becomes
 {{{
 x += (x * 0.10);
 x += (x * 0.10);
 }}}
