I workd on 6f9835f. After testing, rebase to current master. Then I 
missed 1a19ec1. I should have compile again in this tree. (missing 
enough caution...)

Well, I think the 1a19ec1 still includes a bug. It cannot parse this 
option correctly.

$ amixer sset enum-element-13,1019 A,B,,D

In this case, no values should be set to the third channel of the 
element. But current implementation set D to the channel and the last 
channel is not changed.

I'll post a new patch, later.


Thanks for your indication.
