[PATCH 5/5] amixer: use the same characters for separator.

[Takashi Sakamoto <o-takashi@sakamocchi.jp>]

The arguments are parsed as the value of each channel for enumerated
element in sset_enum() and get_enum_item_index(), the former is
a caller and the latter is a callee. Both of them evaluate the string
but use different characters for separator. This brings just cofusion
to users.

This commit fix this bug, by changing callee's characters according to
caller's characters.
