When parsing volumes out of pacmd, strconv.ParseInt was set to
parse 8-bit numbers. Since volumes can exceed 100% (eg. they can
be values like 140%), volumes can be larger than the maximum value
allowed by an 8-bit signed integer.
This commit fixes that by setting strconv.ParseInt to parse 32-bit
numbers.
