Note that parsing a floting point string is tricky. For example, if
you run it in a locale that handles comma as the decimal point, this
gets messy. Did you check it, e.g. with LANG=en_GB or such?

The program name should be a const string.

[Han] may I just change the strings to
" duration overflow ..."
" duration underflow ..."
" duration overflow ..."
" duration underflow ..."
" invalid duration ..."
" duration out of range ..."
Or change the sequence and keep 2 or 3 strings like:
"duration overflow/underflow ..."
"invalid duration ..."
"duration out of range ..."
Since they would be clearer to developer/user?

[Han] OK. I followed the indentation style of aplay, to align with multiple-character options such as "--log=#". Shall I remove indentation for these options?

I would probably just have "duration overflow/underflow" and "invalid
duration". That cuts down 6 strings to only 2. Likewise for other
strings.
Remember to also include variables in the error output that will help
identify the error cause (since we wont be able to determine the exact
error line by string text).

You could even try using a : or similar (instead of commas) to
deliminate the input string. e.g. -values 1.2, 4.5 would become -values
1.2 : 4.5

easier. But in general, please give a good documentation describing
how to use it, at best, in a form of man page.
I'll give some comments in each patch later.
