David; I already have libasound2 v1.0.13-2 installed on my machine (although

I don't know if it's really installed correctly and working). Do I need to install the 'dev' version of the library to use the ALSA version of Chuck?

Yes. libasound2 is what your system uses to play sounds over ALSA. libasound2-dev is what you use to compile programs that will make use of these ALSA drivers. These are like two interlocking pieces of a puzzle, not like two alternatives.

Or is the version I have too old?

I would expect it to still work, as long as the versions of library and the -dev versions line up. I'd simply try and see whether you get complaints. Hope that helps, Kas.
