Are you sure that's good enough?  It does not list the PCMs in a format
useful to the application (like "default", hw:0", "surround51", "dmix"
etc).  AFAICT "aplay -l" doesn't give an application enough information
to populate a drop-down list.

This is a problem already for apps like "wengophone" - ALSA does not
provide a sane API for enumerating all usable PCMs so it only lists
"hw:x" PCMS and whatever is directly defined in .asoundrc (but NOT the
PCMs defined under /usr/share/alsa/* - probably it parses .asoundrc
directly, ugh)
