That way, the existing configure options would make it easy to not use ALSA if somebody so desired. I would like to check for ALSA first, before the native check, to fix the problem I am experiencing. A drawback to that approach is that I'll need a new config.h symbol, HAVE_ALSA_SOUND, and I'll have to add "|| defined(HAVE_ALSA_SOUND)" clauses to the existing "defined(HAVE_NATIVE_SOUND)" clauses in sound.c. Does anybody object to this approach? Great. Thanks for the review. I've since figured out how to set the volume, by the way, so I think the actual code is good to go. I just need to get configure right now, and then modify the documentation. Also, ALSA is capable of playing a few more formats than my detector detects (IEC-958, MPEG, GSM). I know how to tell when a file is in one of those formats, but I don't know how to extract the bitrate and the number of tracks/channels in those formats. If anybody in the audience has that information, please let me know. -- Jerry James, Assistant Professor james(a)xemacs.org Computer Science Department http://www.cs.usu.edu/~jerry/ Utah State University
