Hi-

   Just did my roughly-annual (B)LFS reinstall and Firefox (compiled
   with ALSA) won't play sound. ALSA itself is working, since mpg123
   plays fine. But, when I attempt to play a video with sound in
   Firefox, I get errors like:

ALSA lib pcm.c:8865:(snd_pcm_set_params) [error.pcm] Sample format not
available for PLAYBACK: Invalid argument

   This seems to be saying that there's an audio codec missing; but not
   sure I should believe that. And, if I should, any way to track down
   what it is?

                -Andrew Warshall
