Playing a sound file with mpg123 would be an acceptable alternative,
which I do when building BLFS. But how when I'm building LFS? I've
tried linking host programs with no success.
aplay?
if [ $? -eq 0 ]
then
aplay "happytune.au"
else
aplay "braaak.au"

Yes, but how do I do that when logged in as LFS. I receive:
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:4259:(_snd_config_evaluate) function snd_func_card_driver
returned error: No such file or directory

ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM default

If I can fix that problem with aplay it seems I could use the same logic and
use mpg123.
