FYI, according to the OpenSolaris source, SPARC machines
with AC97-based on-board audio use the AC97 MONO_OUT for
the internal speaker, which in FreeBSD is mapped to
PhoneOut. Turning the latter on in the Blade 1500 indeed
gets its internal speaker going with a decent quality.
This also means that in the GENIALstation 777s the
"stereo" jack is wired to a mono output, which probably
explains the lousy sound quality.
