Glitch-free for *everyone*, except those for whom PA refuses to talk to
ALSA (*waves*) or refuses to use the high-def timers that definitely exist
(*waves*).
I really must diagnose this, but trying to find bugs in ALSA's kernel
component is like trying to shovel sewage with a toothbrush. Its
kernel/user interfaces are horrible (and most of both components is
entirely undocumented as far as I can tell: I still have no clue what the
Lisp interpreter is doing in there, for instance. Maybe the docs are just
hiding. Maybe they appeared since the last time I looked at this a couple
of months ago. But, y'know, life's too short: PA mostly works for me now,
and hardly ever glitches even with glitch-free mostly turned off by the
enforced usage of the OSS compatibility layer.)
