Hello,
I have a macmini ppc (g4) that has the following issue with aucat:
When using aucat -l, the music skips quite often, but if I use
mplayer without aucat as server, it works perfectcly. I must say
that the same issue has mpd, that is, using mpd without aucat as
server, has the same skipping problems, although a little less, so
it seems to be the server mode that causes problems. Everything is
fine on my i386 laptop.
I'v tried renicing to -20 as per man page, but without luck. I've
also tried raising memory settings with sysctl, also without luck.
Please tell me what other info you need since I'm no expert.
tks
a dmesg is *always* helpful with hardware issue.
the output of 'audioctl' while you are experiencing problems is probably
useful (there's a faq entry for audio issues, btw).
did you try running aucat with '-m play'?

Using "aucat -m play -l" has the same issue
Here is audioctl while running mplayer with audiocat -l:
