Architecture: sparc64

>Description:

After booting the first audio playback "stutters" on my U2. If I stop
the playback and start it again, everything is fine. This might be
driver related:

audiocs0 at sbus0 slot 13 offset 0xc000000 vector 24 ipl 8: CS4231A
audio0 at audiocs0: full duplex

but I can't reproduce the problem a sparc Krups, which uses the same
audio chipset. This started happening after the recent soft interrupt
changes + pmf merge, but it still happens with all pmf_* calls 
commented out in sys/dev/audio.c.

>How-To-Repeat:
Reboot, run "mpg123 *.mp3", notice repeated samples and ugly sound
output, ^C it, try again: notice it works fine now.

>Fix:
n/a

 Note, however, that your last change did improve audio playback a lot - starting
 up firefox does not disturb audio any more.

 On sparc (Krups, pretty fast v8 cpu) with the same audio chip on pci,
 audio playback is mostly unusable, probably due to latency.
