Hello,
I have discovered a problem when attempting to play music on a Sun Blade
100 through sndiod. The machine will simply panic.
mplayer output:
==========

==========
Running this a second time after reboot resulted in the following:
==========
# mplayer song51.ogg
parse error at line 1
==========
It turned out this was because the config that was generated on the first try
contained garbage:
==========
# cat .mplayer/config
ELF+@#
==========
After removing the config file the system would panic again (this time
generating an empty config which could then be used to crash the system
reliably).
I then tried killing sndiod, and this stopped the system from crashing and I
actually got music on the headset output.
