if arts is capable to use alsa then the only thing you need to do is to start
the artsd with the '-a alsa' switch, since artsd uses oss by default. The
problem here is that for every current user this must be changed... KDE/artsd
does not do an 'autodetect' and will only give a warning that /dev/dsp could
not be opened.
it is probably easier to compile tha ALSA OSS simulation into the kernel so
things will just work as they used to.
or use this patch and ebuild to recompile alsa. This will put alsa infavor of
oss on autodetection. put ths patch in /usr/portage/kde-base/arts/files and
the ebuild in /usr/portage/kde-base/arts (overwriting the existing one)
