The best way to do that is with the gstreamer-properties application.    Using that you can select OSS audio output and the specific device to use.  That should solve the problem for you.

I updated to 151 today and sunaudiosink is now at least producing sound.
Gnome's Multimedia Selector is also now updating gconf settings. But
it's still the same, horrid, scratchy, distorted sound that I get using
OSSv4.

The thing in common here seems to be that we're both using nVidia
onboard devices.  Mine, at least, worked perfectly with prior
Open/Solaris.  And since Sun based one of their amd workstation
offerings off this same Tyan K8E (S2865) mainboard, one would think that
any changes to the audio subsystem would include support for these
drivers.
