You should be able to, but pulseaudio no longer supports oss. See the 'oss' USE flag in: https://wiki.gentoo.org/wiki/PulseAudio Pulseaudio upstream no longer supports oss.

When in brackets like that it means it's forced in that position and you can't change it. In this case, it's because upstream deprecated oss support in pulseaudio.

You can't, as far as I know. In this case the flag seems to be removed (equery uses pulseaudio doesn't list oss as a valid USE-flag) and it might be a bug in the package as you shouldn't be able to set oss any more.

You might still be able to use oss but you won't be able to use pulseaudio with it. If you remove pulseaudio as a dependency (and not install it) it could work? (I'm sure if I'm wrong someone will point it out...) Dan
