Disclaimer: I have little idea about the inner workings of osspd. I just
have it working fine here on my machine with PA 7.0. The test suite
never worked for me, either.
I am testing it like this:

> gst-launch-1.0 filesrc location=./filename.ogg ! oggdemux ! vorbisdec ! audioconvert ! audioresample ! osssink

So, in principle, osspd *is* compatible with PA 7.0. My first guess for
your problem would be that something is wrong with the permissions
somewhere. Do you have udev set up to set the permissions of /dev/dsp
etc. correctly?

Is there anything special, non-default about your PA setup? Like, I
don't know, using a system daemon or any other changes you made in
/etc/pulse or ~/.pulse ?

Kind regards,
Ralf
