PKGBUILD of pam adds the relevant lines to limits.conf:

As such, pulseaudio is presumably unable to function in the way intended by upstream.

Oh, I fail at reporting bugs in the right category. I'm sorry.

pulseaudio uses rtkit, it does not depend on the audio group.

This would only have influence if you're member of the audio group. Consider this: you don't need to be member of the audio group, only if you want to use the "realtime scheduling" that it allows you to do (big DoS hole imho). If you want realtime scheduling and direct access to the audio device, why would you use pulseaudio then?

Is this still an issue?

A PulseAudio user should not be in the audio group, as PA depends on losing access to the audio device when the active session switches in order to hand over the device to the newly active session. PulseAudio asks rtkit to alter its scheduling parameters.
