I have been trying to troubleshoot this for a couple months now with no success. This week I realized that the same pipeline does work on my Mac, just no on the Raspberry Pi. Here's some details:

This smells like a clock sync issue. Have you tried pulsesink
provide-clock=false already?

How are you feeding data into the appsrc? It would be best if you
could share a minimal test case for this. Also try feeding raw audio
data into appsrc instead of opus.

Does this pipeline work on the rpi?

audiotestsrc is-live=true ! opusenc ! queue ! opusdec ! audioconvert !
audioresample ! queue ! pulsesink
