I regret to inform you that "wavparse" also yields a "no element" error.
I did a bit more looking around and it appears that they have stripped things down to the minimum they need. I checked what gst binaries were present and at least they left gst-inspect, which shows:
Code:
coreindexers: memindex: A index that stores entries in memory
mixersink: mixersink: Audio Sink Mixer
audiblesrc: audiblesrc: Audible source
coreelements: multiqueue: MultiQueue
coreelements: typefind: TypeFind
coreelements: tee: Tee pipe fitting
coreelements: filesink: File Sink
coreelements: queue: Queue
coreelements: identity: Identity
coreelements: filesrc: File Source
coreelements: fdsink: Filedescriptor Sink
coreelements: fdsrc: Filedescriptor Source
coreelements: fakesink: Fake Sink
coreelements: fakesrc: Fake Source
coreelements: capsfilter: CapsFilter
staticelements: bin: Generic bin
staticelements: pipeline: Pipeline object
Total count: 5 plugins, 17 features
So this is all you have to work with using gstreamer. Is this sufficient? If you have mplayer handy, the one here on the pw4 is MPlayer 1.0rc4-4.4.5 (C) 2000-2010 MPlayer Team, then perhaps you could test things as well since you are more familiar with gstreamer.
The full list of gst binaries is:

-rwxr-xr-x 1 root root 17692 Nov 27 2018 /usr/bin/gst-xmlinspect-0.10
As you can see above the pw4 has gstreamer 0.10 as opposed to any other release.
Let me know of anything else I can try for you.
If this is insufficient support I guess we need to investigate libaudioclient instead.
