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:

Code:
-rwxr-xr-x    1 root     root          9244 Nov 27  2018 /usr/bin/gst-feedback
-rwxr-xr-x    1 root     root          3173 Nov 27  2018 /usr/bin/gst-feedback-0.10
-rwxr-xr-x    1 root     root          9240 Nov 27  2018 /usr/bin/gst-inspect
-rwxr-xr-x    1 root     root         30308 Nov 27  2018 /usr/bin/gst-inspect-0.10
-rwxr-xr-x    1 root     root          9240 Nov 27  2018 /usr/bin/gst-launch
-rwxr-xr-x    1 root     root         20276 Nov 27  2018 /usr/bin/gst-launch-0.10
-rwxr-xr-x    1 root     root          9244 Nov 27  2018 /usr/bin/gst-typefind
-rwxr-xr-x    1 root     root          9624 Nov 27  2018 /usr/bin/gst-typefind-0.10
-rwxr-xr-x    1 root     root          1734 Nov 27  2018 /usr/bin/gst-visualise-0.10
-rwxr-xr-x    1 root     root          9244 Nov 27  2018 /usr/bin/gst-xmlinspect
-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.
