I do have it installed.  I also tried to install `libavcodec-extra` at
some point (when I saw that `mp4a-latm` 🙂), but it made no difference
of course.

Thanks.  When I "disable sandboxing" (by setting the three vars
I mentioned in my answer to Tomas) it says:

    Audio Backend:		alsa
    Max Channels:		0
    Preferred Sample Rate:	44100
    Roundtrip latency (standard deviation):	...
    Codec Support Information:
    	VP8 SW
    	VP9 SW
    	AV1 SW
    	Theora SW
    	FLAC SW
    	MP3 SW
    	Opus SW
    	Vorbis SW
    	Wave SW

with no input nor output devices.

So it looks like the codecs are found in that case, but the audio
backend is wrong (it should be Pulse, AFAIK) and the max channels shows
that there's really no output.

If I leave the sandboxing options at their default setting, then I get
a similar result except that the list of codecs is empty.
