The current shipped sxmo_record.sh script to record audio files seems to be broken. The quirks and workarounds in this script are not valid anymore. Here is a proposal of a script which records audio as wav, and if ffmpeg is installed also in opus. The input selection is made via sxmo_audio.sh When callaudio finally is fixed, i might add the option to record calls with both parties.

proposals and feedback welcome!
