[FFmpeg-user] Catching all error warnings via ffprobe

Hi - I've done some more tests and either I'm missing something here or
perhaps this is a bug? It seems like only video errors appear in the JSON,
not audio.
I bumped up the loglevel, added and -show_error and I'm still not seeing
the mp2 header issues appear in the json.
For example this appears in the terminal:

[mpegts @ 0000023d706538c0] Continuity check failed for pid 2069 expected 7
got 0
[mpegts @ 0000023d706538c0] Continuity check failed for pid 2068 expected
10 got 9
[mpegts @ 0000023d706538c0] PES packet size mismatch
[mpegts @ 0000023d706538c0] Packet corrupt (stream = 1, dts = 203200560).
[mp2 @ 0000023d70767e40] Header missing

but I see no errors in the audio frames section of the JSON output:
{
            "media_type": "audio",
            "stream_index": 1,
            "key_frame": 1,
            "pkt_pts": 203200560,
            "pkt_pts_time": "0:37:37.784000",
            "pkt_dts": 203200560,
            "pkt_dts_time": "0:37:37.784000",
            "best_effort_timestamp": 203200560,
            "best_effort_timestamp_time": "0:37:37.784000",
            "pkt_duration": 2160,
            "pkt_duration_time": "0:00:00.024000",
            "pkt_pos": "7371266244",
            "pkt_size": "1152",
            "sample_fmt": "s16p",
            "nb_samples": 1152,
            "channels": 2,
            "channel_layout": "stereo"
        },

It seems that any errors for the audio streams are not making their way
into the JSON, but the video errors are, as per my last email.
Any guidance on how I can get these audio errors into the JSON  - am I
missing a command or is this a bug?
