SoundPusher stream dies every 20-30min

On Catalina (10.15), I use SoundPusher to send a 5.1 optical signal from a USB audio sound card (Sound Blaster X4) to an AV receiver and watch movies using VLC.
However, the stream stops every 20-30min and the right sequence to make it come alive again is (1) quit VLC (2) quit SoundPusher (3) restart sound card. SoundPusher freezes a few seconds whenever interacting with it after the stream has died, until it is restarted.
I would like to troubleshoot this to determine whether this is a SoundPusher issue or a sound card issue, but I am not sure where to look.
Sometimes I have the VLC/system output set to an aggregate device that I set up in the Audio Midi app to have both SoundPusher Audio (=SBX4's SPDIF) and the SBX4's analog speakers active in order to connect surround speakers that are far back directly to the sound card, but the problem happens in both setups.
This is not something that I have seen (and I also use VLC occasionally). I am not using aggregate devices, though.
You may be able to create a "spindump" (e.g. from Activity Monitor) on SoundPusher.app and / or coreaudiod. That might contain an indication of where things are when this occurs.
You can also try creating a sysdiagnose https://apple.stackexchange.com/questions/59917/how-do-you-get-system-diagnostic-files-from-macos immediately when things go back.
Of course, you can also try the Console.app firehose to spot anything in retrospect for the timeframe of the problem.
Thanks. I'll do that at the next opportunity and report back.
@jebediah2 Can this be closed as well?
I think this issue deserves a bit more testing because I think it happens in a particular hardware/software setup. By reproducing it we could isolate the issue and look into whether this is anything SoundPusher can or should address. I'll try and run more tests this week.
