Techwin SNH-V6414BN audio drops off

[protonpopsicle]

With Techwin SNH-V6414BN camera, STAVPlay plays back the audio on the TV for awhile (sometimes seconds, sometimes minutes), then suddenly there is no sound, though the audio level indicator continues to display DB values as before. I did not see any errors in log messages. Sometimes making a loud sound near the camera (such as tapping the camera, or scooting it around on a surface) seems to hasten the problem.

I have not tested with all other cameras, but the issue is definitely not present with Arlo.
