BTA30 Pro TX mode audio drops off when source volume levels are low, for example during talking scenes. When the audio rises above a certain level, sound output resumes until the scene gets quiet again. Very similar to https://forum.fiio.com/note/showNoteContent.do?id=202112272301078338704&tid=4

I only have headphones that use SBC and I only have USB audio sources. This problem occurs in UAC1 mode and UAC2 mode on my Windows 10 PC, and it occurs on my PS5. It happens on my Bose Noise Cancelling Headphones 700 and on my Jaybird Vista set. It happens with both Adjustable and Fixed volume control modes. I'm using BTA30 Pro firmware version 1.3.

Please help me.
