While I admit that the audio volume for records is lower than MP3s via Bluetooth player, I also noticed an anomaly that you might be experiencing. You see, I accidentally knocked the stylus cartridge (aka the needle) off of the arm of the record player, and it was no longer connected to the device 100% of the way. Without a complete connection, you can still hear the audio coming from the record player, but it sounds incredibly quiet. It’s so quiet that you can barely because it sounds like a whisper. My suggestion to you is to check the stylus cartridge and make sure it is completely connected. In fact, take the cartridge off and put it back on again following the instructions in the instruction manual to the letter. This should solve your low-volume audio problems when listening to records. It worked for me and it should work for you too.
