I found it’s way louder in bluetooth rather than usb-c connection, also maybe try update the firmware?

"Hello, I had a similar issue, but I may have solved it on my own. Click on the speaker icon on your taskbar, left-click to open the Volume Mixer, and then click on the sound. Move the slider, and it should work. It worked for me!"

I had the same issue aned the best fix I found was In Synapse, go to Audio > Sound > *Center Focus* and turn it off.

Way louder over Bluetooth than just USB-C.  Night and day difference.

Bump. Still experiencing problems with the speaker as described by topic starter. No firmware updates for the device available, volume in the volume mixer is set to max; there is nothing suspicious in any of the tabs in the audio device properties. Connecting the device to a PC via Bluetooth makes the sound just awesome, but then I lose the ability to control the backlight, and most importantly, the sound will delay about 0.5 s, which is critical for gaming. Looking forward for any tips or help.

Can you describe more detally? What Razer Synapse software version do you use? I cannot see that option on Razer Synapse 4.

I also have the same issue, is this a bug or sth else, now I have to connect it in bluetooth

Its opposite for me, Its real loud when im playing audio off my PC but when i connect it to my apple phone its not near as loud

Same issue and have suspected the my pc case power supply, but BT works just fine so, it’s not more than a bug, FIX IT Razer.

Все очень просто)))Заходим Razer Synapse-Аудио-внизу открыть окно свойств звука Windows-находим свое устройство-свойста-уровни-баланс и выкручиваем в максимум)))Не благодарите

Bro’s right! Somehow the L bar is fixed at, funny enough, 42. Drag it to 100, fixed.
