How do I increase the low time warning volume?

I'd like to increase the low time warning volume, so that it ACTUALLY warns me that the game is about to end on bullet chess. Does anyone know how to do this? Bullet chess is the one of the craziest fun games to play, but the low time warning doesn't work for me. As it is, the weak sound rarely registers because of the adrenaline hyper-focus mode I enter into. 

Thanks M

same here. i don't ear any sound/beep. any other setting we have to enabled? i agree in bullet game, the alarm is a must...

I just created a free chrome extension for low time alerts.

It has:

- Custom low time notifications with a few different sounds

- Optional 5 second countdown

- Optional screen flash if you're hard of hearing
