No Sound on any site

I am not able to hear any sound from brave browser.
Neither on speaker nor on headphones.

I have also disabled the hardware accelaration and tried creating a new profile. But none of them worked. I can hear the sound from my other browser (qutebrowser).

Os- Linux (Arch)
Brave Version: 1.26.74

And also I am not using any DE but a standalone WM (xmonad) so I cannot access the sound controls.
