[Inspiron 13-7359, Conexant CX20722, Speaker, Internal] No sound at all

[Manikanta Bhagavatula]

I am not able to listen to the sound on bootup and when I login I cannot hear any sound on browser, not even the bubble pop sound that we typically hear when the volume increase button is pressed. Kindly fix this at the earliest. Thank you.
