[S451LA, Realtek ALC3236, Speaker, Internal] No sound at all

[Guilherme Alberto de Moraes]

Yesterday my notebook was working like a charm, but today it does not make any sound, and does not hear anything also. I have checked the sound tab at system settings, and the output device bar was working when I played music, altough I could not hear anything at all. Also, the input device bar did not move when I did speak.

I do belive this bug is somehow related to the headphone. Yesterday before shutting down the PC, I was listening to music with a headphone pluged at the 3.5mm jack, but today before powering it up, i took it off. Also, when I change the volume, the popup display showing the volume level is labled with "Headphones".

Oh, and of course, I tried to restart the PC, it did not work.
