no sound from built-in speakers, but headset works fine

Hi all,

I have been running into a strange problem for a few days:
I don't get any audio from the built-in speakers of my laptop, however my jack/bluetooth headphone works perfectly fine. I am not sure when the problem exactly started because most of the time I'm using my headphone (my fan is noisy)

What I have tried/checked:
- the built-in microphone works fine (on the same card)
- tested both linux and linux-lts kernel. I'm getting the same result
- everything looks fine from gnome: can adjust volume, switch output device, etc. However the sound test won't work on my speakers
- everything looks fine in alsamixer: I can see my card and both output device: Headphone, Speaker. I can control volume/mute. However even though I unmute 'Speaker' and increase the volume I still hear no sound. When I'm doing the same thing with the headphone I get no problem
- similar thing with pavucontrol: I can see music being played in the 'Playback' tab (eg. from Firefox). In the 'Output Devices' tab, whether the card port is set to 'Speakers' or 'Headphones', I can "see" the sound being played back to the device. However I get no sound from my speakers.

Some extra infos (if that can help):

Having same Problem. I will try downgrading pulseaudio and alsa-utils
