The title says it all. I bought a clevo laptop and the builtin speaker is not working.
I tried every possible solutions here : No sound from speakers, but headphones work but non of them worked.
The sound works on my USB Headset, and on my monitor, but not on the builtin speaker. I think it may be a problem with alsa because pavucontrol shows that there is sound but I can't hear it.
The built in speaker was working when I turned on the laptop for the first time with windows preinstalled on it.
I don't really know how the linux sound system works. Please let me know if you need more information to help me (log files, etc)
