My problem is that I recently bought a laptop and it is not a super computer so the performance was bad with Windows 11 (Default OS) then I decided to change to Ubuntu 22.04 (I already have it in my Desktop PC with no problems). Once intalled Ubuntu I realize that there is no sound, I saw the config and the output says "Dummy output" and there is not any other option to select.So i tried with a lot of things and I have some info that maybe unorganized as I have it will not work for me but maybe some one can help me. Thanks.
Info:
lspci | grep -i audio00:0e.0 Multimedia audio controller: Intel Corporation Celeron/Pentium SIlver Processor High Definition Audio (Rev 06)In Windows I had the same problem of no sound (Before Install Ubuntu I thought that would have been a good idea to try with reinstall windows) the solution was just install oficial drivers from the page but are only for windows, then in the next link you can see what the laptop is and the drivers that solved the problem for windows. (Maybe you should to translate the page)
