Initially, the built-in speakers were working on Linux Mint, but then they stopped, so I thought it was a good opportunity to try Ubuntu. However, even on Ubuntu, I can’t hear any audio from the built-in speakers, not even in a live session. Currently, sounds from built-in speakers works when I install windows, meanwhile I can have sound on Ubuntu only with my headphones (in a perfect way).
When I install Windows, the audio starts working only after I manually download and install the drivers from Acer’s website on the specific page for my PC model.
I think I’ve already spent at least 10 hours trying to fix this. I’ve tried everything I could find online, including switching to older kernels or even changing OS types, such as Debian or older versions of Ubuntu and Linux Mint.
The really incredible thing is that when I first installed Linux Mint, everything worked fine. Then, two weeks ago, the speakers suddenly stopped working, and since then—nothing. Even reverting to the original version I had downloaded, where everything used to work, was useless.
