I bet that everyone here has heard about Linux. However, only a few can use it because their hardware doesn't work with Linux.
In my case, I want to use Ubuntu 21.10 on my laptop, Acer Swift 5 - SF514-52T, but I can't because there's no sound coming out of the HDMI port. I have filed this issue here.
I also can't connect my Bluetooth headset, Sony WH-CH710N, at all. The headset paired successfully but it just won't connect. I believe that this could be solved using the method provided here but I didn't have a chance to try it yet.
In fact, I had tried to run Linux on this laptop since Ubuntu 19.04 came out but fail because the integrated mic didn't work at all. Fortunately, this issue is fixed on Ubuntu 21.10.
Nevertheless, the sound system on Linux is a mess...
Linux will not succeed in the desktop market unless it works on most laptops considering that laptops already sell nearly 3 times more than PCs.
Hey, Linux, see you again in Ubuntu 22.04 LTS, KDE neon, or SteamOS 3.0!
