Poor audio and missing audio driver issues on my new laptop (Asus Duo), searched the net for the solution and found all kinds of convoluted ways to "fix/solve..". They didn't smell right. The Linux way: "apt search cirrus" oh, there it is: "firmware-cirrus". "apt install firmware-cirrus" then reboot. dmesg no longer gives a long list of missing driver firmware and the sound quality got better. Too many newbies givong bad advice. Loudly. #debian #asus
