[alsa-devel] Kernel 5.2.2 - RSpeaker not working - MacBookAir 3,2
Ladies and gentlemen,
I tested alsa on Kernel 5.2.2 on an MacBook Air 3,2 with alsa-lib 1.1.9, fftw 3.3.8, ncurses 6.1. Somehow I was not able to get the right speaker to work. On Kernel 4.19.60 everything works. Same setup different results. Distribution: Arch Linux
