I don't know about the latest Raspbian release but here's how to try it, from the first post: "add audio_pwm_mode=2 to /boot/config.txt and reboot." I imagine this works if your firmware is at least as new as that first post which was from Wed 11 Oct 2017. Check with "uname -v". If it's older, first do "sudo apt-get update && sudo apt-get -y dist-upgrade" and try again. If it's still too old, you might or might not try "sudo rpi-update" which goes well 99% of the time. If you do and it does go well, then it will definitely work.
Hi all, many thanks to jdb for this driver. Is there a way to use ONLY this driver without using rpi-update? I don't want to break my system in the case that something has a regression.
Thanks, is there an official way to know when a dev branch is merged to Raspbian?
Ok, so I can't know if the latest 4.9.35-v7+ kernel has this new driver or not. If I use audio_pwm_mode=2 option I still hear "HISS" from speaker, so, maybe not
Does 3B+ have same hiss on analog like RPI2 for example?
Btw. could you ***PLEASE*** look into this in Rpi4 PROTOTYPE? We have fun for years with fixing A/V out on older models...
