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.
Code: Select all
pi@raspberrypi:~$ speaker-test -c 1 -t sine speaker-test 1.1.3 Playback device is default Stream parameters are 48000Hz, S16_LE, 1 channels Sine wave rate is 440.0000Hz
Thanks, is there an official way to know when a dev branch is merged to Raspbian?
