Thanks but If I use audio_pwm_mode=2 option I still hear "HISS" from speaker, so maybe this driver is not present on the latest kernel as I wrote hereepoch1970 wrote: ↑Sat Jan 20, 2018 3:12 pmI’d recommend you add audio_pwm_mode=2 only.
This is a recent addition, AQ on analog out is truly good with this new driver.
It supports concurrent access, ie 2 (or more) separate programs outputting at the same time.
I’m not sure it is out of beta yet? For me, playing audio only with ALSA works a treat.
EDIT: As offered by jdb in his thread, I would recommend using SKIP_KERNEL=1 rpi-update if you don’t want to upgrade your kernel at the same time. I’ve used recent firmware with an older kernel (on piCore OS) and it just worked fine.
