ALSA : on
CODECS : on
CUPS : on
DEBUG : off
DRIVER : on
KERBEROS : on
PULSEAUDIO : off
SNDIO : off
TEST : off
.
I also rebuilt any audio dependencies with default options (mostly turning off sndio), but the result is the same.
I also played with the sampling rate in pulseaudio, (up to 96000 and down to 22000), but the crackling in firefox got worse, especially at 96000.
