Recording directly with arecord works, but using pulseaudio (skype, audacity) has crackling noise.
Workaround is to disable timer based scheduling in /etc/pulse/default.pa AND setting
default-fragments = 4 default-fragment-size-msec = 90 (or higher, lower still produces noise)
in daemon.conf. Total hw buffer size is 371 ms (according to pulseaudio -vvv > pulse.log)
Using parecord funnilly works.
