I tried loading the module like this
pactl load-module module-sine
It sounds terrible! Lots of clicks and pops on top of the sine sound
I'm running this environment
$ uname Linux vitalsine3h 3.10.29+ #636 PREEMPT Sun Feb 9 19:58:58 GMT 2014 armv6l GNU/Linux $ pactl --version pactl 2.0 Compiled with libpulse 2.0.0 Linked with libpulse 2.0.0
I've also tried building pulseaudio 4
$ ./pactl --version pactl 4.99.3-4-g3cc4 Compiled with libpulse 4.99.0 Linked with libpulse 4.99.0
Which sounds very similar.
So how can I get a nice sine wave from pulseaudio?
