I have a problem with Skype 4.2 during the Test Call that I don't think it matters on client side, but during the test call after the recording and then playback the audio is crackling.

Now I fixed Audacity with the same problem with the package pulseaudio-module-jack and the skipping and crackling in my records was gone afterwards.

I have tried these

high-priority = yes

nice-level = -11

realtime-scheduling = yes

realtime-priority = 5

resample-method = src-sinc-best-quality

But it results in no sound from Pulseaudio on reboot, so I have to comment out the first four and reset the resample-method to speex-float-1.

I did gedit the PULSE_LATENCY_MSEC=60 to PULSE_LATENCY_MSEC=30 and still crackling.

And yes, I have removed tsched=0 from the line load-module module-udev-detect and load-module module-detect and still same thing.

Any help is great at this point.
