Hello.
I've had various sorts of issues with PulseAudio ever since I started running Ubuntu since almost one year ago. I tend to try DIY instead of asking and so I've had most of the issues resolved. But this one that appeared today is a bitch. I considered replacing PulseAudio with vanilla ALSA but most applicaitons failed to work afterwards. So here I am asking for your kind help.
So as the title says, I cannot record sound while the PulseAudio daemon is running. I use arecord and the result is just silence. Without pulse running, arecord works perfectly.
Here's some possibly useful info:
