The trick is disabling PulseAudio’s timer-based scheduling. Fire up the terminal, then type:

su -c "nano /etc/pulse/default.pa"

Look for the line that contains load-module module-udev-detect, and append tsched=0 to it. Now it should look like this:

load-module module-udev-detect tsched=0

Save the buffer and exit the editor, then restart PulseAudio with the following commands:

pulseaudio -k
pulseaudio --start
