==Better Pulseaudio Sound Quality==
 
Edit /etc/pulse/daemon.conf:
 
gksudo gedit /etc/pulse/daemon.conf
 
Find the following line:
 
resample-method = speex-float-1
 
You can change the resampler to any of the following, listed in descending order, from highest quality to lowest quality (and therefore, CPU usage):
 
* src-sinc-best-quality, src-sinc-medium-quality, src-sinc-fastest, speex-float-{10-0}, speex-fixed-{10-0}, ffmpeg, src-zero-order-hold, src-linear, trivial
 
  
Now reboot and enjoy.
