I own a rev. A5 freerunner and was seriously affected by the buzz problem. 
After applying the hardware fix the audio quality improved a lot. Before the 
fix there was no chance to use the FR as a phone.

However, the audio quality was never as good as on a friends rev A7 FR 
(without buzz-fix).  I did a lot of experimenting and tweaking with all 
possible audio parameters but the volume has always been either too low or 
distorted. He just uses the default audio configs and has nearly no problems 
with sound quality.

It is definetly worth it if you, or better said your call partner expierences 
a rather loud buzz. The fix will remove that buzz but won't fix other issues 
like rustling, echo or low volume. Those issues can mostly be addressed with 

Hope that helps,
