Well just because you have something does not mean you have to use it. Your
choice. As for the Allstar vs Echolink audio differences I see nothing at
the Pi or FOB end that would cause that. Allstar as you know has two ends
and the effects you are hearing could come from the other end or be
tailored through radios at your end. The G726 codec is the standard one
used but many use the ulaw codec which is higher bandwidth. There is not a
tremendous difference in quality between them. The stock Hamvoip code will
except G726, ILBC, ULAW, or GSM and others if you configure them. This is
determined at time of connection in a priority fashion. You can enforce
only a certain incoming codec but that locks out users that don't have that
particular codec in place. Lets face it Allstar is about the best audio you
are going to get followed by IRLP and Echolink. All of these are many steps
above the current digital RF formats which stink in audio quality. Also
remember the radio you are listening on can tailor the audio and it is
going through two radios, the node radio and the destination radio. A
radioless node with a good speaker would tell you the true story. You can
also hook up an audio amplifier with a good speaker to the output of the
FOB.
