[arm-allstar] Tx Audio broken distorted

[Tom Eaton]

Node started having distorted audio on TX side only rx ok and across
internet ok, tried  different transmitter, then new fob, and pi, no change.
Changed SD card and audio now ok.
What could it be in HAMVOIP that could have caused this, and can it be
fixed or just start over with new SD card.

It is running latest ver. as of last week when i did update.
