GRECORD sets the incorrect channel (mono/stereo) when recording mono. the 
problem is a local variable that is the same name as a global.  the global 
channel value is corrupted with the ESD_STEREO definition (bit field not a 
binary 0/1 value).  problem appears after playing back recorded data, the 
audio is distorted.

patch for grec.c in GRECORD 0.3.4:
