8bit pcm does not give a good quality. Perhaps it's 8bit g711 (pcmu or pcma).
In mediastreamer2/src
you need to modify one of the soundcard reader/writer (alsa.c or oss.c, 
depending on whether you use alsa or old oss drivers), and the connection of 
graph done in audiostream.c to insert the proper decoder to pcm 16 bit if the 
samples returned by the audio device are pcmu or pcma.
