The MAS 3507 chip doesn`t support the lower rates often used for streaming. (Just looking at the data sheet ..looks like 32kbit\s @32khz is the minimum it supports for mp3 format. ). Unfortunatly, it`s a hardware limit..
Maybe this is the same for the Delfina users here??? dunno what DSP it uses.
The only work around for this is to automatically spot a low rate stream and automatically switch to Mpega& AHI..
Maybe something like a minimum hardware rate in the Streamer prefs
