setMono() command

[drpepperoni1960]

When I issue the setMono(true) command the audio becomes mono as it should. After this action I issue the isStereo() command it outputs a 'true' value, expecting a 'false' here. When I issue the setMono(false) the audio becomes stereo, and the isStereo() command reports, as suspected a 'true'. Hooked up my labatory FM transmitter, set it to mono and the outcome of isStereo() commands reports a 'false' and a 'true' when the transmitter is set to stereo. It looks like that isStereo() command reports the status of the station received and not the status of RDA audio setting. Can you confirm this or am I doing something wrong?
