[Discuss-gnuradio] Stereo FM Radio Redux

[John B. Wood]

Hello, all.  I decided to revisit the implementation of a broadcast 
(88-108 MHz) stereo FM receiver on my Ettus USRP E310. I found the 
attached GRC flow graph on the web (I removed the RDS and waterfall plot 
stuff).  The radio works using the E310 as a USRP source but for some 
reason the audio is mono (left and right channels are the same).  I'm 
running GRC on a computer linked to the E310 (remote mode).  The 
soundcard on the computer can play stereo audio fine, for example, from 
Rhythmbox.  Is something in the flow graph misconfigured  or missing?  
Your time and comment is greatly appreciated.  Sincerely,

                                                       John Wood
