Problem: Audio from the mic to the HP on the same slave running bi-direct

Hi great people at TI!

I get audio from the input(mic) onto the output(hp) on the same slave headset EVB, even if the master is not on. This seems to be only in bidirectional mode

How can i avoid getting output from the input of the same Headset board?

My setup:

(connected mic)      mic in _______________              Master disconnected and turned off

                                                |    slave     HS evb |    

(connected HP)        hp out_______________               Slave running  bidirectional mode

(Problem: the audio is amplified from the mic to the HP)


Hope this makes it clear, although the drawing might have been smør på flesk.... :P


Regards,


Hans
