Other Parts Discussed in Thread: TWL6040

Hi, is just that i have a Pandaboard ES and i would like to connect the handsfree speaker connector to a speaker (to use the 1.5W amplification from the TWL6040 audio codec), is that possible?, or do i have to decode the output from 13 and 15 pins from the J6 expansion connector from pandaboard, how can i get the an amplified audio output to speaker from that connector (J6)?. thanks.

    my problem is solved, it was an issue with the speakers but it doesnt need any other kind of connection, just the speakers.

    Hi, have you checked the signal from those output pins of the J6 connector with an oscilloscope to see if there is a signal?, if you do have the signal, check the speakers, my problem was that the frequency of that signal was high (352.58kHz) and apparently the speakers that i was using couldn't response to that signal, so i used another ones of 1 Watt and i finally got the sound, with the handsfree (+) and ground or handsfree (-) and ground, you get the half of the signal than if you connect both cables of the speaker, one cable to handsfree (+) and the other cable to handsfree (-).
