Hi,
I'm working on OMAP4430 custom board with linux kernel 3.15(with device tree support) bring up. I'm having a problem with handsfree (Ext Spk) on TWL6040 audio codec, where Earphone, headset, haedset -mic, main-mic, and vibrator are working fine. When enabling handsfree with "amixer" control commands and play an audio file by means of "aplay" tool, I could hear only "pop" sound from handsfree. Could you please help me to resolve this issue?
Below are boot logs and commands used,
