Hi,

I am trying to play the audio files from OMAP5912 OSK by connecting an amplifier and speakers to the kit at HEADPHONE OUT end. But the output sound is very less whereas I am able to get high sounds when playing from a CD player or tape recorder.

I think there is an impedance mismatch between OMAP5912 and the amplifier which I am using. Any body Please help me in providing the audio specifications of the processor like output impedance, etc.

Thanking you

With regards
Azharuddin

You should have OSK5912 schematic if you have a board. If not, have a look to section 5.6 (page 48) of

TLV320AIC23 datasheet you can get at
