It is here? Or only digital?
It may be possible to do with a connector to the GPIO headers, but there is no built in jack for it on the A10. Another model, the A13 I think, has a standard audio jack (and similar CPU, RAM, etc.).
Thank you for "may be" :-) this not help me :-)
Analogue audio output is via HPOUTR (routed to GPIO 1/18) and HPOUTL (routed to GPIO 1/14)
