I am trying to play audio on OMAP5 EVM, but i am not able to play any.

OMAP5 board specification:

Kernel: 3.8.13-g2c871a8, gl-sdk 6.04

please help me get audio playing on OMAP5 EVM.

below i am copying my observation on the board, when i run few commands related to alsa.

cat /etc/asound.conf
# default Arago configuration -> this is the only line in the asound.conf file

"amixer scontrols" shows nothing.

"amixer sset Headphone 100%+" shows the below line as response
#amixer: Unable to find simple control 'Headphone',0

"gst-launch-0.10 audiotestsrc ! alsasink device=hw:1,0" shows the below response

  target #  amixer sset -c 1 'Aux FM',0 7
  target #  amixer sset -c 1 'AUDUL Media',0 149
  target #  amixer sset -c 1 'Capture',0 4

Thanks a lot Yordan.

With these settings audio works on OMAP5 now.
