The problem is that if I plug in the HDMI, I can *NEVER* use the internal (SGTL5000) audio again, even when I unplug the HDMI. Neither rebooting, nor resetting the board using the switch restores the internal audio. However, if I cycle the power and boot with the HDMI not connected, it works again. -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------
