You have the full HDMI interface enabled, which includes the audio signals. You either need to load the cape-universaln overlay that doesn't try to grab the audio lines, or disable HDMI (which allows the HDMIN overlay without audio to load, leaving the audio pins free for your use). I need to make the code smarter so it looks to see if HDMI or HDMIN is loaded and selects the proper overlay automatically. > I am not concerned with HDMI at all so I am more than willing to turn that > off if need be but I'm not 100% on where to do that. Edit /boot/uboot/uEnv.txt, and look for the optargs= line. -- Charles Steinkuehler [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
