I believe that is because there is no onboard audio codec on the BBB as there is on RaspberryPi.

The video over HDMI works fine. I've read through http://elinux.org/Beagleboard:BeagleBoneBlack_HDMI and tried both of the listed resolutions that support audio. I tried each (separately) by adding "optargs=video=HDMI-A-1:1280x720@60" to /boot/uEnv.txt and I can see a change in the displayed resolution when I reboot, but no audio. I started with the 2015-03-01 Debian image from beagleboard.org/latest-images and have been adding packages to it using apt-get. "uname -r" reports "3.8.13-bone70" For testing I'm using mplayer and a FLV video file I know has sound when I play it on my other computers. Not sure what else to try as I am far from a Linux guru and Google searches either produce people saying it cannot be done or people who say it is super easy (but don't explain how they got it to work). I do know that when I run the fbset command I get debian@beaglebone:~$ fbset mode "1920x1080" geometry 1920 1080 1920 1080 16 timings 0 0 0 0 0 0 0 accel true rgba 5/11,6/5,5/0,0/0 endmode which does not appear to list any EDID information, but I don't know what (if anything) I can do about that.
