Re: [beagleboard] Audio Cape and Debian
Well, what ever I did, I fixed when I only disabled BB-BONELT-HDM (rather than both). Things are working well now. Thanks so much for the help.

I can only imagine that you must have some typo in uEnv.txt, because nothing you did will affect the SDCard. Maybe you should recreate your SDCard and update the uEnv.txt file on the boot partition of the SDCard.

[beagleboard] Re: Audio Cape and Debian
I got mine from http://boardzoo.com/index.php/new-products/bone-audio.html#.U2_-VFd7_uw boardzoo.com Cost $29.95 Few other notes: I will likely need to modify this board to include an audio amp to drive a speaker and an on-board mic. I tried to play audio directly from Java - don't think it's gonna work without some indepth knowledge of the Linux and the Java audio. My most likely solution will be to simply execute an external program (most likely madplay). aplay will only play wav files, I would rather use mp3 due to space. I've installed maplay using apt-get install madplay (i've tried mpg123 - but didn't seem to work and did not want to fight that battle Good luck. I know very little of Linux, so this was a bit frustrating form me, I hope my notes help I'm not entirely sure yet, but think I will execute (from Java) lame to record.
