Revision B1

Redesign of the Audio cape to lower cost, for compatibility with the BeagleBone Black, and to switch to the TLV320AIC3104 codec.

Software Support & Compatibility

The device tree overlay is available at the bottom of this page. Please note, the current Angstrom build lacks kernel patches for the audio codec used on this cape, if you attempt to use it on the Angstrom image you will hear audio at double speed or static. The current Debian images have the required patches and will play audio normally.
