BeagleBone External Audio Codec

Hi,

what - beside making the hardware - has to be done in principle to add an external audio codec to BeagleBone if a kernel module is already available?

In principle, nothing. Once you've got the hardware and a kernel
driver it should "just work" via the standard ALSA sound interface in
userspace. Of course, the devil is in the details - looking at the
current kernel source there appears to be a driver for the TLV320XX
codecs, but so far I've found that merely enabling the code in the
kernel configuration and calling the setup functions is not sufficient
to get ALSA to recognize the driver. Something is missing and I
haven't figured it out yet.

Hi Eric

thanks for your reply. So I will have to use an USB codec.

May I suggest you to join `alsa-devel`, you will most certainly find a
lot of help there!
