Beaglebone audio

   Can we connect the audio speakers with usb on beaglebone

Why not?

do u mean external sound card speaker? or speakers that draw power from usb? if power is not exceeding 500mA and u have driver suport in your own kernel.

Thanks for you reply.can u tell me the name of the .c file

normally u do make menuconfig to enable specific audio driver in the kernel, because most audio drivers are already existed in kernel source.

yes your right!!!i did that!!my dought is that the connection if with
the usb so i just want to understand the driver how its is wriiten.
