Audio out

I was thinking about using the Virtex 7 for a project I'm considering but I will need to output some audio and I can not find an audio out port on the board. Does anyone know a way to output an audio stream on the board?

Re: Audio out

Digital or analog? How about spdif over HDMI? Otherwise, there's FMC cards and pmods with various audio codecs and amps.

Re: Audio out

I am planning on analog and want to stay away from the hdmi port if possible. Would it be possible for you to point me to some resources for the FMC or pmods?

Re: Audio out

Ah okay. Sure, just a quick google search reveals:

I seem to recall Maxim having some stuff too.

For what it's worth, the zedboard has a analog devices audio codec on-board.

Re: Audio out

Not sure, but there should be some work to do to run audio via HDMI (transmitter configuration, S/PDIF encoding possibly) so a simple PWM might do to? There are several approaches to perform relatively high qualifty with simple filtering.
