Teensy 3.1 + SmartMatrix + Ethernet (or Wifi) + Audio

[profoX]

Hi, I am relatively new to electronics,
but I am comfortable with programming.

I want to create a 32x32 RGB LED matrix wall,
connected to the internet (Ethernet or Wifi)
to contact a webservice for new content to display.

I was thinking about using these components:

• Teensy 3.1
• SmartMatrix SD shield
• 32x32 RGB LED matrix

Now, I would also like to know whether it would be possible to play raw audio files
using the Audio library together with this configuration.
I am not sure how I should connect a speaker to the Teensy,
or would I have to use the Audio Adaptor?
If so, can both the SmartMatrix SD shield and the Audio Adapter be connected?

Apart from that. The ethernet (or wifi) connection.
Do I need another shield or adaptor for that?
Is it possible?

Thanks in advance for the help.

This is really a question for Louis at PixelMatix (maker of SmartMatrix)

If you can live with mono 12 bit sound, your best path is probably to use the DAC pin. You won't impress any audiophiles, and you can't have stereo, but for casual listening the DAC output sounds quite good. It's best to use with amplified computer speakers. If you want to drive a speaker directly, you'll need to add an amplifier (pretty much the same as what's in amplified computer speakers).
