Do you want:
- To capture/record audio?
- To output/produce audio?
What kind of audio? Buzzer tones? Music?
Do you have external memory available?
Is there an audio driver and amplifier available already on your hardware?
If you describe your goal with more details, there's a better chance that readers can help you.

Bruno

Please take a look at the usb_host_audio example using SD card FAT file system. The example can be found under <TivaWare_Installation>\examples\boards\dk-tm4c123g\usb_host_audio. This example application demonstrates playing .wav files from an SD card that is formatted with a FAT file system using USB host audio class

Vo,

Look at this file:

www.ti.com/.../spmu360a.pdf

It is the DK-TM4C129X development kit manual, with full schematics. This contains two circuit parts that you can use:

- How to connect an SD card into a TM4C micro;

- How to connect a TM4C micro into an amplifier for driving a speaker.

Then, for the software part, AFTER you have your hardware sorted out and confirmed, you can refer to the example mentioned here earlier.

Regards

Bruno
