I am trying to develop a Jetson program which will output an audio signal to a filtering system. This signal will need to be analog, so the digital audio output of the Jetson will need to be passed to a sound card which can preform the digital to analog conversion. This signal will not be a typical sound signal, and will need a sampling rate in the 500kSamp/s range. I was wondering if anybody has any experience connecting the Jetson to a sound card, and could provide some device recommendations. I am looking for a plug and play solution which will keep this process fairly simple.
