I am trying to record audio in Xavier NX without utilizing an external device (have reviewed similar post which suggested to use external device for this task). Due to requirements, I need to do such without it.
- I have enabled I2S pins on my board according to this.
- I connected 3.1 mm jack (speaker) to my PC and the other end of this wire was divided into three parts one of which corresponds to signal part and second to ground pin of Xavier.
- Signal part was joined to pin 35 (I2S_FS), 38 (I2S_SDIN), 40 (I2S_SDOUT) and 12 (I2S_CLK) (using breadboard) of Xavier (brute-forcing).
- Played audio file in PC and ran arecord command in terminal according to docs’ Capture guidelines.
Resulting audio file gives noisy signal.
Am I doing something wrong? How can I achieve this?
Also, I have available an audio panel header. How can I use it to do this if possible?
