Regarding Audio Capture on Ti Netra

Hi,

We are using the latest version of the EZSDK 5_05_01_04.

Problem Faced: Audio gaps seen when we use arecord application to record Audio

eg: arecord -Dhw:0,0 -c 2 -f S16_LE -r48000 48KHz.pcm

The Audio is connected to LINE IN of the base EVM, Howewer we see Audio Gaps for other sampling frequency like 44100, 32000 also.

Almost 1-2 gaps are observed for a 5 min duration record.

It would be really helpfull if you can point out the problem related to the Audio Capture.

Regards,

Sudeep
