PCM2912A: Buffer over and underruns + glitch

Part Number: PCM2912A

Hello Audio team, 

 

I am reaching out to you on my customer's behalf. Patrick has the following inquiry:

We would like to get some support on the PCA2912A usb codec.

We have implemented the chip in our Android based project.

We have spent several weeks adjusting the applications and BSP to improve but continue to experience buffer over and underruns.

Our device is primarily using a synthesized speech engine to generate TTS audio stream. The glitches in the resulting TTS audio are severe and not something we can ship.

Before we proceed with replacing the codec with a different chip, we would like to see if there is factory support for this chip to help us debug the design.

 

regards,

Rez
