ESAI_TX_FS and ESAI_TX_CLK signal level after stop audio playback

Question asked by Takayuki Ishii on Dec 6, 2018

Hello community,

 

I'm playing audio/video playback by gstreamer on SABRE-AI + SABRE_BASE board.

OS I tested is a Linux BSP L4.9.11.

But my customers environment is a Android N7.1.2.

 

To stop playback by "Q" or "ESC" key pressed, both ESAI_TX_FS and ESAI_TX_CLK signal level 

will changed by stop timing. Sometime keep Hi level and sometime will go Low level.

It seems that data transfer will be stopped middle of 1 Frame(L+R data).

Is it a normal operation?

 

I think when stopping playback, it stops after transferring the last data and keep

last signal state every time.

Could it do by current BSP?

 

Best regards,

Ishii.
