Subject: [PATCH] MLK-14935: ASoC: fsl_sai: Fix mixing initialization data with
|
|
actual audio samples
|
|
|
|
When starting a playback the initialization data used to reduce underruns
|
|
was send to the transmit data register after the DMA requests were enabled.
|
|
This patch moves the initialization phase before enabling the DMA so the
|
|
data is transmitted in correct order.
