[PATCH] ASoC: amd: Changing Audio Format does not reflect.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When you run aplay subsequently as below by changing the stream format:

aplay -Dhw:2,0 -c2 -fS16_LE -r48000 /dev/zero -vv -d 5;aplay -Dhw:2,0
-c2 -fS24_LE -r48000 /dev/zero -vv
as a single command, the format gets corrupted and audio does not play.

So clear the ACP_(I2S/BT)TDM_ITER/IRER register when dma stops.
