Audio Codec cs42888 not working in SabreAuto reference board running Android 5.1

I am working on playing audio using its audio-codec cs42888 from Sabre-auto quad rev A running android 5.0

When i am checking the available cards it is showing as

root@sabreauto_6q:/ # cat /proc/asound/cards

0 [cs42888audio ]: cs42888-audio - cs42888-audio

	cs42888-audio
1 [imxspdif	]: imx-spdif - imx-spdif
	imx-spdif
2 [imxhdmisoc	]: imx-hdmi-soc - imx-hdmi-soc
	imx-hdmi-soc

i am unable to play audio using tinyalsa.

This is the available audio devices as shown

root@sabreauto_6q:/proc/asound/cs42888audio # ls

pcm0c

pcm0p

pcm1c

pcm1p

My command is :

tinyplay check.wav -D 0 -d 1 -p 8000 -n 8 it is showing that the audio is playing

Playing sample: 2 ch, 44100 hz, 16 bit

But I am not able to hear anything from AOUT. I am suspecting that there may be some audio routing issue. Can anyone explain me how the routing is done in Sabreauto running Android 5.1.

Thanks

Deepika
