As you have mentioned, looks like I am having issues with configuring 
the sound card through PulseAudio.
Yes, I am able to play using aplay.

I am gonna try and give you all the details i have.

1.	I am building a custom image for embedded hardware using yocto/poky 
build system.

2.	Before installing pulseaudio:

a.	aplay executes(without error) without giving any audio
b.	After passing following amixer commands it starts to produce audio 
too.

amixer cset name='SLIMBUS_0_RX Audio Mixer MultiMedia1' '1'
amixer cset name='SLIM RX0 MUX' 'AIF_MIX1_PB'
amixer cset name='SLIM RX1 MUX' 'AIF_MIX1_PB'
amixer cset name='SLIM_0_RX Channels' 'Two'
amixer cset name='RX INT7_1 MIX1 INP0' 'RX0'
amixer cset name='RX INT8_1 MIX1 INP0' 'RX1'
amixer cset name='SpkrLeft COMP Switch' '1'
amixer cset name='SpkrRight COMP Switch' '1'
amixer cset name='SpkrLeft BOOST Switch' '1'
amixer cset name='SpkrRight BOOST Switch' '1'
amixer cset name='SpkrLeft VISENSE Switch' '1'
amixer cset name='SpkrRight VISENSE Switch' '1'
amixer cset name='SpkrLeft SWR DAC_Port Switch' '1'
amixer cset name='SpkrRight SWR DAC_Port Switch' '1'

aplay -D hw:0,0 Alesis-Fusion-Voice-Oohs-C4.wav
aplay Alesis-Fusion-Voice-Oohs-C4.wav

3.	Installing pulseaudio:

I am installing pulseaudio using bitbake recipe.
I have pulseaudio version 6.0.
I am adding following packages in image.

IMAGE_INSTALL += "lib32-libpulse"
IMAGE_INSTALL += "lib32-libpulsecommon"
IMAGE_INSTALL += "lib32-libpulsecore"
IMAGE_INSTALL += "lib32-libpulse-mainloop-glib"
IMAGE_INSTALL += "lib32-pulseaudio"
IMAGE_INSTALL += "lib32-pulseaudio-server"
IMAGE_INSTALL += "lib32-pulseaudio-dbg"
IMAGE_INSTALL += "lib32-pulseaudio-doc"
IMAGE_INSTALL += "lib32-pulseaudio-lib-alsa-util"
IMAGE_INSTALL += "lib32-pulseaudio-lib-cli"
IMAGE_INSTALL += "lib32-pulseaudio-lib-protocol-cli"
IMAGE_INSTALL += "lib32-pulseaudio-lib-protocol-native"
IMAGE_INSTALL += "lib32-pulseaudio-lib-protocol-simple"
IMAGE_INSTALL += "lib32-pulseaudio-misc"
IMAGE_INSTALL += "lib32-pulseaudio-module-cli"
IMAGE_INSTALL += "lib32-pulseaudio-module-cli-protocol-tcp"
IMAGE_INSTALL += "lib32-pulseaudio-module-cli-protocol-unix"
IMAGE_INSTALL += "lib32-pulseaudio-module-alsa-card"
IMAGE_INSTALL += "lib32-pulseaudio-module-alsa-sink"
IMAGE_INSTALL += "lib32-pulseaudio-module-alsa-source"
IMAGE_INSTALL += "lib32-pulseaudio-module-always-sink"
IMAGE_INSTALL += "lib32-pulseaudio-module-augment-properties"
IMAGE_INSTALL += "lib32-pulseaudio-module-card-restore"
IMAGE_INSTALL += "lib32-libpulse-simple"
IMAGE_INSTALL += "lib32-pulseaudio-module-dbus-protocol"
IMAGE_INSTALL += "lib32-pulseaudio-module-device-manager"
IMAGE_INSTALL += "lib32-pulseaudio-module-device-restore"

4.	After installing pulseaudio:

(if pulseaudio is not running)
/ # aplay /data/8khz_mono.wav

5.	a more detailed verbose log for "pulseaudio -vv" is attched in 
previous mail.
highlight from that are bellow

6.	I am also attaching the output of "pactl list".
"pactl list cards" detects no cards. Does that mean pulseaudio has no 
information about the card?

7.	pactl output

8.	Additional information may be useful.
"gst-play-1.0 audio.wav" does produce audio for in both conditions 
before installing pulseaudio as well as after installing pulseaudio.


thanks for your help really appreciate it.
