[pulseaudio-discuss] [PulseAudio] No sound while Testing Pulseaudio on Beagleboard

Hi,

I Pulled the PulseAudio(0.9.22) in Poky. I ported the uImage and rootfs on
to the Beagle board. I have /etc/asound.conf

I started dbus, hal and avahi daemons and created groups also.

star of file-------

#Use PulseAudio Externally
pcm.pulse {
    type pulse
}

ctl.pulse {
    type pulse
}

#Use PulseAudio by default
pcm.!default {
    type pulse
    # If defaults.namehint.showall is set to off in alsa.conf, then this is
    # necessary to make this pcm show up in the list returned by
    # snd_device_name_hint or aplay -L
    hint.description "Default Audio Device"
}
ctl.!default {
    type pulse
}

end of file--------

Loaded all the modules as follows.

modprobe snd_soc_omap3beagle
modprobe snd_soc_omap
modprobe snd_soc_omap-mcbsp
modprobe snd_soc_twl4030


unmuted the sound card


amixer -c 0 cset iface=MIXER,name='Headset Playback Volume' 100
amixer -c 0 cset iface=MIXER,name='HeadsetL Mixer AudioL1' 1

*simple "aplay" without asound.conf is working fine.*
*
*
*But aplay and paplay not woriking with the file "asound.conf" under /etc.*
*I am not getting any errors but there is no sound while playing an audio
file using "aplay" and "paplay"*
*
*
*
*
*my default.pa under /etc/pulse is *

### Load something into the sample cache
#load-sample-lazy x11-bell /usr/share/sounds/gtk-events/activate.wav

### Automatically restore the volume of streams and devices
load-module module-device-restore
load-module module-stream-restore
load-module module-card-restore

### Automatically augment property information from .desktop files
### stored in /usr/share/application
load-module module-augment-properties

### Load audio drivers statically (it's probably better to not load
### these drivers manually, but instead use module-hal-detect --
### see below -- for doing this automatically)
load-module module-alsa-sink device=hw:0
load-module module-alsa-source device=hw:0
#load-module module-oss device="/dev/dsp" sink_name=output source_name=input
#load-module module-oss-mmap device="/dev/dsp" sink_name=output

### Automatically load driver modules depending on the hardware available
.ifexists module-udev-detect.so
load-module module-udev-detect
.else
### Alternatively use the static hardware detection module (for systems that
### lack udev support)
load-module module-detect
.endif

### Automatically load driver modules for Bluetooth hardware
.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover
.endif

### Load several protocols
.ifexists module-esound-protocol-unix.so
load-module module-esound-protocol-unix
.endif
load-module module-native-protocol-unix

### Network access (may be configured with paprefs, so leave this commented
### here if you plan to use paprefs)
#load-module module-esound-protocol-tcp
#load-module module-native-protocol-tcp
#load-module module-zeroconf-publish

### Load the RTP reciever module (also configured via paprefs, see above)
#load-module module-rtp-recv

### Load the RTP sender module (also configured via paprefs, see above)
#load-module module-null-sink sink_name=rtp format=s16be channels=2
rate=44100 description="RTP Multicast Sink"
#load-module module-rtp-send source=rtp.monitor

### Load additional modules from GConf settings. This can be configured with
the paprefs tool.
### Please keep in mind that the modules configured by paprefs might
conflict with manually
### loaded modules.
.ifexists module-gconf.so
.nofail
load-module module-gconf
.fail
.endif

### Automatically restore the default sink/source when changed by the user
during runtime
load-module module-default-device-restore

### Automatically move streams to the default sink if the sink they are
### connected to dies, similar for sources
load-module module-rescue-streams

### Make sure we always have a sink around, even if it is a null sink.
load-module module-always-sink

### Honour intended role device property
load-module module-intended-roles

### Automatically suspend sinks/sources that become idle for too long
load-module module-suspend-on-idle

### If autoexit on idle is enabled we want to make sure we only quit
### when no local session needs us anymore.
load-module module-console-kit

### Enable positioned event sounds
load-module module-position-event-sounds

### Cork music streams when a phone stream is active
load-module module-cork-music-on-phone

# X11 modules should not be started from default.pa so that one daemon
# can be shared by multiple sessions.

### Load X11 bell module
#load-module module-x11-bell sample=bell-windowing-system

### Register ourselves in the X11 session manager
#load-module module-x11-xsmp

### Publish connection data in the X11 root window
#.ifexists module-x11-publish.so
#.nofail
#load-module module-x11-publish

### Make some devices default
#set-default-sink output

Please Can anyone tell is there anything to configure and modify.
There is no sound while i am trying to play an audio file(abc.wav).

Any help will be appreciated.
