[pulseaudio-discuss] Problems with pulseaudio / asla on PS3

[Kevin Gilbert]

Hi,

I'm trying to get an jukebox application going on a Sony PlayStation3 using 
Qt-Embedded, Phonon and PulseAudio. The application is working well on my KDE-
based laptop where it appears that the application is using Phonon -> ALSA -> 
PulseAudio. But there is no sound from the application when run on the PS3.

BTW, the base software on both systems is Fedora 9 but on the PS3 I'm running 
a kernel downloaded from
 git://git.kernel.org/pub/scm/linux/kernel/git/geoff/ps3-linux.git. The kernel 
has both ALSA and OSS compiled in.

Using the following /etc/pulse/default.pa file I can get output from aplay, 
paplay and mplayer (the latter with "-ao pulse").

=== begin ===
#!/usr/bin/pulseaudio -nF
.nofail
load-sample-lazy pulse-hotplug /usr/share/sounds/startup3.wav
.fail
load-module module-oss device="/dev/dsp" sink_name=output source_name=input
load-module module-hal-detect
load-module module-esound-protocol-unix
load-module module-native-protocol-unix
load-module module-volume-restore
load-module module-default-device-restore
load-module module-rescue-streams
.ifexists /usr/lib/pulse-0.9/modules//module-gconf.so
load-module module-gconf
.endif
=== end ===

(Yes, I realise that I have loaded the OSS module as without it I get no sound 
at all!) The following is the output from the pulseaudio daemon and as you can 
see there are problems with the pulseaudio / alsa interface.

Thanks in advance for any help.
