Hi, I have put up a site where I posted my tests on using pulseaudio within the OLPC environment. http://wiki.laptop.org/go/Pulseaudio Please feel free to add and comment. What I am a bit puzzled about is the gstreamer section. When using alsa or native clients I can run pulseaudio with sr=44100Hz on the XO. When it comes to use csound, gstreamer or the sdl-mixer I have to go down to 22kHz and you have to use large buffers in both csound and sdl-mixer to avoid clicking. This seams not to help with gstreamer. When gstreamer is connected you have mostly a click at the beginning of the playback. I changed the fragment settings of the ALSA module of pulseaudio and tried to change the buffer settings in gstreamer as well. gst-launch-0.10 filesrc location=/home/olpc/guitcello.ogg ! oggdemux ! vorbisdec ! audioconvert ! 'buffer-size=2048' add-autoload-sink output module-alsa-sink device=plughw:0,0 rate=22050 sink_name=output fragments=12 fragment_size=1024 No luck so far. More details on the tests can be found on the wiki side. Maybe someone here has an idea what else I could try. Best, Simon
