[SOLVED]Problems with ALSA, GStreamer, Java + PulseAudio

Hi, I've been having problems with my sound congfiguration. I am trying to play mp3 songs through vlc or gmusicbrowser, and both are experiencing problems. My sound is working, because I am able to hear sound from Firefox. However when I try to play a mp3 on gmusicbrowser I recieve an error message that says

Playing error : Configured audiosink sink0 is not working. at /usr/bin/../share/gmusicbrowser/gmusicbrowser_gstreamer-0.10.pm line 137.

.

VLC will play the same Mp3, but it will not produce sound despite ALSA being set as the audio output for vlc. I have gstreamer installed and lame. Maybe Gstreamer or ALSA is not configured properly? I've been searching all day and haven't been able to find a solution.

I noticed that the speaker-test will not work either

speaker-test 1.0.28

Playback device is default
Stream parameters are 48000Hz, S16_LE, 1 channels
Using 16 octaves of pink noise
Playback open error: -2,No such file or directory

Thanks in advanced to anyone that is able to help

What have you tried to do to fix this so far? Have you searched the forums here? I seem to recall a thread or two on the "No such file or directory" problem that may help you out.

Re: [SOLVED]Problems with ALSA, GStreamer, Java + PulseAudio

I was able to fix the playing of the Mp3s in gmusicbrowser and vlc by installing pulseaudio. And I have searched quite a bit on the threads that mention "No such file or directory" and I am unable to find anything that helped my problem.  I noticed I can run speaker-test and aplay if i specify hw0.0 as my device. Does this mean my default device is not set properly?

I am also having trouble getting Java to use pulseaudio, is there a config file I need to edit to get java to use pulseaudio?

Java doesn't have direct pulseaudio support, you can however install pulseaudio-alsa and the alsa-plugins in order to have a configuration file which sets ALSA programs to use the  pulseaudio plugin.

Re: [SOLVED]Problems with ALSA, GStreamer, Java + PulseAudio

Hey thanks a lot! I have pulseaudio-alsa and alsa-plugins installed, however my Java application is still not using pulseaudio. Speaker-test works properly now.

And i added these two lines to the top of /etc/pulse/default.pa

2 load-module module-alsa-sink device=hw:0,0
3 set-default-sink 0

I am unable to get the Java application to use pulseaudio, by using a bash script to wrap java with padsp

#!/bin/bash
padsp /usr/lib/jvm/java-7-openjdk/jre/bin/java.bin "$@"

I also noticed that if Java is running, then other sound does not work (such as flash or gmusicbrowser).

Any thoughts? I believe if I was able to force java to pulseaudio it would fix my problem. I have the pulseaudio-alsa and alsa-plugins installed, so I'm unsure of why java won't use pulseaudio.

I am unable to locate libpulse-java.so or pulse-java.jar, that is mentioned here.

Re: [SOLVED]Problems with ALSA, GStreamer, Java + PulseAudio

What are you exactly trying to run? Try with Java 8 from what I see it supports pulse now, the mail you posted is from ages ago it shouldn't be relevant anymore with neither java-7 nor java-8, also the alsa sink load shouldn't be necessary but if it doesn't break anything I don't think it harms anything.  You shouldn't be using apulse if you are actually using pulseaudio now, so it may be beneficial to remove it
