jukebox not playing (Ubuntu 12.04, Sun Java 7, tomcat6)

[HanlonsRazor]

Hi Subsonic Forum Gurus,
I'm stuck. I'm hoping someone can help.

Problem Description: When a jukebox player is selected, and songs are played, the playlist fills but no sound is emitted from the audio on the server.
Troubleshooting Steps: See below
Playback Application and version: Subsonic jukebox player
Subsonic Version: 4.6 (build 2583) – December 6, 2011
Server Version: Tomcat/6.0.35, java 1.7.0_04, Linux (59.6 MB / 123.8 MB)
Hardware Platform: Linux (32-bit, x86)
Java Memory Limit: ()
Problem Filename: (All files)
Output from ffmpeg -i: It doesn't matter what file I play, but I'll pick one as a sample:

Note: These same 4 lines will repeat with whatever file I attempt to play, only the filename changes.

Diagnostic things I've tried:
I can play the song through the web player (flash).
I can play the song through the Android app.
I can run the ffmpeg command from the log, and pipe the resulting stream to "aplay", and it plays fine.

Changes I've tried:
I started with openjdk-6, but many people reported that there were known problems with openjdk and jukebox mode, so I installed the Oracle/Sun Java 7 implementation.
Some people reported that things didn't work until they removed openjdk entirely, so I've now removed openjdk entirely.
I've restarted tomcat (countless times, practically after every change).
I've rebooted the server (almost as often as I've restarted tomcat6).
I've purged and reinstalled tomcat6.
I've reinstalled Oracle/Sun Java 7.
I've copied libpulse-java.so and pulse-java.jar from the openjdk implementation into the corresponding lib/i386 and lib/ext locations in the Oracle/Sun JVM implementation (gets me different, but still non-successful behvior, this time with a "javax.sound.sampled.LineUnavailableException" in the log.)
I've updated the sound.properties file in the $JAVA_HOME/lib directory, and returned it to the default.

It LOOKS like ffmpeg is converting the data, but the stream isn't being read - it just sits there. There's no error. I can see the ffmpeg process is still running:

Any help would be appreciated. I've already fought with it for 12+ hours, and searched through so many forums and tried so many things that I don't know what state the packages are in anymore. I can even start over with a fresh Ubuntu install, though that would not be my first choice.

I assume you have read viewtopic.php?f=2&t=8534&hilit=jukebox+ubuntu
If not it might help.

Thanks, but yes - I did see that. The third post in that thread was the main reason I installed Oracle Java 7 in the first place. Of course, this other one (viewtopic.php?f=2&t=9202) suggests that all forms of Java 7 are incompatible with all forms of Subsonic - but I'm still not sure what "incompatible" means, since it seems to work fine for serving music to my Android, or to my laptop using the flash browser.

I'm thinking that maybe I should reinstall Ubuntu 12.04, which will take me back to the default OpenJDK Java 6, then reinstall Oracle Java 7, and then try some more of the suggestions that head down the road of getting the PulseAudio to work right. I actually had it to the point once where it looked like it might be playing, but still there was just no sound coming out. That is, the log messages looked like it was playing songs, and the log entries for the songs on the playlist were spaced apart like they were taking about the right amount of time to play... I still couldn't hear anything, so I figured it was still broken. I tried a few more suggestions, and I went back to having either errors in the log, or hung ffmpg processes that never exit. Later, I noticed that regular audio playback had ceased as well, and discovered that one of the suggestions I had tried had ended up resetting the mixer so that the audio was essentially muted. Since I don't know which change caused that, it might have occurred before the point where I thought it looked like it was working - and maybe it was actually working, but the audio was just turned all the way down.

I haven't had any time to try fixing it during the week, but I'm going to try to start over again tonight.

Did you ever have any luck with this? I'm having the same problem.

I, too, am having this exact same problem. I'm running the same versions of tomcat and subsonic as HanlonsRazor reported... though I haven't yet messed with alternate java installs. Well, not this time, anyway. I recall having this same problem in the past with earlier versions of Ubuntu, and I tried various alternate java installs (from Oracle) with no success.

I seem to recall that the problem is that the sound output device is hard-coded and cannot be changed in the .war installation. Well, I'm eager to get this working, so if anyone has any leads, please let us know!
