SubSonic jukebox output broken in Debian 8 (Ubuntu as well?)

Postby benito » Sat Apr 30, 2016 2:41 am

KEYWORDS: Sunsonic Linux Debian Ubuntu no jukebox sound output jukebox: javax.sound.sampled.LineUnavailableException


I installed SubSonic, following the instructions on the subsonic website.
First, install Java: sudo apt-get install openjdk-7-jre
Download the Subsonic .deb package and install it: sudo dpkg -i subsonic-x.x.deb

All went to plan, and even Android playback does work, but Jukebox output errors out and there is no sound output.

Some background:
I had Subsonic working well with jukebox output under Debian 7 (using Sun java package).
Initially I tried Subsonic version 5.3.beta2 (the same version that worked on Debian7) ; no jukebox output, so I upgraded to latest 6.0.beta2, still no output.

I have a suspicion that Java version is to blame, but cannot prove it, nor know what to try next. ( I did as I was told to install)

P.S. Sun Java is no longer available for install on Debian / Ubuntu.


Here are the technical details:

[Solved] SubSonic jukebox output broken in Debian 8

Postby benito » Sun May 01, 2016 6:32 am

I found the solution myself, with a little experimentation.
It seems that the Java implementation was the issue.

OpenJDK cannot produce sound output under Debian (and Ubuntu as well I suspect).
(True at least of OpenJDK 2.6.4 circa May 2016)

I replaced OpenJDK with Oracle Java and sound output is good.
Oracle Java (Formerly Sun Java) is no longer a package included with Debian or Ubuntu, but there are sources for .DEB packages, so install is pretty easy.

First, remove OpenJDK, so as not to clash with Oracle Java.
Code: Select all
sudo apt-get purge openjdk-7-jre
sudo apt-get autoremove


Then install Oracle Java (v1.8.0_91-b14 at time of writing)

Code: Select all
su -
echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main" | tee /etc/apt/sources.list.d/webupd8team-java.list
echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main" | tee -a /etc/apt/sources.list.d/webupd8team-java.list
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys EEA14886
apt-get update
apt-get install oracle-java8-installer


et Voila! ce finis.

Sindre, perhaps you may wish to update the instructions for Debian/Ubuntu install with a caveat for those who use Jukebox mode.

I hope this post helps other save time and frustration.

Regards,
Benitio.
