Sound doesn't work under ALSA without aoss

[Reuben Thomas]

When I try to use a Java program that uses sound (I tried with "processing" from processing.org), Java complains that the sound device cannot be opened:

==== JavaSound Minim Error ====
==== Couldn't open the line: Audio Device Unavailable

This error seems to be a generic Java error, not specific to "processing".

I am using ALSA for sound (i.e. I don't have PulseAudio running), and everything else (mpd, Sonata, Flash, sox, mplayer, vlc, xine &c.) seems to work fine. If I run processing with "aoss processing" then it works fine, but as far as I can see it should work either with ALSA or with PulseAudio.

I have the same problem if I use sun-java6 rather than openjdk.

please could you recheck this in karmic, and/or with the packages from

I now use PulseAudio, with which I don't have this problem. Is there
some way I can temporarily disable PulseAudio to check? I'd rather not
remove PA from my system, as it took some effort to make it work!

rechecked that this works with pulseaudio in lucid. I'll close this report after the lucid release. pulseaudio is now used by default on the desktop

I have this problem on lucid with sun-java6. No problem with openjdk, but it seems that the controlP5 library that is a Processing extension will only work correctly with sun-java6.

[Gerrit Niezen (gerrit-niezen)]

OK, this bug seems related: https://bugs.launchpad.net/ubuntu/+source/sun-java6/+bug/457144

So the options are to either to copy libpulse-java.so and pulse-java.jar from openjdk to sun-java6, or use openjdk.
