[Bug 460530] [NEW] Pulseaudio Java Firefox ALSA inconsistencies

 

Public bug reported:

Description:	Ubuntu 9.10
Release:	9.10
sun-java6-jre 6-15-1

When using the Sun Java 6 JRE, audio from applets within Firefox are not
producing audio through Pulseaudio. For me to reproduce this bug I
perform the following:

1. Pick a software defined radio station from http://www.websdr.org
2. Applet starts, try to tune frequency with buttons or clicking underneath the spectrum

Notes about trying to resolve this:

1. I tried the OpenJDK with the Icedtea plugin. Audio does not work with
Pulseaudio but does work with the ALSA commented settings as per bug
#407299, however, the Javascript -> Java bridge of perhaps this specific
applet become broken, and is probably a separate bug.

2. Tried also to explicitly set the ALSA settings in the comments of the
/etc/java-6-sun/sound.properties as per what is done with the OpenJDK
file like #407299, this does not.

3. Using AOSS or PADSP to launch Firefox hangs, and also hangs when
editing these scripts to include it immediately after the exec line.


Thank you so much for your efforts!
