I have a Java Forex trading platform that runs on my Kubuntu Linux (KDE) desktop.
There is an alert feature in the trading software and when I run the program, my sound card is unavailable to other programs. Usually this is not the case, when running other sound programs (players and such), as I have been using ALSA.
My guess is that the java program is using something other than ALSA (maybe opensound).
Does that sound right (excuse the pun)?
If so, is there a way to change this within Java, or does the program itself specify which sound device to use? My desktop default is set to ALSA.
