Our Java application plays short notification sounds periodically (in response to user actions). On some hardward, our application will lock up after the 3rd or 4th short sound. We have to pkill java to recover.
We have the application installed on around 40 computers. All are running Linux. Half have Kubuntu 12.04 installed, half have Linux Mint 11 installed. All the Linux Mint 11 machines work fine and the Java app plays sound without locking up.
Initially (from the release of 12.04) all the Kubuntu machines also worked fine.
At some point, after an update, the Kubuntu machines started locking up when sound was played. If we turn off the sound notification option in our application, that is a workaround. The app will not lock up. But users want the sound.
When we discovered the problem, we stopped running updates on the Kubuntu machines and all those without updates (from months ago) continue to play sound from our app without the app freezing.
Even on the updated Kubuntu machines, lock up problem does not occur on all hardware. For example, on a Thinkpad X220 tablet, sound in our app works without problems. But on a ThinkPad E430, enabling sound in our app causes our app to freeze.
We cannot discover the pattern. What is causing the lockups on a recent Linux and some hardware while the older Linux is fine on all hardware we use?
Here's the info on some hardware where we do have the problem:
