Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.. It's 100% free, no registration required.

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:

Would it be possible to get the same output above from one of the systems that hasn't been allowed to upgrade yet, but still has functioning sound? Due to the differences in hardware it a little apples to oranges comparison of what you've provided so far. –  slm May 18 '13 at 6:45
    
@slm I don't have two reports like that for identical hardware where one (updated) fails and the other (not updated) works. We were in the process of gathering all that info. Each machine is at a different location and the operators have to grant us remote access. Time consuming. –  MountainX May 18 '13 at 18:32
    
@slm I came up with a workaround: don't use Java sound at all. I decided to make a system call and execute a shell command to play notification sounds via mplayer. It works in all situations we have tested. Our software only runs on Linux anyway, so maybe this isn't so bad... ? –  MountainX May 18 '13 at 18:34
    
If it works it works. I have a system with that ICH6 chipset that uses that same snd_intel8x0 kernel driver and it's always been a pain. Feel free to post back if you're interested in pursuing this. What method were you playing the sound before you switched to mplayer? –  slm May 18 '13 at 18:56
    
I previously obtained the best results for playing sound in Java on Linux with the sun.audio.AudioStream and sun.audio.AudioPlayer. Those are "internal" classes and not recommended, but they worked better than anything else for me (for many years). Until the problem that prompted this question. My new solution is just this: Runtime.getRuntime().exec(mediaPlayerCommand + fileName); –  MountainX May 18 '13 at 22:41

For the media player, I can use play on OpenSuse or mplayer on Ubuntu. I just place that command in my configuration file on the target OS and it works really well.
