title: OpenAL play sound, dealloc one instance, all the other's sound dispeared?
body: <p>I use OpenAL to play sound from network streaming in my NPAPI plugin (browser plugin). When I open more than one browser's tab, I close one of the tabs, the others' sound also dispeared. Anyone could give me some help? Or anyone can give me some advice for playing stream audio, such as audio from mic or such devices. When I use audio queue service, it still cannot surport multi instances. For work's reason, I cannot paste my code in there, sorry about that. I use OpenAL some way as Apple's Developer's example - oalTouch, the link is

  <p>I use the system default device to play sound, which means I use alcOpenDevice(NULL) to open the device.</p>
