[Openal] Re: OpenAL Soft performance question

[Troy Yee]

The app uses dmix primarily (occasionally something will go to a specific hardware device).  Haven't seen any output at console and nothing is getting triggered by error return codes.

If I use aplay to play a sound when the app is in this state, the sound plays fine.  Would it make sense that the app would start working correctly after resuming from suspended state (Ctl-Z in console followed by fg) if it were an overflow issue?

Troy.
