[PyQt] Asynchronous QSound.isAvailable()?

I'm having a problem I don't know how to address. Just plain completely at a
The issue: on Linux, when the NAS sound server isn't installed (which is the
case on most distros nowadays), QSound.isAvailable() blocks for several
seconds before returning. Since it runs in the main thread, it blocks the UI
I've tried to poll for sound availability in a different thread, and then
another problem occurs:
QObject: Cannot create children for a parent that is in a different thread.
(Parent is Application(0x26ba030), parent's thread is QThread(0x279d510),
current thread is EnginePollerThread(0x2b22040)
EnginePollerThread is the QThread subclass where I call QSound.isAvailable()
Apparently, whatever object the static method isAvailable() uses is parented
to the main thread, and I'm at a loss as to how to reparent it, or otherwise
make the warning go away.
I'm thus looking for a mean, any mean, to run QSound.isAvailable()
asynchronously. Any pointer, anyone?
