Polling for presence of soundcard


What would be the best way to poll for the presence of the soundcard, i.e. regularly ask if it is attached and ready to work (for instance a USB soundcard that can be attached) ?

I tried doing it via a Timer that polls checks every 3 seconds via setAudioDevice(), but it seemed to block for a long time, so the whole GUI Thread was blocked.


Trying to open a device is likely to be very slow - maybe just see if it exists with AudioIODeviceType::getDeviceNames ?


That doesn’t work with ASIO devices, they’re always listed, even if not connected… Any other trick (maybe special trick for ASIO Devices?) ?


Hmm, yes, that’d be a problem for ASIO. Can’t think of any quick tricks you could use…
