I've used Hydrogen on Linux without problem. Trying it on Windows. By default I get no sound at all. I cannot find anything in docs or here in the forum about how to configure the Audio System (i.e. under Preferences->Audio System). To my knowledge, ALSA , JACK, and OSS do not run on Windows, so I assume PortAudio or choosing Auto are my choices. Neither do anything.
Any help is appreciated. Thanks
