VirtualMIDISynth goes silent when coming out of sleep mode

Hi all,

Hopefully the title says it all-- I've noticed a bug of sorts with my VirtualMIDISynth installation where, if I wake up my computer from sleep mode and try to play a MIDI file (doesn't matter what program-- Windows Media Player, vanBasco's Karaoke Player, you name it) there's no sound whatsoever. The only way for me to work around this problem is by restarting VirtualMIDISynth or by restarting the computer altogether.

I'm using the most recent version of VMS (I first noticed this in version 2.12.8 and upgrading to the latest version didn't help), I have all necessary Windows updates (not sure if that matters here), and this is the only computer I'm having this issue with. Is there a way for me to solve this problem for good? If there is, please let me know.

Thanks in advance!

Well, I suppose that this bug could be strictly related to how audio drivers manage power state changes.

It seems that some of them (like yours) won't reinitialize correclty after sleep, or they require to be re-initialized after power suspension.
None of my test platforms have this behavior: if I press the POWER button the PC goes to sleep then, just after pressing the POWER button again, it wakes back up and (after a few seconds), it resume playing as nothing happened in between 🙄.

Anyway it worths a try to detect Windows power events and force a reinitialization of the audio layer, just to be sure it gets back working without problems.

The attached version adds this experimental feature, please check it out and report if it works correctly.
I can't test if it fixes the bug (because I don't have it); I've only tested that it won't add any new one 😉.

UPDATE: official version 2.13.3 released, atttachment removed

Hi, I also have the same issue, I was about to report it but noticed that it already has been reported, well in my case it happens in hibernation (almost the same),

Anyways I've tried that beta version you attached and the problem disappeared

Here is a gif of the bug happening in the non beta version anyways, as you can see no sound (on the windows mixer) and the amount of voices is completely bugged:

Cheers
