PPSSPP and sound card power modes

[rockdarko]

Hi guys. I have a very odd question. I have a sound bar connected to my computer which goes in sleep mode after 15 minutes of non use, which drove me nuts since I broke the remote and cannot access the option menu to toggle that option. Turns out that when I have PPSSPP running with emulation PAUSED, I go around that problem. I'd like to understand what PPSSPP is doing to prevent my sound card from entering some power saving mode or whatever else you guys think it could be doing. Id like to understand to I can fix my problem without PPSSPP - although I'm reallly grateful for it!

I've tried other stuff unsuccessfully in the past such as playing a VLC video that had no sound but with volume on, etc and nothing worked, indicating that it may need an actual audio pulse to prevent sleep mode. But PPSSPP is not only silent but has the whole emulation paused. I'm really puzzled about how PPSSPP is interacting with my sound card to prevent it from letting the sound bar (connecte d via toslink) in sleep mode.

OS: Windows 10
PPSSPP: 1.5.4

Thanks so much in advance for any help. I realize as much this involves PPSSPP, this is not about using it.

Imagine PPSSPP pause as very start or end of mp3 with song - it will produce sound of a stright line aka silence, but it's still produced. When you run a video without soundtrack, it just doesn't have sound at all which isn't exactly same as silence.

If you're interested in trying some programming, it probably would be a nice app for someone new to C/C++ to write a little program that just sits in the background generating silence (except when the computer goes to sleep.)

On Android, it's important to consistently output audio for best latency. To keep things simple, we do that on all platforms. That's why we even output audio while paused.
