Question / Help Video Source Plugin keeps lowering obs volume level in windows volume mixer

[fieryludus]

This issue has been going on now for around 5 days now; Every single time I preview my stream or start streaming my obs in volume mixer is set to a very low volume level. Everytime I put the volume up after an hour or so it lowers back down to the previous value and I have no idea why. I have gone to sound settings > Communications > and set it to do nothing, around 5 months now it has been at that setting and I have had no issue with obs until recently. Is there anything anyone can do to help me? Thanks for a response ahead of time.

OBS doesn't interact with/change the Windows volume mixer levels, so this must be caused by something else.

Hmm I thought so. The weird thing though is I haven't actually installed anything new on my windows installation so I don't know why my windows 8 is doing this specifically to obs and nothing else. Is there anything you would suggest that I could possibly do to try and fix this problem?

I found out the exact reason as to why it's happening. Seems to only happen when the video plugin loads a scene.

I'm going to try and reinstall the plugin soon and let any other people who might have the same problem know if I've fixed it that way.

Maybe your plugin interferes with the Windows volume controll.
There is an option to lower the volume of certain programs, when windows dectects comunication.

Just right click on the speaker icon and select sounds, then go to comunication and set it to "Do nothing"

I hope this helps ;)

For sure my plugin is interfering with my volume control somehow, I had that option set to do nothing this entire time and yet it still is happening. I'm not 100% sure if it's related to the plugin or maybe it's the fact that gigabyte told me my audio drivers were available on windows 8 when they really weren't. Probably the second one, I'm almost 100% sure it's the fact that I don't actually have a sound card with drivers installed; it's just audio through amd which is very limited.

EDIT

I have found the reason why this happens but the problem is only half solved and keeps setting my obs volume to 50% instead of 15%. If you go into the video source plugin scene and change the volume to 100% it won't attenuate or lower your volume as much but the problem is still there to the point where I still have to raise obs through volume mixer every time. Anyone have any thoughts on this and how I might go about making it not lower it to 50% at all?

EDIT2

Reinstalling video source plugin for 32 bit and 64 bit obs does nothing to fix the issue.

So if anyone else is still having this issue, I found that what caused it for me was that the volume bar in my capture card scene in OBS controlled the volume mixer in windows. I recently changed some audio settings and didn't realize that that was the cause. Hope this helps anyone else who stumbles across this problem.

I'm having this problem! Has anyone found a solution?

Since this thread has been bumped for an answer I want to provide the answer to an old problem that people still seem to be having. Hopefully this helps people in the future who have the problem so here's the fix:

Hope this helps someone else out; turns out it had to do with DirectX audio output being selected instead of WaveOut audio output.

This is actually a Windows feature gone horribly wrong, like sticky keys, nobody likes those. Right click your sound mixer, and go to playback devices, (or Sound from the control panel) same place.
Click the "Communications" tab.
Normally, when windows detects communication activity, usually for some kind of phone service, it reduces all sounds by 50%. It seems to see OBS-MP as one of these applications, reducing all sound.
Simply set this to "Do Nothing" and problem solved!
