Sound setting keep changing!

[Gunsmokingman]

If I leave it on default sound in OBS, I do not record any sound at all! I have to manually switch it to the correct sound source in OBS! This has been an on going problem for a while now. When I select the sound source at some point it switches back to default were you get no sound recorded at all! it would be nice if there was a fax for this problem!

I guess you speak of the audio settings in Settings > Audio > Global audio devices.

If there is some devices set to "default", OBS is substituting the current default Windows device and keeps this device until you terminate OBS. If the default Windows device changes, for example if you plug in a headset and Windows switches to the headset as default, or you plug out a headset and Windows switches to the previous default device, OBS is not following this. OBS keeps the device it got at startup.

Another thing to notice is the behavior of Bluetooth headsets, if you happen to use one. Usually, they provide a high quality device suitable for music output. If you activate the mic of a bluetooth headset, the headset switches to voip mode and this usually means the headset is switching its output to a different lower quality voip output device. The high quality device becomes silent.
To avoid this switch, remove any reference to the mic in OBS. For example, if one Mic/Auxiliary Audio setting is set to "default", this refers to a headset if switched on, and activates voip mode for the headset. Set this to "disabled" to avoid the switch. Or if you require the mic, explcitly configure both headset playback devices as desktop audio device - one is always silent and the other is always working, depending on the activation status of the mic.

Sorry for my bad post.
1:\ When I set it to my TV as the source for sound, it will at some point in time switch the setting back to default device.

Just to be clear. Your TV is NOT the source for sound.
On your computer, you have specified to output Default Windows Audio through your TV.
In OBS, you are selecting the Audio Output device (the TV) to be the Default Global (Desktop) Audio 'output device to monitor'

just be careful. the TV output is not a Source. The Audio channel being output via the TV is the Source.
Unfortunately, sometimes the semantics are important.

In this case, I'm guessing a HDMI connection/display, right?
The issue is that when the Operating System first starts, the TV is probably asleep, or driver initialization delay, or something. But, I'm guessing, for a bit the OS Default Audio output is NOT the TV monitor. Right? some initial BIOS startup beeps, etc do NOT come from the TV, right?
if my guess is correct, that Operating System Behavior is what is impacting OBS Studio (device enumeration, etc).
Personally, I don't use Global Desktop Audio at all (I've disabled it in OBS Studio), so I don't have any advice on fixing your issue. but, in Sources, clicking on the Device adjusting which physical interface/device to associate with is quick/easy (and would annoy me to have to do every time)

I'm wondering if you have a different Audio Output device you could select which wouldn't have this issue? First, I'd go into Sound System properties at OS level and disable any Audio device not in use. Then it depends on audio driver/hardware as to what your options might be

Thanks for the information.
The problem is the setting at some point changes back to default device in the sound properties, when that happens, no sound is recorded.

Hi Gunsmkongman,
I am also experiencing this! Did you work out how to prevent this?
Or why it happens?
