Wanna record multiple URLs from websites at same time in OBS

[joejim]

As always, I searched this forum (and Google) first but did not find any answers, so here I am.

I get URLs(ESPN, HBO, CNN, etc,,) from Firefox then record in OBS under Source/Browser/URL. One URL records perfect, video and sound.
I am not sure if this is the way to record multiple URLs??, but I launched second OBS and entered second URL, Plays fine in OBS.
Now when I record second URL from second OBS, video is fine but sound gets mixed with first recording ( I can hear double sound).
Actually when I record both URLs at same time, videos are fine but sounds are mixed on both recordings.
For some reason I am not separating or isolating the sound.

First question is this. Is launching second OBS way to record multiple URLs? or better way?
Second, how can I avoid mixing sounds when I record Multiple URLs?
I think answer is obvious and simple under my nose but I just can not find it.

Just now I tried recording two URLs from two OBS (separately launched),
Both videos and sounds are perfect, no sound mixing like earlier today.
I do not know what I did different just now? Closed both OBS then opened again and entered URLs.

But still like to hear any comments?

I think(?) I found the answer.
Before I start, I noticed even website sound (cus I was watching websites while OBS was recording) was mixing with URL recordings.
I found Control/Settings/Audio/Devices, Desktop Audios were set to my PC sound (Realtek), Maybe this is why sound recordings were mixed??

Anyway, I changed Control/Settings/Audio/Devices, chnaged to "Disable" on both Desktop Audios.
Now I can watch and hear websites while multiple URLs are recorded in OBS. Resulting recordings do not have mixed sound anymore.

Was this the right answer? or did I get lucky ?

Yes

Hey, I tried this. But even with just one window, disabling the Desktop Audio makes OBS not record any audio for that browser for me. Does someone know how that can be solved ?
