Sound cutting when using obs

Hi all.
I use OBS to stream to twitch but am having an issue that after searching i cannot find an answer to.
I stream iRacing through a Rift S and use the built in mic/headphones.

Playing is fine however as soon as i open OBS it starts to cause the sound to cut in/out and crackle. A split second or 4/5 seconds at a time .

When streaming i have open :
Iracing.
Crew Chief app.
Race labs Overlay.
Discord.
Obs.

Even if i run without Discord the sound issue continues.

I did try changing in sound settings the tick box that allowed 1 prog to take control. Made no difference.

It all worked fine previously but was quite some time ago i last streamed and have been updates to all programs since.
I did increase the bitrate as the stream was stuttery and dropped a lot of frames on the first attempt, however lowered the output to 720p to help this.

Any suggestions appreciated
