Title says it .
I rebooted windows 10 several times.
It worked with the old 2023
Others have that problem ?

Try this;
Make sure your ASIO interface is turned on before before starting RB.
Make sure nothing else is using that ASIO device.

I have not heard of anyone else having this issue specifically with 2024.
Have you made sure the ASIO driver selection in Preferences - AUDIO tab - ASIO Driver area is set to the desired device?
IE, make sure RB is not trying to use a different ASIO driver than expected.

Thanks Rharv
I have done all you suggest.
Ill test again to be sure.
Was the old RB 32 bits?
I wonder if there is a thing there.
I use an asio from l6 gearbox.

OK .It was my line6 guitar port/ Gearbox that needed a renewal via USB port.
The ASIO belonged to that program
