Then you should have set desired working rate at Project Settings (alt+enter), where is checkbox for setting of the rate and pull down menu with rate selection. Sample rate is usually automatically set at project level, that's with default option 'Allow projects to override device sample rate'. It should be unnecessary with ASIO drivers, it is automatically negotiated between Reaper and driver. Then after you confirm settings there, selected driver should be opened for use.Īlso I'd definitely uncheck two options there - request block size and request sample rate. It is because if you open audio device preferences, Reaper releases all audio drivers.

However your observation with ASIO not active is normal behavior, when you open this preference window. I already tried the card on another PC and this problem does not occur, it can work perfectly. I do not know if it helps, but the laptop is 64 bits, 4 GB RAM, Intel i3 processor, Windows 10 operating system (operating since 2014). Since it did not appear the 4.38 driver to remove, is it possible that there have been some files hanging around on my pc and causing this problem with the 4.59 driver installed? I rebooted again and the problem persisted. Only 4.59 was listed under '' In Programs and Features '', so I uninstalled that one, rebooted PC and reinstalled only driver 4.59 this time. After encountering this problem, I went to the 'Control Panel' and wanted to remove the drivers. At the beginning I installed the previous driver, 4.38, and then 4.59 (those that can be found on the official Behringer page).

So, I relate the problem of the recognition of the inputs with a non-activation of the ASIO, despite the fact that the most updated driver is installed and my card is recognized. '', in the '' Buffer Settings '' tab it appears as '' ASIO not active '' (see image 2). In '' Preferences '', it recognizes the 4.59 driver and lets me select it as the '' UMC ASIO Driver '' driver. The card is recognized by the pc, but the problem arises when I open the Reaper and I want to choose what input is considered to record on a new track (input 1 or 2) and it doesn't let me choose it (see image 1). I am having trouble getting my laptop to recognize the inputs on my Behringer UMC 204 HD card.
