Hi Thank you for all your help.
i Downloaded the Zoom L-20 Driver as zoom said,
The problem i had was is getting the 22 channels to show on the cakewalk program, so after reading online people have used the Asio4all driver i downloaded it and then got all the channels showing on the Cakewalk software.
I just tried this morning playing back the recording that was popping and cracking but using the Wasapi instead of the Asio4all driver, i plugging the headphones direct into the computer and there was no audio playback problem at all. So the issue is Wasapi wont show the L-20 channels on the cakewalk software.
Also When reverting the driver back to Asio4all cakewalk bought up a message saying that the driver may not be compatible with cakewalk do you want to use Wasapi.
Is there a Asio driver that may work properly ,Im think the problem is the Asio4all . Thank you
