Hi
I'm still on holiday so can't try things!
Can you try an experiment?, in the ASIO panel, where the IO2 has got the red X's, there's a blue switch next to it
Try clicking on these just to see what they do,, I can't remember, but I have clicked on them?
Try them all! Try turning the realtec ones off, maybe that'll turn the others on?
This is bugging me, and frustrating coz I'm not @ my PC to try things!
Since I don't use the old sound card (Turtle Beech) I just disable in device manager or you can even disable it in the bios if it is causing you problems. Since I have not used ASIO4All, not sure if you are not turning something on. My understanding is ASIO4ALL simulates ASIO routing. So it takes WDM and uses it to create an ASIO session. So, you might have to do as jiff 41 stated and let the ASIO software know to route to the USB Interface. That could be why it is not showing up.
Not actually, I was suggesting disable the on board audio and use your card as a default sound card until you understand how to get it configured.
Just so we know, when you say "the monitors" do you mean the PC monitors or have you got some plugged into the IO2,
Because we are aiming for sound from the IO2, & the knob turned over to USB will give just the soundcard out/no direct monitoring!
But if you're listening to the PC monitors, it's different!
Another thought,, what can you hear when you plug phones in the IO2?,,,,,,& turning knobs?
Also, your monitors should be plugged into the interface. 1/4 in plugs from the interface output (Main L/R) on the backside of the the interface to the monitors (assuming powered monitors).
I hope we are helping.
OK, checking the basics:
Using guitar - make sure the switch on the front panel for that channel is slid down to the guitar setting.
Input switch - make sure the switch on the front panel is slid down to the analog setting.
Gain knob - try turning it up
Reaper options: inputs and output channels set correctly to the Alesis.
I'm old and a Reaper user too... about 5 years now. First, are you certain that there isn't an ASIO driver from Alesis for that interface? Best to not use ASIO4ALL unless you have to...
edit: I looked on the Alesis website. Seems there is no ASIO driver except the ASIO4ALL. So much for that thought...
I have and Alesis iO2 and I have not be able to make it work in windows 8. I tried all the ways but not was posible.
A Question:
Independently of the reaper´s problem. Did you get any sound across the Alesis IO2 from other program, for example, media player, or youtube, etc...??
Maybe could be a problem no relationship with reaper.
Hugs.
