Alto Live 2404 usb audio codac not seen in Reaper audio setup options window with Windows Vista 2 Home Premium OS

My Alto Live 2404 mixer can play music from my Windows Vista Media Player but the Alto Audio Codac isn't showing up in Reaper's DAW Audio Setup Options window? Its an older version of Reaper (4 years old). Any one else had this problem/solution with Reaper going through Windows Vista 2 Home Pro w/Reaper DAW? Thanks...

  • Solution Found: REAPER DAW has a "ASIO Configuration" drop down window in it's Audio Device section under Options. When you click it open, your i.e. "ASIO4all Driver" configuration window will open and it is here that you will see your Alto Live Mixer "USB Audio Codec". Just click it on so you see a + next to "USB Audio Codec" and turn any other sound card to a - next to there icons. Now you can record in Reaper from the mixer. I'm getting a high freq whine from my headphones that doesn't make it to the rendered recording but it's a distraction so I'll try and solve that next. Cool..

  • Hi Jesse,

    I'm glad you were able to get your initial inquiry resolved!

    Now, as for the high frequency sound you're experiencing in your headphones, if you wiggle your headphones around or bend the wire in any way, do you notice a difference? Do you hear any noise from your main outputs at all? Is your mixer connected through a surge protector? Make sure your outlet is not being overloaded, as well, as this can introduce noise into your signal flow.

  • Hi Bill, thanks for the reply. I have an electronics background and this is the trouble shooting I performed. I powered the mixer from a isolated transformer with no cables connected to the mixer but the USB and the headphones, all connections tested stable. Two different lap tops were run on battery using Reaper DAW and WMP with the exact same results using different usb cables (Vista and Windows 8.1). This is not a a bad connection or a ground loop. The mixer can play music from WMP just fine with no high freq whine but any type of host that is using ASIO4all (Reaper and VSThost) will have the high freq whine whether in play mode or record mode. I can run the same lap tops through a Bheringer UCA 202 usb analog to digital interface into my 4 channel mixer using Reaper and VSThost with no problems. I understand this is not the most common of problems, but it does surface from time to time with USB Mixers from different company's. This is just a lemon mixer with a USB malfunction. Since this was a "right out of the box malfunction", Quality Control Testing should have caught it? I'm returning the mixer to Alto for a replacement and hopefully this third time around will fix the problems. I love Alto gear and especially the Alto Live 2404 Mixer, wonderful engineering and design. Sincerely...Jesse Pearson
