The instrument inputs on my Apogee Duet 1 are not working and the device isn't appearing in Maestro 2.

Question

The microphone inputs and the audio are working, but not always as they originally did. I consistently updated the drivers and have uninstalled and reinstalled the program several times. I had been having a similar issue with the microphone inputs and after a few reinstalls get them to work, but I'm not having any luck doing the same for the instruments inputs.

Answer 1

Hi Gen,
I'd be happy to elaborate and thanks so much for responding. The problem I had with the mic inputs in the past is similar to what's going on with the instrument inputs now. The mic inputs would work for a bit and then randomly stop. I'd go into the Apogee preferences in Logic and try to reset stuff, turn phantom power on and off, and play with the pre-amp levels which sometimes would work but often times not. The big difference between what happened with the mics and what's happening with the instrument inputs is that I could always get a read/level on the mics even though I couldn't hear them, but with the instrument inputs I'm getting nothing. Other than this, the mic inputs have worked as they should.
There have been two issues with the audio not working like it originally did. The main issue is that about 90% of the time I can control the output levels (whether in Logic, on the web, or in iTunes) using either the volume controls on my MacBook Pro or the dial on the Apogee. Occasionally, the Apogee will take over and I can only adjust the volume using the its dial. Normally, if I unplug and plug it back in this "fixes" it.
The other weird thing the audio is doing that just started happening and doesn't happen very often is that I'll go to watch something on YouTube, Vimeo, etc and the audio only comes out of the left channel. I'll mute the audio from my computer and/or using the Apogee's dial and I'll unplug and plug it back in, but normally I just have to deal until it fixes itself.
Here's a best guess timeline for when problems started showing up:
- The mic input issues have been on and off for about two and a half years.
- The audio output issue has been kind of off and on for a few years but became a more regular occurrence about     2 months ago and I believe it was after a reinstall that it started
- The left channel isolation started about a little more than month ago, probably around the same time as the audio
  output and probably has something to do with the reinstall
** I'm really unsure how long ago the instrument output problem started because I hadn't been using them for             quite some time. I think they were working correctly 7-8 months ago and I noticed the problem about 2-3 
    months back. I tried fiddling around with it for about a month before a reinstalled the drivers around 2 months
    ago
I hope that answers your questions adequately and I really hope you'll be able to help. Let me know if there is any more information you need. I should be much quicker to reply moving forward as I was away for most of last week and the beginning of this week.
Thank you,
Adam
