Thanks for your help. In fact, I found that the cable needs to be in the port nearest the round port - it seems to be more "stable" there.
Here's what I did this morning:
Verified that all other soundcards and onboard sound are uninstalled. The Device Manager still shows Legacy Audio Drivers, but it's automatically installed with Windows and I haven't been able to find a way to take it off the system.
Completed uninstalled and reinstalled the MOTU drivers - the system kept "finding" new hardware and installing a second copy of the drivers. This seemed to fix that glitch, and all three were showing up in Device Manager.
When I started the mkII, it didn't get picked up by the computer and the bottom light on the mkII blinked continuously.
Rebooted the computer, restarted 2408. Now seen by computer and ins/outs show up in Console.
NO options at all in Sounds and Audio Devices under Playback or Recording (the entire thing is grayed out) or Voice.
(I remember that this window DID once show the PCI-324 as an option - no clue how or why.)
I re-enabled the onboard driver, but still nothing showing up under Playback or Recording.
YET: the PCI-324 showed up in Media Player. When I select "analog 1-2" under Media Player, then that option appears under Playback and Recording in the Sounds and Audio Devices. Media Player played the song (no error of unrecognized or missing soundcard) but nothing came out of the 2408 (checked headphone out, main out and analog 1 out and nothing from any of them).
Note: Under Volume tab of Sounds and Audio Devices, it shows "No Audio Device", even when the PCI-324 showed up in Playback and Recording.
I rebooted the computer. The 2408 was still connecting and showing up under Audio Console. Ran Media Player and got an error "No sound device..." and PCI-324 no longer shows up in Playback or Recording or in Media Player speaker properties.
I checked the Device Manager for the drivers and only the Audio Driver was showing up, so I reinstalled the other two drivers through Add New Hardware.
Now 2408 won't connect, even after numerous times turning it off and on, so I rebooted the computer. 2408 connected, but I now have TWO copies of the GSIF and Wave driver in Device Manager.
Under Media Player, PCI-324 no longer shows up.
I hit refresh in the Audio Console and the 2408 no longer connects and no ins/outs show up, even after numerous times turning it off and on.
I closed the Audio Console, disabled the 2nd version of GSIF and Wave driver (the first version stayed there and appeared ok).
Restarted Audio Console, restarted the 2408. Now connects and shows up under Ins/Outs of Console.
Still not showing up under Media Player and NOTHING shows in Playback or Recording in the Sounds and Audio Devices.
Forgot to mention that somewhere in there I disabled the on-board audio again, so only the MOTU is installed.
I then rebooted the PC, restarted the 2408 - took 3 restarts for it to connect and show up in Audio Console.
Checked Device Manager: only ONE copy of each driver, but Wave driver was disabled. I enabled it.
Now Media Player sees PCI-324 again and it shows up under Playback and Recording, but still No Audio Device in Volume tab of Sounds and Audio Properties.
Clicked Play on Media Player and system rebooted itself.
When up and running, I rechecked Device Manager. Now, TWO copies of Wave and GSIF drivers are present (again) and the one I enabled previously is still enabled but not working (exclamation point over icon). I disabled it again.
Ran the Audio Console, restarted 2408. It connected ok. I ran Media Player again. Now PCI-324 NOT showing up in Media Player, only "Default DirectSound Device" - though the onboard audio is disabled.
I ran Cuemix again the same as you originally said to, then restarted Media Player - no change.
Restarted 2408 - no connect.
Turned off Cuemix and closed it, restarted 2408 - no connect.
Checked Device Manager: only ONE copy of each driver present and (again) Wave driver disabled, so I enabled it, restarted the 2408, still no connect.
Closed and reopened Audio Console, restarted 2408 - connected.
Restarted Media Player - no PCI-324.
Checked Device Manager: all three drivers present and "working".
Wow, I'm truly baffled. I have a degree in computers and I'm used to playing with Windows to get it working right, and I like to think I'm pretty intelligent and good at problem solving. But this is just tying my brain into a giant Gordian Knot. It seemed to almost work, but no actual sound came out. Then it went back to being silly and has been residing in Silly-Ville ever since.
If I had to guess I'd say the computer doesn't like something about the drivers (or vice versa). My system is an AMD 3200+ 2.2 GHz with 1 GB RAM. Pretty sure it's VIA, but not sure which version - do you know how I find that out? The only codes I've been able to find on the chip is VT8370 (I think), if that helps. I'm running XP Home SP2. The drivers I have are the ones from the MOTU website, which says they're for XP. I tried the "32bit" Vista drivers (that are supposed to work with XP as well) and they locked the computer up nicely, so I went back to the ones I got from MOTU originally.
I even considered going back to my old slow computer, since it seems that the 324 doesn't like faster computers, but I need the speed to run Nuendo 2.0 well (which I already have) and the slower computer had a latency of about 350 ms.
Thanks again for your help in this matter. I only hope there's a way of making this thing work - and stably.
Oh, and by the way, I'm in Canada - clear around the planet from you. Dontcha just love modern communications?
