Rowbi,

Thanks for your reply. I'm sure you'll appreciate I have tried every combination, sequence and chanted every mantra there is, but I thought I'd try yours again.

I loaded the latest version of Gearbox and the drivers for the XT and the KB37. No sound comes out my amp until I open Windows Control Panel, then double click line 6 Audio-midi control panel.

When this is double clicked the app I'm trying to use (Gearbox, Windows Media etc) works i.e. sound comes out my amp via the pod, and I can use the tuner etc with the guitar.

As soon as I change application the bloody thing stops making any noise until I double click the Line 6 Audio-midi control panel again. This is seriously wearing my faith in Line 6. I've spent quite a lot on their stuff over the years, but this is trying my patience too far.

I unplugged, uninstalled, restarted, and thee Line 6 Audio-midi control panel is still there.

Thing is, if I want to use and Line 6 software for recording, I'll still need this - and it doesn't work.

I have tried disabling the on board sound managers. No difference.

Anybody any ideas? Know any good witch doctors?

Hello there, thanks for replying.

I dusted off the computer again tonight (it languishes unloved in a dark corner), and had another look. The last time I used it there was nothing but the drivers for the pod XT and the KB37 loaded, and of course the AM control panel. The AM control panel, when opened, could not recognise any device. Hmmm. I downloaded the latest drivers V3.4.3.8 for the XT and the KB37.

Now with nothing else on the computer I had Cubase SX2, the drivers for the XT and KB37 (no monkey or any other line 6 software), no mouse or keyboard.

I connected the XT USB, windows found it - ready to use etc. I opened Media player and clicked on a track. The cursor moved but there was no sound. I opened Windows Control Panel, double clicked Line 6 AM panel and sound came out my amp. I stopped the track and clicked another. No sound, double click on Line 6 AM panel - sound again.

I disconnected the XT and connected the KB37 with headphones. Windows found it. I opened media player and repeated the above with the same result. The only difference being it was more of a hit and miss affair when I clicked the Line 6 AM panel - sometimes I got sound, sometimes I didn't.

Next I closed Media player, disconnected the KB37 and connected the XT and opened CubaseSX. I looked in the VST Multitrack box and both the XT and KB37 ASIO input/outputs were listed, I chose the XT, clicked Apply, opened a project. There was no sound until I opened Control panel etc. - you get the idea. I closed one project, opened another with the same results. In the XT sound configuration dialog box the ASIO client was listed as cubase.exe.

I closed Cubase, unplugged the XT, connected the KB37, opened Cubase, configured the ASIO for the KB37, opened a project and got no sound until I opened control panel and double clicked on the Line 6 AM panel, then I got sound. Again, when I opened a different project I had to repeat the procedure.

In the Line 6 programs folder there in an uninstaller which allows me to uninstall only the XT and KB37 drivers. Not the AM control panel. When I saw this earlier (a couple of weeks ago) I tried to uninstall Line 6 AM panel fro add/remove programs but there was no option. At this point I loaded the latest Gearbox in the hope it would get "picked up" then uninstalled, but to no avail - Gearbox uninstalled leaving the AM panel behind.

In the past I have had loaded Gearbox, Pod Farm, Vyzex Pocket Pod software and the drivers for the XT and the KB37 and Monkey. In all cases involving any program (Cubase, Reaper, Guitar Pro etc) I found I got no sound until I opened Monkey, so I thought Monkey was the problem, but now I have no Monkey, so to speak, but I still have the AM control panel which exhibits the same behaviour i.e. no sound unless it's double clicked. One thing I noticed is once when I double clicked the Line 6 AM panel it stated it may not have installed properly and 'Do I want to run it as if an earlier version of windows was running'.

The laptop is a Dell Studio 1557 with more than enough power to run and record (or so I thought). It is new and has only had what I have listed installed. I am running Windows Vista 64 bit SP2. I had previously run all my gear on a very low spec laptop running vista 32 bit with no problems.

I have tried rolling back to SP1 but the results were the same. I am waiting on a free upgrade to Windows 7 but I dont think that will resolve anything.

I have also previously tried uninstalling everything and defragging the drive then doing a clean install - many times. I have also tried switching the machine off then on again.

Sorry for going on but I reckon the more info you have the better chance you have of helping me.

Cheers
