Asio4All- wouldn't that possibly be the ticket to fixing this?

 
Possibly, but check if Bose has ASIO drivers first, or updated WDM drivers.
Another thing that affects recording is hardware acceleration.
From SONAR 6 help files:
 
There may be a conflict with your video card or other multimedia streaming card Some video drivers contain bugs which can interfere with SONAR's operation. Or, the driver may be "stealing" excessive CPU time away from SONAR (some video card vendors, in an attempt to make their cards operate faster, supply drivers that tie up the computer's bus for relatively long intervals (so-called "PCI bus contention"). This can interrupt the smooth flow of audio data between SONAR and the sound card's driver.)
Try to remove the video card conflict as follows:

Try turning off "hardware acceleration" on your video card (if available). This may cause more sluggish screen drawing, but may improve the flow of audio data to your sound card, thereby reducing the possibility of dropouts.

To disable the hardware acceleration on your graphics card: Launch Control panel (Start-Settings-Control panel). Double-click the Display icon. Select the Settings tab. Click on the Advanced Properties button. Select the Performance tab. Move the slider for hardware acceleration one notch at a time toward `none' and re-test your recording/playback after each such adjustment. If problem(s) persist, leave the slider at `none' and proceed with the next step.

will try this. I didn't see that BOSE had any drivers there.
Also, it doesn't seem to be JUST with the BOSE but any kind of audio recording. I'll keep monkeying...

First, I agree with what greg has posted.

2nd - this is confusing me.  what "other audio recording" are you talking about?  with what "other" soundcard are you recording?

well, there were the issues I was having with MC5 and my Maudio card on my desktop.
Also the Line6 Toneport (on the laptop again) that was also troublesome.

Sorry, I know it's a lot to ask, but I just want to be able to open a program, hit RECORD and be able to record more than 5 minutes in any given environment. Sounds like the laptop that I have is (of course) not optimal for doing what I want to do, so maybe I'll just get a cassette recorder that can do the job. ;)

I don't like it when stuff is harder than it should be and when I miss getting good recordings because of software issues. Drives me nuts, you may not've noticed though! :)

so are you saying you want to be able to record using the line6 OR the Bose system at any time?  that might be difficult, but you can probably pull it off.  you HAVE to use WDM driver mode for that, but you'll need to manually switch which soundcard is set up for the INPUT and OUTPUT DRIVERS as well as the RECORDING and PLAYBACK TIMING MASTERS each time you switch from one soundcard to the other.

Wait Beagle- the Asio thing is not the way to go? Setting up the output and input is totally understandable.  However, Playback Timing Master has me confused. Where is that located? I don't have my laptop with me

well, you can use ASIO as well if you still change your soundcard drivers manually.  I didn't think about it like that.  both ways, however, you need to change the drivers and the timing masters.

the timing masters are on the first tab of the window that pops up for OPTIONS>AUDIO in MC5.  the drivers are on the same time, IIRC for MC5, but on the last tab for MC4 and below.

Okay, so I tried Asio4all. It seemed to record a lot longer than before, however, when I played it back, it was all garbled. 

I messed around with the setup and tried it again WITH THE SAME settings and it worked fine.
??

you could have some background program causing problems, then.  antivirus, webcam, tv card, wireless network - anything that runs while the computer is on might cause that intermittent problem, but those I mentioned there are the "usual suspects"

yeah, I looked through those in my task manager and thought I had shut everything down. Strange that it'd be all screwed up and then just kind of 'fix itself'.  I remember similar issues with MC3 too.
Anyway, I was able to record last night straight for about an hour, so that was cool. I probably could've done more, but I stopped after an hour. Cool. Hopefully, the next time I go to use it, it will work as it did here.
