Mic Problems with CWHS, IBM A21m

[jumpingpound]

I recently set up CWHS on my laptop to do some recording on the road. Everything went fine for the first week or so. But now, whenever I record, I cannot get my IBM laptop A21m to listen to the mic-jack or line in. The computer 'listens' to its own internal mic exclusively, and ignores the other imputs. Essentially, I cannot record a thing due to this problem. I cannot recall changing any settings that would have caused this to happen.

This problem actually is not a CWHS problem. I've tried adjusting the properties in the volume dialog box, as well as the soundcard settings on the control panel, with no effect (the card is a soundfusion audio). I've checked the leads and all other equipment on my home computer, so I'm very certain that the problem is on the laptop.

Any advice would be much appreciated.

Greets Mr 'Pound,

So once it worked, and now it doesn't. How very computer-like is that???

Does the Soundfusion audiocard have its own software mixer? You may want to check that nothing is disabled there.

Also, bear in mind that anytime to tweak HS2002 you really ought to run Options/Audio/Wave Profiler. This has frequently been the culprit in problems such as you are experiencing.

Good luck!

Thanks BluesMeister.

I finally discovered that a stepdown from one of my guitar leads had blown. For some reason this caused the internal mic in my computer to activate, because the it could tell that I was trying to record but couldn't sense anything through the jack anymore.

Thanks for the advice though. I do re-run the wave profiler fairly often when something is amiss.

One other question: When I play into HS2002 and input monitoring is on, there is a delay of a fraction of a second from what I play to when I hear it through the headphones. Needless to say, this really screws up timing. Is there any way to correct this?

You need to reduce your latency. You can try moving the slider bar in Options > Audio to the left, and/or lowering the number of buffers being used (assuming it is set at something higher than 2). However, be forewarned that you may start getting dropouts at the lower setting.

Also, if you don't have WDM drivers for your sound card, see if you can locate them. However, if you are using the computer's built-in sound card, it is likely that won't be able to get a latency setting low enough to remove the echo.

(Course you can always turn off Input Monitoring as another solution.)
