LV won't has no sound input

I am using LV 2010 sp1 10.0.1 32 bit on a window XP system.  It has been running for over a year when it appeared the 3rd party sound card went bad.  We replaced the card but it didn't fix the problem.  I can record sound via window record function so I know my input is good and the card is working but LV gives me a low signal failure. 

 

Any suggestions?

Do you have proper error handling in your application?

Can you post the code to the application?

 

What i think is that you have hardcoded the name or ID of the device into your application and the new sound device does not match this. Hence you will get errors but due to incomplete error handling, the user is not notified about this issue....

 

hope this helps,

Norbert

Thanks for the reply.  I am not at all sure what you mean.  I think we are using the standard LV program with nothing special.  So I really don't know what it is you are asking me for.  This system has worked for over a year, I thought the sound card went bad and replaced it with an identical card.  I now think the card had not failed but some file was corrupted and now I have a problem.  Tell me what file you would like to see and I can post it.

Thanks for your help,

John

John,

 

you have to identify the hardware somewhere in the application. If the application uses the LV Sound functions, you will need to select the "device ID" as shown:

I assume that this ID is not correct for the new sound device. So it will not work!

Thanks, found the problem, it was the micsens.txt file.  I deleted it and it took off running. Supposedly it will recreate it if the file is not found. This file tells the LV where to set the low level threshold for input.
