I have a Dell Inspiron 1521 Laptop with Vista (OS). We have tried everything we can see to do, but have not had success. Under Recordings, the Line In Mic shows one bar of sound, but In don't think it's doing anything. The computer isn't detecting my voice when I try speach recognition. I heard the Vista had issues with the mic, but it there a way to turn it on, LineIn or Onboard?
I was working with bhanshew in chat trying to resolve this issue, I am going to summarise the troubleshooting steps we took,
1) we went into properties and confirmed that all settings were set up correctly
2) we tried attaching an external microphone to ensure internal wasn't broken
3) we ensured the microphone was not muted, we also tried muting the microphone (after reading from various sources that muting the microphone fixed the problem.
We checked all sound controller and it said it was working, after trying everything I could think of I GOT bhanshew to post here, I hope you will be able to resolve the issueGood EVENING bhanshew and welcome to CH

When you where trying different fixes are you sure that the mic PLUG is in the mic port and the same for the speakers etc? or are you using only the built in mic and speakers?

In the device manager is there any red or yellow items, if not look up top for the view then click on hidden DEVICES is any of them show any issues etc.

Hope to hear from you soon, Mike
