I just recently had this Thunderbolt and it doesn't recognize my voice when I use my bluetooth headset. It is weird because the voice recognition software works perfectly without the headset.

I thought it was just a sound quality issue or too much noise in the background at first. So I went to a more quiet place and tested it but it acted the same. Using a headset is very important for me because I always work outside.

Anyone here had the same problem? Feel free to post here your suggestions and tips. Thank you so much. I appreciate it. 

I was installing new windows and reformat my computer.  And now, I can’t hear any sound on my speaker. I’m not really sure what's happening during the installation with my windows XP. Do I need to reinstall again the windows XP?
