I recently went from Windows XP to Windows 7. I am running Audacity 2.0.5 loaded with the .exe installer. With XP I had no problem with Audacity recognizing and recording from my Shure PG27 USB Microphone. Now it doesn’t recognize the microphone.
Can Windows see the mic? As far as I can tell it uses the Windows supplied drivers, so it shouldn’t require any special drivers. If Windows can find the mic, Audacity should see it too.
Windows sees the mike but it is flagged with a yellow triangle indicating a need for “troubleshooting”. When that’s selected it shows up as "Shure driver not installed. I’ve looked for an appropriate driver and can’t seem to find it.
That mic is Plug and Play so there are no special drivers.
I assume you see the yellow triangle in Windows Device Manager. I suggest you right-click over the entry that is flagged and choose “Uninstall”. Then remove the mic, wait a few moments, reconnect the mic, completely shut down the computer, wait a few moments then restart the computer.
If the problem persists, try another USB cable.
And do start Audacity after you settle up with Windows. Koz
