发帖数: 345 | 1 My window 7 pro system has been running for 2+ years. Couple of weeks ago I
got message of "mic hardwire muted" message from Google hangout and it
stopped working suddenly. I tried suggestions from the net and nothing
worked so far. Situation summary:
1. tested the mic( stand alone with 3.5mm plug) on other machine and it
works.
2. device manager shows the mic is default and says the device is working
properly. input volume is set at 100%, boost at 20 db. There is no "mute"
option shown though.
3. have reinstalled the device driver ( high definition audio device), only
one shown in device manager. Also tried update device driver and it says the
current driver is up to date.
4. "sound recording" program does not register any audio input. |
