I have surfed, swam and jetskied my way across the web trying to find a solution to this bloody mic problem. I bought the a150 (linpus version) and installed XP succesfuly following a really good guide on youtube. I then looked for drivers from acer's site and downloaded everything for windows, including the CCD folders while not knowing what they're for. I installed them all together, instructing NOT to restart until all drivers have been installed. - now, my sister had bought the same exact model a few days before i did and knowing of this mic problem, just before i was ready to restart for the changes to kick in i tested the sound.. it worked.. i tried recording with the mic.. and IT WORKED! .. i restarted.. and it didnt! :cry: after hunting for a fix online and trying all different audio driver versions my long forgotten troubleshooting skills kicked in.. IF at one point it worked, then a restart was it's undoing then the problem MUST be from one of the other drivers installed.. in particular one of the drivers which required a restart before it kicks in... i haven't tried this out yet, but hopefuly anyone out there might try to play about with not installing some drivers.. I think the CCD are unneeded.. and are probably the cause of this problem.. esp since the apparent issue with asking u to plug in the webcam when it's built in (and even "uninstalling" the device through device manager and refreshing didn't help it see the webcam) ended up with u having to terminate it's install in order to restart i'm dying to try this out..
