I have an Aspire M5-583p laptop that I just upgraded to Windows 10 and installed the new drivers recommended from Acer. I found that I had an issue with the microphones were not found by the sound input on my device manager and called support online. The tech named Suresh for the out of warranty contractor remote in and after only pinging an IP address of 127.0.0.0 (this will always fail) told me that I have a corrupt windows DLL file and if I purchase a support ticket (ranging from $99.00 to $299.00) that he would be able to resolve the issue. I said that if it was a Windows DLL issue that I was going to call Windows support and he said that Windows support would only be transferring me back to their support site. When I asked to have him send me a copy of our transcript he closed our conversation out and dropped the link. After that I went ahead and re-downloaded the Realtek Audio Drivers and resolved my issue (in which Suresh vehemently said that the driver was not the issue).
