Hello, this is my first post and I've been having a problem with the built-in mic on my Lenovo Ideapad P580. The mic works fine for a while after I start the computer(vchats, voice recordings and such), but after a bit, it seems to suddenly stop working. When i check the status of the mic, both through mic selection on skype and on Recording Devices on the Sound options, the mic changes from "Internal Microphone" (which it was originally while it worked) to "External Microphone". At this point, it doesn't seem to pick up any sound whatsoever, confirmed through Skype and online mic tests, as well as the Sound Options. There does not seem to be a way to have the laptop recognize the built-in mic as "internal" once again, unless I reboot the computer. Only then is the mic listed as internal, but only until it recognizes it as external again, seemingly at random(one instance it took 8+ hours for the mic to be listed as external, another time it took less than 5 minutes since reboot). Unlike the problems most people have with mics not working properly(disabled mic, wrong mic selected), it seems like this issue is more unique; and since the mic is still functioning while it is listed as internal, I believe it to be a software issue. I was also wondering if drivers for the mic could be the issue, but I have never heard of built-in mics requiring installation of drivers to function properly. If anyone has any idea of the cause or a possible solution, it would be greatly appreciated . I wasn't exactly sure what information to post, since the specs of the laptop don't seem relevant to a mic issue, but if anyone needs more information, I will make additional posts later. Thank you!
