microphone not working properly in my Acer Aspire 5720

It will record with the right settings, but it sounds choppy and you can barely hear it. I have tested it with 'pavumeter --record' and through the sound test in Skype. I have to turn the internal mic boost all the way up in 'alsamixer -c n' and then turm the volume all the way up on my machine to hear the playback, and then you barely hear it.
