First timer on Forum. I have same problem on Dell XPS 1530 - laptop microphone unusable (picks up faintly because when I record/play back check I can barely hear sound.) Checked volume levels in Control Panel Sound -set to 80%. Video cam fine. Speakers work fine - checked playback with other sound bytes. All sound works fine with USB headset 0 both microphone & speakers. I'm trying to do Webex meetings, can hear others, but they can't hear me unless I enable the headset.
SPECS: Intel 2Duo Core T6400@2GHz; 4G RAM; 32 bit OS; NVIDIA GeForce 8400MGS; Windows 7 Ultimate 2009. Have check for latest updates on drivers. Don't know if it's an issue, but I have Skype installed and it is running as a process in Task Manger on auto start.
At my wits end. Hardware or software problem?
