I’m currently having trouble with all versions of Audacity, including 2.x.
When I attempt to record microphone input by pressing the record button, Audacity receives the input and begins processing the audio data. However, if I press the stop button or if the recording goes longer than ten seconds or so, all recorded data is erased and the track becomes a flat line (silence). Audacity is unable to generate tones as well. If I try to generate a chirp for ten seconds, a ten second track is created, but it is completely silent (this assures me it is not a microphone problem). I assumed the files for audacity were corrupted, so I uninstalled/reinstalled twice, being careful to delete all contents from the C:/Program Files/Audacity folder manually after each uninstall. I have played around with different settings on the input/output hotbar within Audacity to no avail.
I am suspicious that my audio card’s drivers are corrupted. I recently uninstalled a trial version of MorphVox Pro and the associated Screaming Bee Audio Driver that simulates a soundcard in Windows. The problem seems to have begun right after that uninstall.
Anybody have suggestions? Need more details?
