Usb microphone records at an inaudible high pitch

Disco Dave · 2017-08-12 18:03:23

Hello all,

I am having an issue with my usb microphone. It is a Logitech USB Webcam and microphone.
When I record with the microphone the audio sounds extremely high pitched and inaudible. Here is an example https://ptpb.pw/l-Wc.wav. If I slow it down to 16000Hz in Audacity it’s more sane. This problem also doesn’t seem to happen when I don’t have pulseaudio started, so I’m certain the problem resides with pulseaudio.

I have tried following this recommendation, with no luck. https://wiki.archlinux.org/index.php/Pu … _recording

I’m pretty lost here, and am not sure how to go about fixing this. If anyone has any thoughts please let me know. I can also add any additional information if needed.

Thanks in advanced,
David
