Hi, Audio in this camera is handled by usb-audio driver not uvcvideo (video only). In any case when grabbing audio from it make sure you set the sample rate to 16 Khz (mono), a sound server like pulse should convert the sample rate and channels automatically, but if you are not using it then you must use the correct frequency.
Regards, Paulo in your test you are using 8 khz: > Recording WAVE 'test' : Signed 16 bit Little Endian, Rate 8000 Hz, Mono 2010/10/4 EJS <ejsh...@yahoo.com>: > Hi all, > > So I went out and bought this web cam because supposedly it worked right out > of > the box and it did.
