Okay, I tried everything you said. As a last resort, I plugged in an external USB Microphone from the Nintendo Wii, which btw does not show op in arecord -L, but doesn't matter anymore. When plugging in the EXT microphone via USB, the internal microphone just works. More testing will follow. What situations should I test to make it easy for you guys to figure out a conclusion? And what could be a solution? R On 11/13/2013 11:14 PM, Bill Unruh wrote: > On Wed, 13 Nov 2013, Ruben De Smet wrote: > >> I tried on Ubuntu 13.10, doesn't work either.
