In the sound settings of UDOObuntu appears "imx-vt1613-audio". When I configure it as speaker the microphone is set to dummy, and when I configure it as microphone the speaker is set to dummy. Volume settings: can either set sound card as input or output. Selected Line In as input, output switches to Dummy Output Vice versa. Speaker and microphone do work when they are set, but only one at a time. I'm using the newest version of UDOObuntu 2 on a UDOO Quad Kickstarter. Is this a bug in the OS or do I need to fix something inside of the driver? Thanks for your help! (original thread posted in wrong category)
Temp solved; used USB audio I/O device, that works just fine. Still searching for a solution with the built-in audio I/O though.
