Hi All, I've got an Udoo Quad with a fresh install of the latest OS, UDOObuntu_quad_v1.0. I'm trying to play back and record sound sound but there is no signal comming from the speaker output. All alsamixer channels are up and the Pulse Audio Volume control setting looks right. i can see the signal in the Volume control monitor from ALSA plug-in [xmms2d]:ALSA Playback... but now sound from speakers. Any advice is greatly appreciated.
