Part of the connectivity is: Line-2 pins are output, and connect to both the internal speakers on the laptop, and a headphone jack. If I configure NID 0x1b as output, and NID 0x13 to select the "front" input source, then program mixer NID 0x0c correctly, and send data to DAC 0x02, then I hear audio on the speakers (or headphones) just fine. Alsamixer correctly controls the volume. However, there are also 3 audio jacks on the back of the system - namely, front, surround and center/lfe. These are allegedly connected to the front, surround and center/lfe pins on the ALC880 (the side-surround pins are unused). Now, I know DAC 0x02 and mixer 0x0c are working fine, since they affect the internal speakers when routed through 0x13/0x1b. However, if I program pin NID 0x14 (front out) just like I programmed pin NID 0x1b (line2), then I can't get anything to come out. As an experiment, I tried every possible programming of pin NID 0x14, and nothing works! The same experiment using DAC 0x03/0x04 and associated output pins doesn't work either. I've sat running speakertest, plugging both headphones and regular PC speakers into all the audio jacks, and no luck. (I've also tested all the other DACs and mixers by routing them out the line2 output, so I know the problem only lies with the other output pin configuration, or beyond somewhere on the PCB) Any ideas of anything else I might try to debug this?
