Greetings, I have acer 4315 laptop with realtek alc268 codec. (It also has hda modem which I don't use.) Looking at the datasheet, the codec has 2 PCM outs, but alsa hda driver with model=acer shows only one. I want to know if I can enable the 2nd output, and use the external mic jack as a second line out? I can see that PCM2/LOUT2 connects to HP-OUT (widget 0x15), while PCM1/LOUT1 connects to several pins 0x[14,15,16,18,1A] How do I go about testing this. Does the hda model=test enable *every* widget and PCM and allow change of pin direction etc? BTW I want to use the 2nd output as the secondar "preview" (prelisten?) headphone output for my audio player (pytone), while main output is going to speakers.
