Hi All,
Trying my hand at snd quirking, I'm working a Dell Latitude E4310. Here's what I'm seeing. There's a headset jack (HP/MIC combo) on the LHS, when I insert a headset I see the following in the logs.
Note: port 0xA is the mic jack, 0xB is hp jack, and 0x11 in internal mic.

I've tested against kernels 2.6.32 and 2.6.35rc2 with the same results. The mux is indeed back where it started after the plug is fully inserted.
Node 0x17 [Audio Selector] wcaps 0x300d0d: Stereo Amp-Out R/L Amp-Out caps: ofs=0x00, nsteps=0x0f, stepsize=0x05, mute=1 Amp-Out vals: [0x0f 0x0f] Power: setting=D0, actual=D0 Connection: 7 0x0c 0x0e 0x0f 0x1b 0x11* 0x12 0x0a
and I can push it around with hda-verb to get the desired result... The question is why is it doing this? To make things weirder, I can get input from the external mic even if it isn't selected. This is my first attempt at making codecs "do the right thing" so I could very well be missing something obvious. What else am I missing here? Thanks.
