That did give one more result: when plugging in the headphone-only jack, 0x18 (Not connected) reports present. I'm not sure if node 0x18 is actually related to the headphone for anything other than the jack sensing, though, as none of the settings for that node in hda_analyzer have any effect on the audio output on that jack (even the mute).
did you set pin ctl to OUT HP of node 0x18 ?
Setting OUT didn't seem to change anything. That node doesn't appear to support HP mode.
As I mentioned in the Bugzilla report, as it turns out, with default settings I can get audio to play out from the headphone jack with the "Analog Output" mode selected in PulseAudio. The big problem is that the audio is distorted with hiss and popping noises, which I haven't been able to figure out at all. Any suggestions?
do pulseaudio log show any path is removed since you don't have headphone playback volume or front playback volume , front playback switch?
Not sure quite what you mean. I've been doing most of my recent tests with PulseAudio not running, to eliminate that variable.
try hint jack_detect=0 to disable all jack detection of all jacks
and use hda-analyzer to mute /unmute the pin complex of line out and headphone
the other thing you can try is use hda-jack-retask to change internal speaker as [N/A] , this allow line out and headphone get it own volume control and audio output
I've tried all three of these now without any real success. Still that noise on the output. Think I might need to try some tests with Windows or other Linux versions to see if there is just some hardware problem on this machine.
