-=SOMETIMES chimes. Usually doesn't. I'm mostly sure both speakers were hooked up but only the Left side (LIO side) sounded when it did chime=-

It does not seem to detect the headphones. System Information has no entry under audio device.

PP1V5_S0SW_AUDIO_HDA - 1.5
PP5V_S3_U6210 - 5V (what a legacy name)
SPKRAMP_SHDN_L - 0

I traced SPRKAMP_SHDN_L from U6210 to the LIO’s “sub-J9500”, it connects. Not being sent by LIO codec chip?

I'm on my 4th LIO, 3rd flat cable. They all look fine under the scope but i never trust these.

– more info –
  • This is another shop’s. Tech said he opened it up to look, but didn’t touch anything.
  • they claim they did a PRAM reset and audio came back for a week. Now PRAM reset no worky. I'll definitely play around here more, that would be dumb if I missed this
  • I've probed out J9500, all pins seem solid, and in diode mode no pins have any unexpected readings.
  • I have not probed from J9500 down all the HDA lanes
  • I’d usually have had this one fixed by now so it’s personal
