Detects internal speaker in System Preferences but no sound
No boot sound and no sound when in OS (10.14.3). System Preferences shows that the internal speaker is there. I can plug in headphones and the output source changes to headphones and sound does play through them. I've replaced the speaker, I/O Board, and cable that connects I/O Board to logic board. I've tried resetting SMC and PRAM. I've booted to a live Linux USB and sound doesn't work there either. I've run out of ideas besides replacing Logic board and/or CPU riser board. Thanks for the help.
