Hi,
I’m troubleshooting a MacBook Pro 16" A2485 (820-02382, M1 Max) on macOS (Tahoe). Headphones work fine (3.5mm jack + Bluetooth), but internal speakers do not work at all.

When I try to play any system sound (e.g. afplay /System/Library/Sounds/Glass.aiff), it fails with:
AudioQueueStart failed ('what')

Logs from coreaudiod show the Built-In Speaker device trying to start and then failing immediately, e.g.:

Hi guys need some help on this Macbook

History of the fault :

There has been a some sort of power spike or short on one of those rails PP5V_G3S or PP5V_MAIN_ALSCAM_F . They are connected together via L8570 Inductor with was completely blown away from the board as well as small amount of trace.

I replaced the inductor and repair the track turned the MacBook on and noticed stray away it was warm . Camera still didn't work at this point so back with multimeter and found the LCD flex cable had a short . Replace with new one and the camera came back to live...

so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
