Re: IC-7000 no rx and no sound out from speaker

Good work James. Did you see anything on the display like a reaction on the S meter. Won't be surprised if not as some of the clocking inputs to the codec chip come from the clocking I/O pins of the ADSP chip along with the chip select for the codec IC551.
Well you've proven the audio path from AOUT +/-, now to get a digital codec signal out of SDTO and back into SDTI.

Confirmed the audio circuit from IC551 to speaker is ok by injecting 1khz tone at various points after IC551.
Now waiting for the replacement ic551 to arrive.
will keep you updated
