Guys, needs some input...I just finish re-cap the analog board and the logic board...everything work except the external speaker...so is not a capacitor on the analog board. I just order a TDA7052A to replace it. Any thing else that I need to verify! How can I test the speaker, maybe is that!

Ok team, I order a TDA7052A to replace it!
1. I took the speaker and plug it in to a 9v battery, the speaker is alive...
2. Took the analog board out and verify that the speaker cables where not damage. multimeter and continuity test - cable pass
3. re-solder speaker cables to the analog board
4. Put the TDA7052A in a socket waiting for the replacement
I put it back together and now speaker is working...maybe was a bad soldering point...but still going to replace the chip.
This maybe help someone else out there with the same issue.

I have a CC without sound on both the external speaker as the headphones socket. Logic and analog board is recapped, TDA7052A is replaced to no avail.
I don't have a 2nd machine to test with. I have checked for damaged traces from the headphones socket to the IC but couldn't find any.
