Joe,
Since you put in a new chip and no audio.. could mean a short at the speaker jack or speaker.
If you turn up the volume does the current go up? does the chip get warm ?
Did you have any audio earlier before the smoke ?

Greetings,
I finally got my uBitx assembled and in the case of it's final destination.. I checked my wiring on everything, and nervously applied power.. Display came up and I was happy.. turned the VFO for a sec and watched the frequency changed.. pushed in to change function.. all at once.. I smelled the magic smoke smell and the audio chip went pop... I happened to look in my parts bins and I have happened to have a few more.. it appears from a different manufacture, and these are the "M" flavor. I replaced the audio chip.. but I have no audio, via headphone or speaker.. I turned it off.. wanted to check with the group..
