XTL5k no audio out

I have an XTL5k and can not figure out why I have no audio out of the main speaker. Tx is good and Rx is good. Took this radio out of a HMMWV after a power issue. After fixing the power issue I relized I can Rx but no audio. I put a multimeter on PINs 20 and 26 on J2 rear accessory jack (where the ingnition sence wire and SPKR-/+ hook in to, saw voltage vatiations when Rx'ing. Anyone else ever had similar problems. Swaped cables, swaped speeker, no dice.

Thanks
Hatch

No, no audio on the bench. I get voltage variations out of J2 PINs 20 and 26 (spkr +/-), but it isn't driving my speaker/s.

Looked at it with a scope rather than a voltmeter? I suspect the audio ic died.

No scope and my comm system analyzer is in for repair. I didn't know if this was a simple problem that can be resolved. If not, RMA time. Thanks for the help!!
