Radio works, but no sound after jump start?
2004 LS430 CL, wife's car.
I decided to charge my new Garmin unit from her car instead of mine because her battery is less than a year old. I left the ignition swith turned to accessory and plugged up a battery tender over night while the Garmin charged.
Next morning, battery was dead anyway and my wife was in a hurry to leave. I swapped the battery tender for a standard battery charger and moved the switch to 10 amp, waited a minute, and it wasn't quiiiiiiite charged enough, wife kept on and on so I switched it up to "Start"/50 amp and it fired right up. Now, the radio functions (changes channels, switches to CD, CD plays-the disc shows that it is playing,etc) but there is no sound, same goes for the beeping sound that comes from moving the temp of the climate control up/down, no more beeping.
Car is totally stock, stereo is stock Mark Levinson.
Any ideas?
TIA

Blown fuse on the amp?

I checked all of them (4) that the owner's manual noted as Audio related. 2 in the front pass kick panel, and 2 in driver's side trunk. All were mini fuses and all were good.
If I'm on the Audio screen on the dash and I press the sound button, it moves to the sound screen, but it won't let me press anything = none of the adj are highlighted.
