Re: bc72xlt-no audio/sound/ kids pressing buttons then no...
The best I can tell you is try readjusting the volume and squelch again. Turn your volume up then adjust the squelch all the way one way and then all the way the other way. At one of the max settings you should get static noise. This should allow you to see if there is any noise coming out of the scanner.
If you get noise then recheck to see that the scanner is programmed correctly. If it has no frequencies or frequencies with no traffic on them, you will not hear them.
If there was no audio with the squelch then you may want to consider that there is a bigger problem. Page 53 in your manual describes how to reset your scanner. This might work as a last ditch effort. You will lose all of your current programming though.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

It's very simple even if you don't have the owners manual.
Step 1: Hold in the Menu button until "DEMO" shows on the display screen.
Step 2: Scroll with the volume knob until it says clock. Then press the volume knob to select it.
Step 3: Scroll with the volume knob until it says "CLOCK SET." Then press the volume knob again.
Step 4: Then adjust the hour first by scrolling with the volume knob. Once the correct hours shows press the volume knob and it will move on to the minutes.
Step 5: Once the hour and minute is chosen push the menu button again to finish the procedure.
I suspect you have it in the continuous monitor mode so follow the directions for getting back into the automatic squelch mode.
AUTOMATIC SQUELCH: The FRS is equipped with an automatic squelch circuitry filtering out weak transmission and unwanted noise, usually caused by terrain conditions.
MONITOR: - This feature turns off the automatic squelch feature, either momentarily or continuously. It helps in receiving signals to its maximum range, but may pick up static signals, too.
Momentary monitor: - Press the MON button; the monitor symbol will appear. - Release the button to restore the automatic squelch.
Continuous monitor: - Press the MON button for more than 2 seconds until a beep sound is heard. The monitor symbol will appear. - To restore the automatic squelch, press and release the MON button again.
NOTE: You cannot transmit when the Monitor feature is activated.
Your BC72XLT SCAN feature samples one frequency/channel at a time, but it should only stop on active frequencies. If it's stopping on inactive frequencies you may need to adjust the squelch.

In your manual, if you have one, if not look it up on the internet. There are ways with all these types of communications, to reset to manufacturer and factory settings at time of new purchase. Then proceed forward in programming.
You are right there is no adjustment. You can however turn the squelch off and this maybe what is happening to you.
To turn the squelch off you press and hold the button that is just below the push-to-talk button for at least 5 seconds.
To turn the squelch back on, you either press (less than 5 sec.) and the same button or change channels.
When talking with a specific party or group, you should use the tone coded squelch (CTCSS) and that will mitigate the noise if you are not already doing that.
Press and hold the volume knob to get into the setup menu. Press and release the knob repeatedly until you see "Clock Adj". Push the DISP button, then turn the volume knob to adjust the hours. Push DISP again then turn the knob to adjust minutes. When you're done, press the volume knob again.
