You may have one of three problems: Your audio accessory jack is bad, you are using the wrong mic for the radio, or your mic is bad. Try the mic on a known good BPR40 and if it test good, if so, your BPR40 with the problem needs a new audio accessory jack. (Repair is available for this model.) We have found the BPR40 will only work properly with the remote speaker mic designed for it, despite some other Motorola mics appearing to fit the jack. Construction grade mic PMMN4013 is a good option, as is the lightweight PMMN4077.
Can you see the s-mete if it has one moving up and down on any channel? Do you hear any audio at all? could be a couple of things. Bad mic switch or mic cable, bad antenna or coax, bad audio amp. To check the audio amp plug in a speaker to the PA jack, put the PA switch on PA then press the mic to talk. If it works the audio is fine the mic is good and the mic cable is good. Noiw plug the speaker into the speaker jack, do you hear anything? If not then your antenna or coax has a problem, fix or replace antenna or coax.
No, it has no built-in Microphone, you'll need external microphone to record voice or do audio calls/chats, etc.. Hope this helps.
Let me know if you need further help.
Good Luck.
Thanks for using FixYa.
First, try your mic on a different PC. If it works, then come back to this one.
This model of Compaq PC has always had a little trouble with speakers and audio in general. Try inserting the MIC's jack into the output, and see whether that works. Generally, don't go by their color coding, just plug it into a jack until you find the one that does work.
Make sure that you do not have the MIC turned off, either in the audio controls' software, or the physical MIC. You should be successful.
In most cases the front jacks are in addition to the rear ones. It's not an either/or situation. If the speakers are connected to the rear jacks (usually green for speakers and pink for mic) and there is no sound, you might have a problem with the onboard sound. Try connecting to the rear jacks with a good set of speakers and try it out. If this doesn't work then we can go from there.
You need an amplifier between Laptop/PC jack to drive the high power speakers/subwoofers. Or buy the special system like Logitech's Speaker system (speakers-subwoofer) that has a built in amplifier already designed for PCs/Laptops. Radio shack has amplifiers of various inputs and power levels.
