HI, I've got a 75-822 cb that has extremely low audio output from the speaker in both wx and cb mode.
It is barely audible until the volume is turned to at least 3/4 volume, you have to turn it to max volume to understand anything. the radio seems to transmit and receive fine (people can hear me, and I can hear them, thought the audio output is very low)

There is a small capacitor that drops value next to the audio output ic, usually heat sinked to the inner chassis, " ic should be checked" for hairline crack and performance, to answer your question it can be repaired.
Maybe you have it muted or a Tape Monitor engaged??? Never troubleshoot anything at high volume. If you can't hear it at medium it's effectively noth there. A flip of a misplaced switch would possibly blow your speakers.
Hi, my name is John. Welcome to FixYa. Turn your volume up to MAX, then turn your RF GAIN to MAX. If same, plug in a external speaker in back of radio into the external speaker jack. see what happens. If loud, re-place the speaker in the radio. Let me know how it goes, glad to help you and thanks for choosing FixYa....John
1. Yes, check to see if you have the volume up for the wave file turned up that is on the program you are using to listen to the Mp3 or sound wave with. 2. check the speaker connector/ Use another speaker that is know to be good and test. Use a set of earphone in the output jack also to test the output. If these things are doing the same then you have failing sound card and it needs replacement.
Open the audio panel (settings -> control panel -> Sounds and audio devices -> volume). Check that the volume slide is all the way to the right. Also, click on the "speaker volume" button and check it is all the way to the right
the conductor xxx\blk is the minus or black( from speaker) the outher is positive\red pin from speaker) the woofer is bigest speaker inside is connected on the crossover at low output, tweeter at high output, if you connect wrong you can burn speakers and crossover, you can test with very low volume on amplifier.
1st connect low to woofer, it only her low freq below 500Hz like drums and bass, if connect on med out the speaker is working as handpocket old radio audio. if connect on high the speaker is like no audio out. (the woofer take about 60-75% of amp power).
2nd connect the midrange at mid output you can listen to human voice cristal clear. if connect on high output you listem like esteric female shouting.
And connect the tweeter at the empty output
Take particular attention on polarity terminals, if you exchange the polarity you have a moofle sound traped inside of speaker, and some structered box noise who may open the box panels in future.
Initially, pls a couple of ideas you may want to consider/explore or try/check:
PA/CB switch must be to CB;
RF Gain max clockwise;
Squelch counter clockwise;
Volume to your desired level;
external speaker/speaker connection;
audio amp, verify if there is TX modulation;
antenna, antenna cable. SWR should be low.
Good luck and Thank you for using FixYa. Happy New Year.
