I just discovered that my 80D has no beep sound upon focus confirmation. I have set to enable beep already. I play a video clip and no audio playback despite I adjust the volume to highest level. Audio in movie setting was "auto" and not "disable".
I played the video on the PC by inserting the SD card and all was fine. There was sound recording.
I couldn't figure out the cause of the problem. One of the possible causes was the built-in speaker which may be broken.
Actually, I can live with it because I mostly disable beep and seldom playback video in the camera. BTW, there is a headphone port which I can make use of if I need.
I hope that wise people here can share their experience relating to sound problem on 80D.
When I am experiencing the above mentioned problem, I plugged in my headphone to the port to verify that nothing else went wrong. I face another problem. (This is the first time I ever use the headphone port.). I am not sure if the plug needs to be some sort of standard. When the plug was pushed to the inner-most position,there is no sound, I need to pull it back a bit to hear the beep and the video sound track.(It works) I then used a Sennheisser earphone and another Sanyo headphone to test it, they all behaved the same. I have to pull out a bit to make it work. Headphones have two rings and earphone has three rings.
I heard people saying that one needs to push the plug all the way in but I don't want to break something. Is there any particular headphone or adapter I need to buy to make it work perfectly. Please advise.
Happy New Year to all.
Update: I tried again plugging in the headphone more. It works. The headphone port has no problem.
I will contact Canon repair to ask the possible cause of the in camera speaker after the holiday.
I have reset everything to factory, removed the battery overnight and problem still persisted.
