Solved Problem with Webex meeting

Status
Not open for further replies.
Hi everyone,

First of all, I apologise if I have by any chance started my thread in the wrong part of the forum. I put it here because the issue is related to a laptop and could possibly be either a hardware or a software issue (not sure). I also apologise for the lengthy message.

I have had the following situation. At work, we had a Webex meeting and I used my Windows 10 laptop. Another coworker (let's call her Coworker A) and I were in the same office, whereas the other participants were in other locations. Before the meeting began, we had a deal that Coworker A would not use earphones, whereas I should use them so that we can avoid echo because we are in the same room (not sure about the correct technical term, I am referring to the situation when the sound basically gets multiplied). Therefore, before the meeting I plugged in my earphones and checked to make sure they were firmly plugged in. Coworker A and I tested my microphone together (Webex users know that you have this test at the beginning, where you speak a few words that get recorded and then played back to you - everything went fine, and I heard the recorded words through my earphones, just like I should).

The meeting started well, several other coworkers spoke, and there were no problems. Then came Coworker A's turn (again, no problem). After finishing her part, Coworker A didn't mute her microphone. I started speaking after her and the echo started immediately. When Coworker A muted her microphone, the echo stopped right away and I continued normally. After me, several others spoke, including Coworker A again, and there were no issues.

After the meeting, Coworker A insisted that I must have done something wrong to cause the echo. She suggested that perhaps I accidentally unplugged my earphones, which I am 100% sure did not happen. From the beginning to the very end of the meeting, I heard everything that was said only through my earphones. Also, I did not touch them the entire time. So, that explanation is not valid. She also suggested that maybe I needed, after plugging in my earphones, to press on the little speaker icon in the taskbar and, if I understood correctly, there should be some settings there. However, even though I didn't do it before this meeting, we tested my microphone before the meeting and everything was fine, i.e. no echo at all.

Now, since I can expect more Webex meetings in the future, I would like to make sure this never happens again. So, I would appreciate any ideas regarding what I could have done to cause this (or what I did not do but should have done). What confuses and concerns me most is how the test went fine, and then during the meeting the echo appeared even though I did not touch anything. So, something must have changed during the meeting. Are there some hidden settings I should know about?

Also, do you guys know how I could possibly prove that I did in fact have my earphones plugged in the entire time? Is there a log in Windows 10 (I suppose not, but I am asking just in case)? Also, if it doesn't, then in the future, is there a way for me to somehow ensure I can prove when my earphones were plugged in without installing new software (not allowed under company policy)?

Again, sorry for such a long post.

All best
 
Sorry I have no specific suggestions as I don’t use that software.
My thought is that Coworker A’s microphone was picking up the sound from her speakers which would give a type of feedback echo. Are you using the headset’s microphone or the PC’s microphone? If a headset then it’s possible her headset’s plug wasn’t fully inserted.
 
I agree with Bastet

Echo is caused by mike picking up on speakers. If your headset was not plugged in properly you would not hear anything.
They do not work half plugged in.

No
 
To add to what has been stated have been seeing more portable system with all in one mic and speaker connections.

If the coworker was using a standard head set then that also may explain the issue since the pins do not align correctly.
 
Thank you so much for your help. Just to clarify some circumstances: my coworker was not using anything - no headset and no earphones. She just used her laptop with built in speakers and microphone.

I used just the ordinary earphones that contain no microphone, the same ones that I use to listen to music on my phone. As for the microphone, I used the one that is built into my laptop (i.e. no additional microphone plugged in). Before, when I said I heard everything only through earphones, I was referring to my laptop only, and I meant to say I did not hear anything through my speakers (i.e. the sound was coming out of my laptop through earphones only). And since my coworker was using just her laptop with no additional devices, I also heard everything through her speakers. Sorry if I caused confusion.

I am sure my earphones were plugged in completely as I heard the entire meeting through them, including everything that was said after I spoke, and I didn't touch them the entire time.

Was explained to you in post # 3
