Sound Quality in Video Conferencing: Troubleshooting tips??

[Tom Wagner <tw...@snarkboojum.com>]

OM 3.1.1 running nicely on Debian Jessie for all but one of my 
conferencing participants (logging in from mixed Apple and MS clients). 
   Of course he's the least tech-savvy and is located in the UK (server 
and most other participants are on the California coast).

His video display is fine and crisp in the Conference room, but his 
audio is muffled and extremely distorted--a sort of raspy rumble that is 
completely unintelligible.

  * His audio/video is fine in a Google Hangout
  * He is running Windows 10 on a Compac desktop.
  * He says his Flash plugin is up-to-date
  * No difference in audio logging in via both Firefox and IE.

Could his distance from the server be a factor for OM?  Anyone 
experienced or resolved similar issues, or have suggestions as to how to 
troubleshoot this particular scenario?

Thanks for any light you can shed....

Thanks, Maxim!  Just the starting point I needed.  Already had the user 
swap a wired external and his internal mic.  When I set up another  
'play date' with him to troubleshoot OM across the time zones this will 
save us both valuable time.

Best,

Hello Tom,

I would ask the user to use recording test: "Start recording test" button
on "Choose device" dealog
then you can modify config.xml and "play" with "microphoneRateBest",
"echoPath" and "echoSuppression" properties

this will require couple of round-trips:
1) you change the value
2) user will reload the page
3) test the sound
then goto 1 if it doesn't help

additionally I would ask user to try to use external microphone (for ex.
handsfree microphone from his/her cell-phone)
something like this
