Audio Issues

[NW Marco]

I am using the BigBlue Button via Safari v17.4.1 on MacOS 12.7.4 and the audio sounds like the person talking is underwater. This happens via bluetooth or via the speakers. I don't get this 'bubbling' effect with any other online meeting software. 

Hardware: MacBook Pro 18,3 (M1 Pro chip, 16GB RAM). 

Appreciate any suggestions or tips to correct this. 

Thanks,
Marco in Seattle

I am also having a similar issue - I am using Chrome [Version 123.0.6312.107 (Official Build) (arm64)] and MacOS 14.4.1 on a MacBook Pro (2022, M2 chip).  The audio stutters and is very choppy while the video is very smooth.  Any ideas?

Hi Marco, 

Can you try with a wired headset , not Bluetooth ?

Thanks

Today's recording on my rig was completely fine.  I have no idea what differences there were.

I tried with the speakers on my laptop, got a bunch of feedback/static, then re-enabled the bluetooth and the audio worked fine. No issues. Hope this works next lecture (next Monday).

I tried the same set up as Monday - audio is very choppy and distorted, video is fine.  Help?  I cannot understand what is happening.  I have downloaded the video to YouTube: https://www.youtube.com/watch?v=fayVeQjtG2I   The sound is horrible.  How can I fix this?

Yet here is a recording from Tuesday...  https://www.youtube.com/watch?v=EDVKw2hMyis

does the choppy audio happen when users are listening during the live class...  Or only in the recording files?

[Joshua Sasmor]

Since this is a live face-to-face session being recorded, I usually have the audio turned down in the room to prevent feedback issues. I tested the audio before I started the recording, and the audio in the room was coming through fine.  I had one recording this morning work perfectly (https://youtu.be/dvySADLp51E ), and the second recording has choppy audio (https://youtu.be/CGxr0cEqv7c ).  I am using the Canvas API for BigBlueButton, recording using the microphone on my MacBook, and a desktop ELMO MO1 for the video.

Right before class started at 12:40 today, I started the meeting, joined the audio and turned up the volume so I could hear.  I heard myself correctly, with the barest lag through the speakers.  The recording has the choppy sound again :(    https://youtu.be/zffSZS6T4wg?si=PJvoC-tDea71GDdL

The problem is not fixed.  My 9am recording sounds fine, my 10am recording sounds fine, but my 12:30 recording is choppy as all heck.  I have no idea what I did different.

Are you running your own bbb server?  How many cores...   if recordings are processing from previous meetings and you don't have enough cpu,  you will notice audio quality issues once cpu exceeds 80

Hi Joshua,

Thanks for sharing more information directly.  The ping times between you and the server are quite large and are contributing to the audio issues you are experiencing.

Is it an option to try using a wireless hot-spot for a day of sessions and see if the audio suddenly improves?  That would further point to the network as a source of the audio issues.

Regards,.. Fred

I am not running my own server.  I am still experiencing these audio issues.  I do not control the Canvas API for BBB, so I cannot use that route to fix this.
