Broadcasting audio using latest Google Chrome (version 23) on a mac has poor audio quality #1357

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Google just updated Chrome to release 23 and we immediately noticed that when a 
user is broadcasting audio from their Mac, that user's audio will sound robotic 
to others.   The test setup is

  Chrome 23.0.1271.64 (mac)
  Flash version: 11.5.31.2
  Mac OS 10.8.2 (32-bit)

We're pretty sure its a bug in Chrome + Flash.  We tested Chrome 22 on a mac 
and broadcasting audio sounded fine.  Upgraded to Chrome 23, and the 
broadcasted audio sounds robotic.

What does work:
On Windows, Chrome 23 works great -- a user's broadcasted audio is clear.  On 
Mac, Safari and Firefox on Mac is fine as well.

Workaround:
If (a) you are on a Mac and (b) need to broadcast audio in a BigBlueButton 
session, we recommend using FireFox or Safari browser, not Google Chrome.

The broadcasting audio problem seems limited to Chrome running on Mac.  Others 
are reporting similar issues as well with shaky audio

We're digging further on this ... hopefully Google will release an update 
shortly.

Following the thread on the Chromium Bug Tracker, it looks like the reported 
bug has been merged into this issue

   http://code.google.com/p/chromium/issues/detail?id=157613

Not surprisingly, many others are encountering this issue.  For the moment, 
recommend that Mac OS X users use FireFox or Safari with BigBlueButton until 
Google releases Chrome 24.

Looks like they have the fix in the next build of Chrome (Chrome 24)

Marked as WontFix -- nothing to do at our end as this was a Flash bug in google 
Chrome.
