Problem with Mac Lion audio driver #292

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Log on to Wonderland with a Mac running OSX 10.7 or higher
2. Talk to other people for 10-30 minutes

What is the expected output? What do you see instead?

The audio starts out fine, but a fairly regular intervals starts to crackle and 
quickly becomes so bad that it is impossible to understand other people when 
they speak.

The Wonderland native code that talks to the Mac audio drivers probably needs 
to be updated.

Troubleshooting advice from Joe Provino:

Try recording the audio the softphone is receiving: Show the softphone, click 
Call, select Record.
In the record dialog enter a file name.  Select Audio for now.  Click Record 
Speaker.
Everything written to the speaker (what you hear) will also be written to the 
file.

After you hear the problem, click stop and try to play the file to see how it 
sounds.

Also try bringing up the perf data by clicking Call, select Perf Monitor,
then select all six graphs.  The should all be nice straight lines.

This should give you quite a bit of information.

Another thing to try later will be to tell the bridge to record the audio its 
sending to you.

telnet <vb ip address> 6666
ci (this will list all calls.  find your call id)

recordToMember=true:<callID>:<file name>:Au

after you hear problems,

recordToMember=fals:<callID>

The file will be on the bridge server (I think) but you may be able to specify 
an NFS path.

Also instead of "Au" you can capture the "Rtp".

On the bridge side, you can monitor performance similar to what the softphone 
does.

cd jvoicebridge/branches/jp/bridgemonitor
ant run

This also could be a USB audio driver problem. And it happens on multiple 
versions of Mac OS, not just Lion.

Needs more testing.
