Distorted audio - no explanation

Hello,

  I have an interesting situation. I have been using Allstar for

over a month discovering its capabilities. Tonite a friend on
node 28679 tells me my audio is distorted. Im puzzled because I
haven’t changed any settings on my node in a few days, although I
did setup a new server that will go next week to Puerto Rico.

  So I turn on a remoterig radio in Chicago (independent of Allstar)

to listen to myself, and indeed my audio sounds awful. So I check
for all possible causes, but nothing changes. I switched radios,
power supplies, moved cables around, but problem continues. I even
reset my network and changed switch. Yet I decided to use echolink
to connect to same exact hardware/URI FOB etc, and audio sounds
perfect. I thought it was my friends radio, but I connected his
radio to the WINS network during a net, and audio was fine.

  So my question is this. My 2 nodes on same server can connect to

each other (28532 -> 28689), audio sounds great. I connect to
node in Chicago, and audio is awful. I use echolink with same
exact hardware on both ends, audio is perfect. So it is not a
hardware or audio setting problem. It seems to be network and/or
related to VOIP audio. I have yet to test with someone else other
then KP4EOP.

  I even tested with the new server I am setting up, and it also has

same issues. Even changed ports. Anyone seen this happen?

have you set your audio levels to the standard app_rpt/Allstar TLP?

Yes, audio levels are set perfectly. Believe me, I am totally perplexed as to what is causing this as it just happened out of nowhere.

I can connect from one node to another and audio sound great both ways. It's only when I connect outside my network using Allstar.
If I use echolink from the one node that has it configured, to the node in Chicago I'm testing with, audio sounds great. Same hardware.

It is not an audio level setting problem. It is not a usbradio option setting, as I use 2 entirely different radios and both have same situation.
It is not a server setting, as I have tested on 2 separate servers, and same problem.
I rebooted both servers several times. No change.

The only common thing is my network and ISP. Tested with my IRLP node, all is ok. Tested bandwidth, everything looks good (average 40MBPS up/ 5MBPS down).

Well, maybe we should get together, bring up a connection, and swap some tone.

Please (off list, of course), send me your phone number and login info to your
system (so that I can see it from both ends while we are testing).

Time-wise today things are not looking good. It’s definitely a majorly serious skater day.
My friend and I are going to Westchester and also check out the old (rather bowly)
park at Venice.

So if I get back soon enough (keeping in mind the time difference there) I will call.
However, realistically, we went to bed at about 0200 our time last night (er, this morning
I guess).

I am almost 98% sure my problem is related to the IAX jitterbuffer feature

The reason I say this is because it happened suddenly, and it was occurring on 2 separate servers within the same network. Also the Remoterig device that allows me to remote control/use a radio uses SIP and has similar features as Allstar/Asterisk that I adjust based on bandwidth.

Now I need to understand why this has changed and how to solve it. My Allstar node(s) are currently unusable because I sound with lots of packet loss. But I can hear everyone well, and the echolink connection via Allstar sounds fine.

My system began having some latency issues (that you could see by monitoring jitterbuffer) when I connected a F.O. media converter elsewhere on the same LAN. The problems went away when I replaced the device with another one. Apparently the first device was flakey and interfered with local internode comms in some way…

Did you make any changes to your LAN or could some other device on it have failed?

Does rebooting the computer fix it? We get an under water sound from time to time on our older computers. Rebooting fixes it.
