All too often, I have a problem with stuttering inbound audio. It’s happening every few minutes and it lasts for several seconds then clears up. I don’t know how to describe it other than it sounds like the voice is mixed with about a 5 Hz signal. Has anyone experienced this type of problem, and if so, have you solved it?

This is a hard one to decipher because it can be so many things. Your system, your local network, the Internet, and the same things at the other end. There are a lot of people with poor signals, either audio level or quality or packet loss on both Allstar and IRLP and of course echolink.
Does this happen on all stations? Does it depend on local network loading? Do you here it on an echo test? What kind of Internet connection do you have? Do other report problems on your signal?

Well I don’t have enough experience to say you are wrong but I can say there are plenty of people that don’t have the problem. If you think your computer does not have enough horsepower to run usbradio then try simpleusb. It works fine. I have been running Asterisk as a PBX for over 10 years and there are some applications and some things you can do to make audio go sour but “fundamentally” the system is sound and used by hundreds of thousands worldwide.
So what is the “fundamental” bug in the software?

There is nothing wrong with his system. This is a fundamental bug in the software. I have heard this now described in many different ways, but I am certain it is the same problem again and again. Since we have all different setup, networks, … It is very unlikely that every time it is a problem with the ‘customers’ site. We just have to admit and acknowledge that this is a bug in the software and we will face this until the software is being fixed.
There seem to be a number of things we can do to alleviate the problem but it’s not going away.

I have several of these systems and have used the usb fob and the voter board/RTCM’s. I run the systems on Intel ATOM motherboards and have had no problems due to the systems or the software. But I have had problems caused by network components. One time I had what I can describe as stuttering audio and I one by one tried rebooting devices including all devices of the all star system, the network switches, and the network router. I did these one by one and allowed time between each and the device that fixed the problem was one of the MikroTik router boards. After rebooting it the problem was solved. 6 months later the problem came back. This time I only rebooted the MikroTik router board and it fixed the problem.
Don’t blame the allstarlink system or the app_rpt or the centos system as they are proven to work reliably for very long periods of time. cheep network switches and routers are the most likely cause of problems, and even the expensive network switches and routers have been known to cause these problems.
Also, if you are having problems with the Asterisk system crashing then first look at the hardware that it is ruining on. I play with just about every feature that the system has and even try making it do thing that it is not suppose to do and try pushing it to it’s limits and it is very solid.

For the system that has the telemetry announcements issue, please provide details of your configuration and setup, are you using usb fob or uri or RTCM? Are you using DSP or simple? What CPU and what Speed? What motherboard? Any USB hubs? What OS install, which version of app_rpt? if using RTCM, what version of code on it? how many receivers? What other software are you running on the same OS install? Did you use the allstarlink.org web interface and let it install the config files or did you hand create your configuration files? Are you using virtual machine? Are you using ntpd? What configuration options are you using (send config files). The more information that you provide, the more likely someone can identify exactly what will fix the problem. Without any of that information, my first guess is that you are using a slow single core CPU and maybe you are running ntpd with a usb fob on a hub and DSP enabled. Is that what you have? Please give details.

In my line of work (software engineering) we call a problem that comes up again and again and again one of two things: either a bug or fundamentally bad software design. Since this problem happens only once in a while I tend to believe its a bug rather than fundamentally bad design.
Now as for all the network mumbo jumbo: if you have the same problem of garbled audio on telemetry announcements (which my node does) then all hardware outside of the PC is irrelevant. If at the same time the PC shows a utilization of only about 10% it is fair to assume there is enough horse power.
The faster the developers accept we have a real bug here instead of looking for the source everywhere else but in the code the faster this bug will get resolved.

Not sure where it is from precisely. I found it to not be the asterisk stuff, though. It only was a problem when I was/am having issues with U-Verse. When stuff that is normally 70ms away is more like 800ms away this problem can occur.
When my network connection works fine this does not pop up. And this is very different from the USBRADIO recurring audio “gaps”, like 10ms gaps in groups of maybe 8 that recurs every 10 seconds or so. That one I’m sure is how the OS deals with the USB audio device.
