Subject: Re: [App_rpt-users] Distorted audio in app_rpt/Allstar

I have nothing but problems with an amd processor that I was using as my first node.  A lot of it was audio related as well.  I can't remember if it was Steve or Jim that ask me the very same question.  I ended up trying an intel CPU on a pretty Low end machine and all my problems went away.  I have built many nodes since for both myself and others and have never had that problem show up again.

Huh? Now you see me stumped. I can see some badly designed math library having a problem with that, but what does that have to do with the processor. I am not discounting the statement, just trying to gather information, and the statement does not just come through the filter I have in my brain as to makes sense.

As far as the CPU goes, yes I do have an AMD chip:

Any chance you are using an AMD processor?  If you tx tone and your voice are more than 999 combined, that could also be the problem.

Best I can describe the effect is that the audio is time sliced in 20ms packets and every other packet is missing, left out. and it does not happen when audio is especially loud or quiet. Sometimes it happens on the time announcements, which are absolutely perfect 99% of the time.

Sounds to me like a computer with too little RAM or too little CPU horsepower.

When you run the top command, is it using swap memory?  If so, that's bad...and you need more RAM.
