<p>Well,</p>
<p>I never hear myself 'after I unkey' if using iaxrpt on a dahdi
node. Including on a Pi3<br>
</p>
<p>But using one of the radio nodes (with a radio) that use
simpleusb on the same server does create that effect.</p>
<p>Perhaps it is not a proper observation for compare since a direct
iax stream is not exactly the same handling/buffering.</p>

<p>Ed, ya know I have had the same issue and never had time
to fully investigate it. Was never a major issue for me,
just a annoyance.<br>
</p>
<p>It seems to vary in it's delay and I was looking for
other processes in memory slowing it down and found
nothing and always has plenty of cpu and ram.</p>
<p>Nodes with dahdi driver are never a issue on the same
server.<br>
</p>
<p>Could be some interference with cpu time-slice etc ?<br>
</p>
<p>But,</p>
<p>It seems to correspond to me when I did switch to
simpleusb this year so I would say try it with usbradio if
you have the additional headroom.<br>
</p>
<p>Perhaps I will switch back as well. It's worth noting and
trying.<br>

<div>Been running SimleUSB on my repeater for sometime.
All works well except for the variable audio delay,
sometimes will hear the end of my own transmission.
Know this issue has been around for awile. Someone
said try USBRadio, but would think that would use even
more processing and agrevate the situation.</div>
<div>This is running latest version of ASL on a

<div>Any input appreciated.</div>
