Are you using the simpleusb channel driver? It's unclear, but you
do mention something about COS in one of your replies below.
Using the simpleusb channel driver drastically cuts down on the
number of processes necessary, where usbradio uses much more CPU.
HOWEVER, if you are using usbradio (what we call full DSP) then
I'd like to know more about your set-up. If you are using
simpleusb, there's no argument, and that explains it.<br>
<br>
Please let us know.<br>

I’ll have to
disagree with
your
statements
completely. I
have not only
personally
load-tested
but I have and
know of many
high traffic
systems that
are running
with zero
“sputter” or
issue.l on a
Pi. Several
have been on
the air and
running for
well over a
year.<br>
<br>
I am also
running one
system in
conjunction
with DMRLink
and
transcoding
audio (read a
much heavier
demand on
System
resources)
from
DMR<->
Analog with no
“sputter”.
Granted the
transcoding is
offloaded to a
separate chip
but
nonetheless.
On all of
these systems
running on a
Pi 2 or 3 the
system load
from asterisk,
DMRLink etc
all combined
never exceeds
15% and the
audio is
always clean (
not
withstanding
network
craziness ).<br>
<br>
So having said
all of this I
would look
elsewhere for
what may be
causing your
audio
ailments. I
can’t really
point you in a
specific
direction
other than to
review overall
system load
and
performance
inline with
general system
administration
best
practices.
And of course
standard
troubleshooting
methods of
hardware
swapping/testing
and
validation.<br>
