<br>
I have to admit that I'm also a bit confused by this mail about
the asio (forAll) driver.<br>
How do I : " Choose the ASIOxxx driver as the
audio output device on the software"<br>

<p>Dear Bert, <o:p></o:p></p>
<p>The problem you have mentioned is perhaps due to the audio
buffer settings.
However, there are ways that one can use to get rid of this
problem.<o:p></o:p></p>
<p>1. Try to use ASIO drivers. <a moz-do-not-send="true"
href="http://www.asio4all.com">http://www.asio4all.com</a>.
Just download the the driver and install. Choose the ASIOxxx
driver as the
audio output device on the software. This will dramatically
reduce the audio
latency at the same buffer size as compared to WDM drivers. <o:p></o:p></p>
<p>2. In case the problem still persists try increasing the
audio buffer size
from the control panel of the asio driver. It will appear in
the bottom right
side next to the sound /volume control icon. Please note that
the ASIO icon
appears only when it is in use by a host program. <o:p></o:p></p>
<p style="margin-bottom:12.0pt">3. Best of luck. Do let me know
if you have any
doubts. <br>
<br>
<br>

Hi Bert,<br>
<br>
Since you mentioned a "windows code writer", and I am
one of them, I
thought I'd comment. The bottom line is that I don't
know what is
causing this problem. It does sound like it's latency
related in some
way. I thought Bill's question about the mouse was a
good one;
unfortunately, it's not clear that's the problem. I
recall seeing posts
in the past about how running a latency monitor resolved
some problem.Â
However, I don't believe it was this same problem.<br>
<br>
There is a different way that we can handle the software
threads in the
PowerSDR application to ask for better control of
priority from the operating
system. However, moving to that will require NOT
supporting XP any
longer. So, we're been waiting a little longer to go
that way. I
can't say whether that would help in this situation or
not.<br>
<br>
