Graham,

the buffers of ASIO4ALL and corresponding in PSDR are 1024 wide because otherwise I have problems when I start other programs or surf in the internet. I have to make clear: The shown panadapter-image of the received signals IS OK! You can see the whole 48kHz and the tuned station immediatley - but you cant hear it!

The size of the .png HAS nothing to do with the problem because the size of the original "default" picDisplay.png is 2,56 kB and the original "IK3VIC cyan" is 16,8 kB (400x200). My selfmade picDisplay.png with callsign has 4,86 kB and 600x300. From this pixel-numbers (!) on the problem rises. The more pixel the oftener it happens. It is the amount of pixels not the size of file.

@Ray J: thats a good point to check. I did not do that up to now. I will try and report.

Could someone try on his own Vista-32-System and check if thats right what I say? Perhaps it only exists on MY System and I have to do research on my environment or on my damaged brain ;-)

Create an image 1600 x 800 pixel (e.g. with paint.net that I use) and save it as "picDisplay.png". Accept the suggested conditions paint.net gives (it will not be much bigger than 15 kB than) and store it e.g. to the default skin folder (c:\users\/yourename/\AppData\Roaming\FlexRadio Systems\PowerSDR\Skins\default\Console). The effect should be that after release of ptt you see the panadapter working ok but you cant hear anything for more than 10 seconds.

I share my created image if you like.

And again: I do not expect you to do work on this! It does not affect the normal usage of the program. But I think if something like this strange happens there could be much more strange effects within the developement environment.

Martin:

This delay in starting audio stream is a symptom that you have set the buffer sizes too small on ASIO4ALL. Try increasing both the size of the ASIO4ALL Offline controlled buffers to 256, and the Startup/Audio buffers to 512 or 1024 and see if the problem improves. Then you
can experiment with reducing the buffer sizes again.

Please note that the buffers inside of ASIO4ALL do not change until you close PowerSDR and restart. You may have to power cycle the FLEX-1500, to drop the USB stream, also,
to allow the buffer size change.

So, I am guessing that the change in the size of the ".png" file has nothing to do with the
delay in the audio stream restarting.

But you can never be sure with software.  :-)

More likely, you changed the size of the ASIO4ALL buffers, didn't see a change, so left them small. Then, when you restarted everything after working on the display, the smaller
buffers took effect, and the problems began.

If you want to improve the operation, we see that Windows 7 has much improved audio drivers, relative to XP or Vista. At this time, best operation will be achieved with Windows 7, using the Windows WASAPI driver. Long term we will have a new FLEX-Radio USB driver
that will work with all operating systems, but this is not ready yet.

     Shure. You can“t start audio without the program is completely
    loaded and display is stable...
    If you let it stay for a few minutes and than start audio (again)
    it happens as described. Try it.
    Btw: OS is Vista 32.

    You do not need to give this high priority but I wanted to inform
    you because if such strange things happen there might be more
    strange behavior at all.

          Shure, but if that is 2,8 kByte or 4.2 kByte does not realy
        matter for that.
        And what has that to do with sound delay????
        There is a function between no. of pixel in relation to
        seconds of sound missing.

        Not realy important  but somewhat strange...

            I believe the images are intentionally small to make load

                Hi,

                shame on me! I decided to change the background picture
                (picDisplay.png) on the default-skin.
                I wanted my callsign to be displayed in right up corner.

                So I edited the picDisplay.png (100x50 pixel) and
                wrote my callsign
                in it. I wrote it back and because the background is
                being zoomed up
                to about 1400x700 pixel the letters became very muddy...

                So I did a new picture with about 600x300 pixel and
                this was
                displayed much smoother and nicer.
                And now my problems begann...

                If I pushed the ptt and than released it the
                panadapter showed up the
                received sigs again but sometimes no sound came from
                the speakers!
                After a few seconds (5 to 10) sound came back.

                I then changed the picDisplay.png to a new picture
                with 1600x800
                pixel and then reproduceable every time no sound after
                ptt-release
                ever since...
                Changed back to 100x50 pixel and every thing works
                great again.
