Hello Leif and list users:
Thank you for fast reply.

I will answer between you text lines:



If it worked before, it should still work. If it does not, the reason
is probably something that could and should be fixed.

Yes, that is what I think!..:-)


Maybe the soundboard_init.log file has some information?
(I do no longer remember when this file was introduced, but it should be
present in recent Linrad versions)

Here is sounboard_init.log information:

No. It indicates I made a mistake somewhere;)

In 01.03 you have a choice:
Use close and reopen for D/A when
a new signal is selected (Y/N)

Choosing yes or not does not make any effect.

A first question:
When you run 01.03 and have clicked on a signal. Does it
happen that it runs OK until you click on a new signal
or does it always stop with sync errors after a little while?
The answer on this question might give a fast route to the source of the problem. It will be very time consuming
on a 486 to find out between which two versions the change
that makes your 486 computer not run was made.

Stopping the output while the input is left running does not
work always and I have made various things to make errors
less frequent. I think one device stops the interrupt response for the other one during a too long time. Maybe some of the
things I did to handle those problems was bad for a RDWR device.
With the parameters I have sent to you the problem is the following:

I click with the mouse and I count seconds, with the following result:

Time(secs) result

0 I click the mouse
11 output starts
16 output stops
29 output starts
33 output stops
45 output starts
50 putput stops

You can see that it follows a fixed pattern, sound starts after 11 seconds, last 5 seconds and goes off for another 11 seconds. Perhaps this data will help you.
