Sound Problem version 2.0

Hello again,

My attempt at using sound has come to an abrupt halt.

I have the following script:

sndCmd.cmd = sndCmdFreqDurationAmp;
sndCmd.param1 = 1500;
sndCmd.param2 = 400;
sndCmd.param3 = sndMaxAmp;
SndDoCmd(NULL, &sndCmd, true);
                                    
sndCmd.cmd = sndCmdFreqDurationAmp;
sndCmd.param1 = 1200;
sndCmd.param2 = 400;
sndCmd.param3 = sndMaxAmp;
SndDoCmd(NULL, &sndCmd, true);

I am just trying to make a simple chime similar to a door chime. This works perfectly well in POSE, I get DingDong as expected but on an m505 I get DongDing.
What mysterious Palm secret am I missing here.

Any help very much appreciated.

Barry

try to change your SndDoCmd to synchronous

SndDoCmd(NULL, &sndCmd, false);

Thanks vadim ti, yes I forgot to say I had already tried that and it made no difference. I should also add that I reversed the two parts of the script and got what I wanted but that is really not satisfactory as it is covering up something which is inherently wrong. Maybe the Palm OS is just full of bugs!

Cheers

Using code warrior 9.2 on Windows Xp. I have to admit that the above script runs fine on Emulator but I think it is slower so that's why it works. It's a strange result.

bravotango,

I tested your code with POSE as well as with my Palm Tungsten W, and Palm m125, On both devices it gives same sequence of Tone as it is on POSE, May be this is some other problem in your code that is causing this on your system. The behavior of device and POSE can be different in some situations, one main deference can be of speed.

The sound sequence on device should be assumed as actual sound sequence in your case because ultimately the program is going to run on device. Nevertheless, I wonder at the same time about the behavior on POSE.

On more thing I suggest you to try to clear all doubts is, create a new application and insert this code fragment in this application as I did, if there is some problem in other part of your code that is causing this, this code should behave proper on new fresh application.

Regards,
Manpreet

One more thing I would like to share with all is that following two statements makes no difference at all bacuase last parameter is not implemented on Palm yet.

SndDoCmd(NULL, &sndCmd, true);
SndDoCmd(NULL, &sndCmd, false);

>>>I should also add that I reversed the two parts of the script and got what I wanted but that is really not satisfactory as it is covering up something which is inherently wrong.

You are right Barry, We should never cover up any error by folowing an approach like this.
>>>Maybe the Palm OS is just full of bugs!
Palm is not full of Bugs. Yes, this is true that, this OS is still evolving and had to offer many easier ways to do things.

When I started programming on that OS I had same problems. One thing of personal experience I share here about palm is, this OS is highly unforgiving. If you did a little mistake in some other part of your code, this may work for some time but starts giving errors suddenly, or may be in some other part (a type of chain reaction I call it) . You may not simply figure it out easily.

Best wishes,

Manpreet

Hi msjammu,

I accept your answer as being correct and as usual spot on. The error was somewhere else in the code. I changed a few things which had nothing to do with this problem and now it works perfectly on POSE and on the device so I must apologize for wasting everybody's time.

I must get out of the habit of blaming Palm OS everytime something does not work as expected.

Cheers for now,

Its nothing about appologize for wasting everybody's time. But now everybody who reads this thread will be a littlebit caring when dealing with sounds.

Thanks & Regards
