I haven't even started migrating my strategies from WL6 yet, so just getting familiar with the interactive tools.
I find that the default Alarm sound set in preferences is not firing up in any of the following events:
- Price Trigger being fired and placing an order
- Tradable Trendline trigger firing and placing an order
- Live Order Stop LIne being triggerred in the chart and placing an order.
I checked and the option in Preferences>Sounds is not muted for alerts.
However the New Bar in Streaming Chart does sound with every chart every minute.
I remember the first day I did hear the alarm when an order was triggerred, but now that I have set a number alerts in the streaming charts the sound doesnt come through. I didnt change the sound file.. its still the default one Alarm.wav
What should I have a look? Sounds for orders placed are critical for me to verify execution.

Rename
You did say, "is not muted for alerts."
But just to be sure, that means everything is unchecked, correct?

Yes Correct.
If I go to the folder that contains the .wav files and play the alarm.wav file it plays properly as well as the other files.
The sound just doesnt play when orders are automatically triggered

My computer has the same problem. What was the solution.?
I want to bring back on top.
I still experience very unreliable use of sounds triggerred from tradeable trend lines or orders. What can I do to make it work consistently? Or can you guys confirm that it is a bug int he application?

All my WL sounds work fine. But you should be aware there's a known Windows problem with piping intermittent sounds through HDMI and USB ports on Windows. These device drivers go to sleep if they're not being used. That's not a problem if continuous sound is being playing through them, but it is a problem for intermittent alert sounds.
Microsoft knows about the problem, but keeping these device drivers constantly alive so they can work with sudden sounds is an OS scheduler overhead--and Windows is not a real-time OS (RTOS).
The solution is not to use HDMI and USB ports for playing intermittent alert sounds. What you should do instead is play your intermittent alert sounds through you integrated hardware sound card instead. It has hardware buffering and can capture intermittent sounds the hibernating software drivers (HDMI and USB) will miss--hardware buffering is key.
Happy computer engineering to you.
Thank you! That definitely explains what I am experiencing.
I wasnt awaret he thedevice driver for those devices coudl go to sleep. I was using a bluetooth speaker and that certainly explains why after a while the speaker reconnects.
I will try directly witht he local speakers of the laptop to see if it works better.

That's a better solution. A crazy option would be to play a 10-second jingle for an alert sound. Even if the first 3 seconds get cutoff, you will still eventually hear something at the end. But the long jingle will drive you crazy. :(
I agree with Microsoft; it's best to hibernate the HDMI and USB drivers if they are unused to speed up the responsiveness of Windows. Those are big drivers and they consume a great deal of overhead.
You might want to search a Windows hardware forum for other solutions users tried. Post a link if you find something interesting. There are probably other clever options for buffering sound service requests.
So I switched to my laptop speakers only and avoid all external speakers.
I am still seeing some odd behavior. I can hear the sounds for the following events properly:
- Save workspace
- New bar arriving
- Price trigger fired from the quotes window
However I do not hear the sound for the triggered order from a tradeable trendline.
I have configured the same .wav file for the save workspace event and the Trigerred Signal Alamr in Quotes, Streaming Chart and Strategy Monitor event.
The sound does work in the SAve Workspace event but when orders are trigerred from the tradeable trend lines no sound comes up.

As I suggested in Post #7, have you tried replacing the tradable trend lines sound with a 10-second long *.wav file? (You need to consider that the overhead the Windows scheduler sees on a "save workspace" event may be significantly different than a "tradable trend line" event.)
As I said, I would go to a Windows hardware forum and ask them for a compatible Windows hardware solution for your machine. If your machine has an extra PCIe card slot, it should be able to take the peripheral sound or USB card that can hardware buffer up the intermittent sound requests without the sleeping Windows software drivers getting involved.
If your machine can't take an external PCIe card, then you need to find a new computer that does, or a new computer with integrated sound on its motherboard that's managed by the BIOS and not the external Windows software drivers. Be aware, not all BIOS firmware vendors may buffer random sound requests correctly; try before you buy. (I like American Megatrends Inc as a BIOS firmware provider, but the Windows hardware forum may offer other choices when shopping for motherboard specs.)
What you cannot do is make Windows into an RTOS (real-time operating system). RTOS device drivers (like those in VxWorks that manage the real-time fuel mixture of your car) work differently than desktop device drivers (like those in Windows or unix).
I hope you learned something interesting about the limitations of operating system device drivers.
