Jorge,
When I bump the edge of the screen and the dock appears, I click on an icon to launch an app. After the app is starting to load, the sound (show/expand, hide/collapse) finally plays. Is this a problem with Win 7 or is the problem with Nexus 10.4? Other Windows event-triggered sounds seem to be virtually instantaneous.

Just curious,
Grouch

Are you saying you only get the expand/show sound when you actually launch an application and not when you actually expand/show the dock?

Have you checked the Sounds tab in Preferences to make sure sound associations are correct and have not been changed?

Jorge,
The sounds are correct in the configuration. I'm saying there is that much delay from the time I Bump|Launch. It play all of the sounds, in order, (Show/Expand, Launch, Hide/Collapse). It's just that there is quite a bit of lag-time before they are played.

Hope that clears it up,
Grouch

P.S.
All drivers are up to date.

This is not a Nexus issue per se.

Try the following: keep some music playing in the background with Windows Media Player. Now show the dock/lauch an app. Do you still get the same lag between the action and the sound playing?

Jorge,
Aren't the sounds being played by audiodg.exe? I would not normally have the WMP running in the background. The less running the better.
I'll have to try that as a test, but I don't have any media files to play in the background.

Thanks,
Grouch

No idea what plays them, Nexus just sends the sound file to the proper API, then it's up to Windows and the sound driver to play the sound - and yes, the Media Player thing was meant as a test.

Google for "lag playing sounds" and you will probably see what I mean.

I'm 100% sure that it's not a bug with Nexus (never heard of this issue before, in fact), and probably not something that I can fix or work around, but rather something specific to your system.

The only thing I can do is help you troubleshoot a bit until you find the real cause.

is your system being sluggish or nexus being sluggish to show sometimes when you bump the screen edge? i found that if i am running high demand programs that the nexus edge bump sound can be delayed by about a second or two. in my case i believe it is a windows issue and not a nexus issue.

krazdkiller,
In my situation, I don't have any apps running. so that rules out system load. Per Jorge's suggestion, I did a search on "sound windows 7 latency". Got a lot of hits. I've seen some of the issues addressed by SP1(when/if it gets released), and sound synchronization is one of the issues. Evidently there was some issue with the API responsible for sound. Hopefully, the problem will go away with the release of SP1.

Grouch, i got to see or should say a got to hear what you mean yesterday. i have a much older program called desktop architect for adding sounds to system events along with various other gui tweaks. the events that sounds are added to by da i noticed yesterday had about a half sec delay between me performing the function and the functions sound. since these sounds have nothing to do with winstep i have to agree with you that it is an issue with 7. and this time almost nothing was running, so system load had nothing to do with it this time either.

Jorge,
Is there a chance that the WsxService interface is causing the delay in the sounds? Normal Windows events seem to trigger instantly, but you said you needed the WsxService to interface with Win 7 and Vista.
Just thought I'd run it by you.

Thanks,
Grouch

No, WsxService is only used to perform tasks that require admin rights - playing a sound is not one of them.

Sorry, but still no cigar...

Jorge,
Believe it or not, after getting rid of 'PCTools Threatfire', the sound latency problem is gone.
That's two problems resolved by getting rid of that infernal software. This may also be a problem with the other code-injecting anti-malware software 'IoBit Security 360'.
Thanks,
Grouch
