something for the todo list

roppp · Nov 28, 2003, 09:07 AM

I would like to see the issue

"The system might fail to go into Stand-by / Suspend modes based on inactivity timer. "
(from the know issues list on http://kxproject.lugosoft.com/issues.php?language=en)

on the todo-list. I did not found it in your list at
3536 rc2

I know, this is not really a big issue, but for me it would make the drivers much more usable.

Thanks.

unfortunately, I currently don't see any affordable solution, since kX Mixer really needs to keep the device opened all the time

(and there's no known way to 'say' to m$ windows to ignore this)

What about exiting the mixer app on standby and restarting it on resume?

If I have Cubase SX running and I go to standby mode (suspend-to-RAM, the most awesome standby mode ever) it loses sync with the card and I have to exit and restart it... not such a big deal, but a little bit annoying.

Thanks Eugene.

one can write a third-party tool to 'close' kX mixer automatically, enter the system into 'stand-by' and re-load kxmixer on system 'awake'...
it is -theoretically- possible to add special internal timers into the kX mixer, too -- but... this will require to set-up standby timers in -kxmixer-, not windows control panel... I doubt that's a good solution
(that is, I doubt kX Mixer really needs a special 'Power management control panel'

)

This could be done easily with girder (www.girder.nl). Girder gets an event when the system is going into stand-by or when the system resumes.
But, this does not help with the issue that disables stand-by based on inactivity timer.

Which device? I can remember a thread where you found the kx-control device responsible for this issue. Is there no way to disable this device (permanently) if I don't need it? Perhaps you could add an option or a commandline switch to disable it. That would be very helpful.

the 'kx control' device is used for remoteir, kx automation and kernel<-> mixer communication
disabling it will affect kxmixer functionality...

you can, anyway, try to disable the device in the control panel
(don't forget to unload kxmixer before disabling the device)

I don't have a remote port on my live platinum and I don't use automation. But I guess that I need the kernel<->mixer communication although I don't know what this is.

Anyway, I like to test this but I did not found where to disable the kx control in the control panel (should it be in the device manager or in the sound settings?) May you could point me to where I can disable it? Thanks.

BTW. I am using WinXP pro.

Well, I suppose that the mixer is getting power notification messages? Can you close the device when you get WM_POWERBROADCAST and reopen it when you get it again?

**Eugene Gavrilov** · Dec 3, 2003, 02:05 PM

the 'WM_POWERBROADCAST' event is sent to the kX Mixer -after- the system has determined the 'standby' timer had expired

kX Mixer tracks this event and resets kX Control device on 'standby' / 'resume'

>> May you could point me to where I can disable it

hmmm it seems it is no longer listed on the 'properties' tab of the device manager window... strange...

you may need to disable it manually (via the registry) -- sorry, I cannot guide you at the moment

No problem. I guess I can find out myself how to disable it in the registry.
I only wanted to make sure that I'm not blind...

>> 'WM_POWERBROADCAST'

returning to power management stuff -- if anyone is familiar with Windows SDK/DDK and has any ideas about this issue -- let me know

if you find a convenient way to solve this issue -- please post it here for our users to know

In a first attempt I simply deleted all registry entries containing 'kx control'.
After a restart I found the issue not going to stand-by on inactivity timer solved.
But as Eugene promised there was no more automation (not much problem for me). Also the headphones plugged in didn't mute the headphones (and this was a quite nice feature). So it would be great if there is a better solution than this one...
