MP crashes sometimes after resume from Standby (1 Viewer)

Just got that message again when coming from STB and MP was frozen:

Ok setting "stop playback on removal of audio renderer" to "false" definitely leads to more crashes.

That's fore sure now

I have no set "MP always on top" to "false" - I hope that helps. Thats is also the setting user skurz has set.

ok that doesn't resolve the issues(s) either.

I have now done HDMI troubleshooting according to the wiki and set the resolution of my virtual desktop (when there is no HDMI connection) to 1080p just in case it turns out to be the resolution switching which kills MP - however I doubt that since I did reproduce that 20 times in a row once and MP did not crash. Furthermore MP seemed to do the resolution changes just fine in the log and crashed later on.

If it doesn't resolve the issue I am now running out of ideas for now.


As a summary for now I can say:

• MP can either crash on going into sleep or when waking up from it
• "stop playback on removal of audio renderer" set to "false" definitely leads to more crashes
• "Keep MP always on top" - can give an Direct3D error on resume which is different from the other crashes and happens rarely

Thanks and this is fuck..g issue for sure.

Ok setting the resolution of a virtual desktop/monitor does not help as I expected.

I am very sure it is related to adding/removing of the audio device.

I have added my EDID override again as it obviously wasn't the problem and did save me from blank screens a couple of times.

As for the freeze issue I am out of options for now.

It's related to Audio for sure.
I remember fixing some catch exception but surely need to add more.
Also the WIP branch (the latest you try) maybe need some improvement too (read here to be sure that all run in main thread to avoid COM object exception)

Hi

Ok one more log. This time there is an exception in the log, some value should not be "zero". It crashed while going to sleep.

Hi

1)
On my HTPC I have the "famous" iMon VFD with its iMon Manager software. So when I put my HTPC to sleep via remote the iMon software tell Windows to "go to sleep" and not MP via its GUI - could that be an issue?

If so, could a shortcut in MP be created for going into standby?

2)
What about a "dirty workaround" for this issue. In example an option to close MP when going into standby and restarting it when waking up?
Might be worth considering I think.

If so, could a shortcut in MP be created for going into standby?

It's there already. Arrow down on the MainMenu, select the PowerMenu (middle option), then option 5

Ok to be more precise: I mean a keyboard shortcut that can be used via iMon (I knew its there )
