DCS crashes when SteamRV turns off displays

Recommended Posts

I went from CV1 to G2 and one thing that caused me grief was that I could not pause my game and take off the headset (to answer phone, doorbell etc) for longer than 5 minutes. As soon as SteamVR turns off HMD displays, DCS just quits! I see this in the end of the log file:


2021-01-04 15:07:58.612 ERROR   SOUND: IAudioClient::GetCurrentPadding failed: 0x88890004 (AUDCLNT_E_DEVICE_INVALIDATED)
2021-01-04 15:07:58.961 INFO    SOUND: Opening default audio device.
2021-01-04 15:07:58.965 INFO    SOUND: Driver reports 2 channels with mask 0x3
2021-01-04 15:07:58.965 INFO    SOUND: Using 2 channels at 48000 Hz
2021-01-04 15:07:58.965 INFO    SOUND: Channel layout: Headphones/Stereo


This is particularly a problem for long missions, like in Raven One campaign.


I found a temporary solution to increase the off timeout to one hour:

1. With SteamVR running open in the browser http://localhost:27062/console/index.html

2. Run this command: settings power.turnOffScreensTimeout 3600

I'm interested to see if DCS can implement a fix for this themselves as I too would love to see a fix within the game itself.


My workaround is to have a business card that I lean against the headset (on the inside) to keep it turned on. The workaround you have is much better - I don't have to 'remember' to put the card in and come back to a crashed game. Thanks for sharing!

Actually, now and then I experience DCS quitting for no apparent reason (no crash dialog), with similar errors in its log:


2021-01-05 15:42:47.655 ERROR   SOUND: bufferEvent has timed out.
2021-01-05 15:42:47.830 WARNING LOG: 1 duplicate message(s) skipped.
2021-01-05 15:42:47.830 ERROR   SOUND: IAudioClient::GetCurrentPadding failed: 0x88890004 (AUDCLNT_E_DEVICE_INVALIDATED)

Other VR games are running smooth on my PC (Alyx, MSFS, Google Earth VR, etc). Is DCS too sensitive to some G2 hardware latency?


Devs, please look into this!
