I've read somewhere that Windows audio mixer settings can influence level meter readings of Lightworks audio mixer and even export audio level.

I cannot imagine that this is true, is it?

Just to explain the reason for my question. All my test show that Windows mixer settings have no impact to Lightworks audio levels or meter readings, except of the audible preview signal.

But if somebody knows a method to show that Windows mixer settings exist which can affect Lightworks audio levels in any way, except of audible preview, I can imagine that devs would appreciate to know about it, because it might be considered to be unexpected behaviour.

Muting the windows audio device has no impact on LW levels they play normally - of course if the windows device is mute and one is using the output of that device to monitor sound then nothing will be heard.

An export while the Windows sound device is muted again obviously can't be heard on an external player while the device is mute - restore windows device levels and the export-while-muted file has normal sound.

Even unlikely questions can be answered - though pretty obvious what the answer would be.

I'm, asking myself how the contributors of the information I've mentioned above have managed to influence the internal chain with the mixer.

Anyway, those who know may answer.

Win 10 audio device settings can influence export recording levels external to Lightworks. I discovered the settings related to this when trying to reproduce Hugly's level error "bug".
Under my normal settings it does not, but I run everything at 24 bit 48K studio format. It did when I ran Hugly's 16 bit test file through test recordings. It took a bit of searching to find out why. The pictures show the relevant settings. This does not apply to external hardware audio interfaces with separate recording and monitor outputs. Only to the system audio device, in my case a Realtek Hi Definition chip set. This is a design property of the Windows audio device and not a bug in either Windows or Lightworks.

First, the system master volume control will reduce the level of files exported from Lightworks if it is set to less than 100% under some conditions. If you export different sample rates in the same project, this MUST BE SET TO 100% along with the app volume level. I.E. everything at unity gain. Monitor volumes must be controlled externally not using the Windows sound device. If you do this levels in exported files will match Lightworks mix out meter readings. This is what I discovered with Hugly's test files.

If your run the Windows audio device at a user selected default sample rate, You can set app priority for that sample rate and the system master volume does not affect Lightworks exports. But Lightworks export sample rates must always be at the default setting.

The Windows mute function is separate and has no effect on Lightworks recordings. at any setting.

Win 7 has a "when Windows detects communication activity"
- mute
- a couple of levels of reduce
- do nothing
as choices. Not on Win10 right now - is there an equivalent.

AFAIK Win 7 does not have application specific settings - or I can't find them

On systems with I/O cards all control is ceded to the card through which one expects to be able to configure sound parameters and expects they will be universally implemented - here all sound I/O is via SDI. Not very much call for Input these days and we extract from SDI on the desk for monitoring.

Communications settings are still in there RWAV.

Not sure, is that a trap for young players or part of the 'mute does not impact on LW levels' paradigm?
Might that impact gamers who elect to play-on while LW is rendering a quite long screen adventure?
Indeed how might Microsoft define 'communication', I'd guess skype would qualify?

Communication is VOIP or soft client video conference calls. Don’t think it has anything to do with in game headset coms.
