Failed FlexASIOTest, failed to open in ableton

[rafa3lico]

Hi, I installed FlexASIO GUI to make the device identification easier. Selecting the "FlexASIO" audio device in ableton 10 gives the error "failed to open the audio device "FlexASIO.""

I checked some of the other posts, so I attempted for example to edit the .TOML file to just

[input]
device = "Microfone (UMC202HD 192k)"
[output]
device = "Altifalantes (UMC202HD 192k)

And this allows ableton to select the device, but it says that the audio engine is still off.

I ran the FlexASIOTest just to check and indeed it also fails. Any ideas?

FlexASIOTest console output.txt
FlexASIO_trying to open in ableton.log

Here I attach the console log of the test result and the logs i get while trying to open in ableton. Thanks a lot in advance!

Perhaps this can ease some analysis, perhaps not, but here are some lines of the logs which seem relevant:

Using the full toml generated with FlexASIOGUI:

backend = "Windows WASAPI"
bufferSizeSamples = 256

[input]
channels = 2
device = "Microfone (UMC202HD 192k)"

[output]
channels = 1
device = "Altifalantes (UMC202HD 192k)"

It's finding the devices:

I Noticed issue #94 had the same error as me but I checked that the number of channels in my input is correct.

[rafa3lico]

using "KoordASIO" worked. I figure this is relevant since it uses FlexASIO. Let me know if there is any way to get logs from KoordASIO which may help here

Mmm yeah I'm not sure what's going on here. DirectSound fails to start with a cryptic error:

using "KoordASIO" worked

It is extremely surprising that KoordASIO would work where FlexASIO would fail, on two different backends no less, including DirectSound (which should always work).

Does it work if you try to use different devices? E.g. if you just use an empty configuration?
