ASIO plugin - Issue with Channel 4

[Streamia.gr]

Windows 10 - OBS 27.1.3 64 bit - ASIO plugin version 3.1.0 - Audio device Yamaha Steinberg UR44C USB

The problem:
Channel No 4 is not recorded nor streamed.

Description:
I tested this issue in several ways, getting into the same conclusion.
Used 4.0, 5.1 or 7.1 multichannel audio. Although, in all cases, I see a volume indicator on audio mixer, channel 4 is not monitored, recorded or streamed.
This was not an issue or prior version for OBS 26-.

Really unique situation! Any suggestions?

Regards.

Major revisions of obs can break abi compatibility with older plugins. That sounds like what's happening here, download the latest release for v27, see if that helps.

I'm already using version 27.1.3.

Yeah sorry didn't double check, the description reads exactly like an abi break, ages ago the volume meter didn't display meters correctly, can't remember if that was fixed. If you're saying between v26 and v27 the plugin stopped working, that's going to be obs at fault, there shouldn't be a significant functional change to the plugin, assuming you're downloading the ones built with the same library. Pretty sure we released the new plugin specifically because of an abi break, to be through, make sure there's only one install of the plugin, / one .dll and let me know what version you were originally using in v26.

He is pretty sure that it is an OBS issue, not plugin's issue.
Any ideas, could any OBS developer to verify?

Thanks.
