Thank you for your PR!

I will check the PR on my environment. Please wait a few days.

In Windows 11, it was confirmed that multiple VC interfaces were correctly enumerated by applying the PR, but it failed without the PR. LGTM.

Just a heads up, the pre-commit action is failing. I'm not sure if we should go ahead with the merge. Could you check it out when you get a chance?

I have confirmed that it is possible to capture 2 streams simultaneously using the following example.

I've confirmed that the pre-commit has successfully run on my local WSL machine. In my estimation, I believe the reason why the GitHub action's pre-commit failed is due to the test environment. I think there are no issues with this PR.
