So Windows mic passthrough works without the user installing anything: when no virtual-mic
device is present, install Steam Remote Play's SteamStreamingMicrophone.inf (ships under
Steam\drivers\Windows10\{arch}\ next to the speakers INF Apollo uses) via DiInstallDriverW
loaded from newdev.dll — the same mechanism Apollo uses for Steam Streaming Speakers — then
re-find the device. Needs admin (the host runs as SYSTEM); best-effort and safe (no-op if
Steam absent / INF not found / PUNKTFUNK_NO_MIC_INSTALL), falling back to the manual-install
guidance (VB-Audio Cable) otherwise.
Not yet built/validated on the box (down); FFI cross-checked against windows-0.62. Whether
Steam ships SteamStreamingMicrophone.inf at that path is to be confirmed on the box.
