Hi there,
Thank you for posting this.
I understand how troublesome your issue is, especially since your mic works perfectly on Discord but becomes very quiet as soon as you switch to in‑game voice chat.
This usually happens because Windows detects in‑game voice as “communication activity” and automatically alters audio levels, or because the game takes exclusive control of the microphone and bypasses the gain that Discord applies, which makes your voice sound very low even if the volume is set to 100%. Microsoft recommends setting Windows to Do nothing in the Communications sound settings so it doesn’t change audio during voice activity, disabling exclusive control for your microphone so games can’t lower its input level, and confirming that microphone privacy permissions allow desktop apps and games full access to the mic, as restricted access can cause low volume only in games. Microsoft also notes that many games use their own input device and mic gain settings separate from Windows and Discord, so you must manually select the correct microphone and increase voice gain inside the game itself for normal volume.
