How can I change microphone sensitivity in the newest Steam update

The ability to test your microphone sensitivity within Steam appears to have been removed with the new User Interface update. Previously, you were able to do this via following these steps, but this is no longer the case. You can however, still adjust the input and output volume of your microphone/headset. You can do this by:

1. Open up your "Friends & Chat" window via clicking the text at the bottom right of the Steam client
2. On the window that pops-up, click the settings wheel in the top right, and select "Voice."
3. Find the Input volume/gain and Output volume/gain controls to adjust your input and output volume.

There is one setting within this same menu called "Voice Transmission Threshold," which I believe is the new way of adjusting your sensitivity. There are three options for it, Off, Medium, and High. Unfortunately, there still does not appear a way to test if the sensitivity is what you want after adjusting this control.
