Please describe your issue in as much detail as possible:

In-game voice feature no longer reacts to voice input. DOTA is relying on the voice settings from the Steam client and whenever you try to configure voice settings in DOTA the user is re-directed to the Steam client. However the voice input works as expected in the Steam client alone but it seems like this feature has been re-worked with the new tab "Friends & chat". Notably is that the re-direct from DOTA is sending the user to the "legacy" tab for voice settings which is no longer available from the Steam client alone. This raise the question are there multiple APIs for the voice feature which DOTA is relying on and is DOTA using a deprecated API?

Anyways it would be nice with some insights of how Steam and DOTA is accessing sound resources since there's multiple ways to configure this in Linux.

Steps for reproducing this issue:

1. Start DOTA2
2. Go to Settings -> AUDIO
3. Speak and observe if your voice is registered in "Current recording level"
4. Click "Steam voice settings"
5. Navigate to "IN-GAME VOICE"
6. Verify "Recording device"
7. Press "TEST MICROPHONE"
8. Speak and observe if your voice is registered

(In-game when pressing Push-to-talk the "voice bubble" on the right hand side is crossed, indicating that the voice is not working properly)
