Please describe your issue in as much detail as possible:

While in an active voice channel, the Quick-Access Menu provides user with an option to Mute Mic / Mute Voice with X. Once triggered, X prompts the user to Reset To Default, however pressing it does nothing. To unmute, you therefore have to press A to adjust the slider, move it over by one and then press X.

Affected Platforms

• LCD / Jupiter: Yes
• OLED / Galileo: Yes
• Desktop Deck-like session (gamescope -e -- steam -gamepadui -steamdeck): Yes
• Desktop: Yes, in Big Picture Mode

Actual result

• Reset to Default does not function and the devices remain muted.

Expected result

• Reset to Default serves as an unmute button when the device is currently muted. This should return the device to its pretty gain level.

Notes

• On Steam version 1725412627 and older on Desktop (Big Picture Mode or Deck-like session), the user was instead presented with an Unmute option instead of Reset To Default.
