Alright for some reason I can tune my pc's audio just fine by adjusting the global operating system output sound. However, when I go into volume mixer I don't see any green bars for sounds from any program (including on the global sound column) and any attempt to adjust sound for a specific program is completely null and void. All drivers are up to date - just got this computer. Motherboard is Asus Z170 Deluxe, using the onboard sound with Logitech Z623 speakers.
