I've recently updated my precision 5510 to windows 10 pro version 1803 build 17134.48 ... and I've been having sound issues since then: The audio has random glitches every now and then and it's very annoying, so I tried reinstalling the most recent audio driver from dell (Realtek-ALC3266-3246-High-Definition-Audio-Driver_RYY5N_WIN_22.214.171.12433_A08) which didn't help with the issue, and also removed the Dell Audio software! Now I still have the random glitches + missing dell audio software, and now I can't configure my machine to use the mic in my 3.5 mm analog headset!
Update: I've found the dell audio software under: C:\Program Files (x86)\Realtek\Audio\Drivers\HDADrv\WIN64\RtkNGUI64.exe !! Rather inconvenient that it's not DellAudio.exe or something, and of course it doesn't come up in the windows start menu search as it did before!, rather annoying to reach really.
