I'm pretty sure he has hit this same issue I've had for years now:

  https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263385

I've tried everything, OSS, external USB DAC, PulseAudio .. all of it has the 
same issues.  It's worse in firefox/chrome especially for 4k video.

I don't have a non-nvidia card to try in this machine so I'm not sure in the 
driver but you can hear clicks for example when a keyframe switch happens.  
Anything that causes a lot of video refresh creates the clicks they are softer 
at lower resolutions but more acute at higher.

I'm still on an older 14.1 and have not updated I was going to try that soon but 
none of the previous updates from 13 made any difference and two updates made it 
worse.
