I'd also check memory (which Windows 10 at least could do on a reboot, so I assume Windows 11 can). Never underestimate how much effect a slightly ill-seated stick of memory can have.
The biggest wins for me with quietening my PC were a silent (fanless) PSU and changing spinning rust for solid state disks (the disks vibrated the case, even with more grommets than you could shake a stick at). With a fanless GPU, a "silent" case fan and a quiet CPU fan and all solid state disks, I can't hear the PC at all now - even though it's right under mu desk. Of course, picking a low TDP CPU (65W) which meets my needs helps too as I have less heat to disperse at any given time anyway.

Weird - YT refused to allow embedding this time...
441 is indeed not a power of 2 (2, 4, 8, 16, 32, 64, 128, 256, 512, 1024...). It's expecting to be used with an ASIO driver which (almost always) has a power of 2 buffer size.
What I see when I switch between devices on the same PC (MOTU in ASIO and my HDMI in WASAPI) is that if I have the hardware output set to the second output on the MOTU, save and re-open in WASAPI mode, then since there is only one hardware output on the HDMI, 2 doesn't map to anything, so the output is set to -- Nothing --. It's irritating, and I've been bitten by it a few times in the past.
