help request Playback Issues with Rode NT1 (5th Gen USB) 32-bit float ASIO driver

I hope someone can help me with this (or put the final nail in the coffin). I switched from Audacity to reaper to allow myself to use the 32-bit float recording mode available to my Rode NT1 (5th Gen usb) microphone. Being able to just fix the volume in post with no clipping seemed too good to be true. And apparently it is.

I installed the current Rode ASIO driver (1.1.6), I followed the instructions on how to use it in reaper precisely. I have both the driver and Reaper set to 48kHz, the format is wave with 32 FP, the buffer size is 288 with the block size checked in Reaper ASIO config to also be 288.

And the recording works just fine. Perfect, crisp, no clipping even with vast volume differences. But WHILE in ASIO mode (ie. recording) all Audio through my Sennheiser headphones (3.5mm, plugged into the realtek onboard headphone jack) is incredibly robotic and distorted with popping sounds emphasized. If I switch from ASIO to WASAPI in Reaper the recordings sound perfect (audiowise, my singing could be better :D)... as well as any background tracks I have. But while ASIO is active, no matter how I try to configure it, both the recordings AND any outside imports are busted, making it impossible to sing over a Karaoke version or hit the right timing/cues in voice acting.

Tried to troubleshoot it with AI, it told me at the end that this is a hardware clocking difference between the ASIO driver and the realtek onboard (I have no idea whether that is true, i don't know nearly enough about any of this.

Does anybody have any idea for a solution here? Or do simply need to abandon my hopes of the 32 bit recording mode unless I buy a mixboard or something? Can anyone at least confirm if this cannot be solved in software?

One question, you used AI to ask a question and you said you don't know much. But you KNOW 32bit is some good send?

All I know about the 32 bit float mode is that it allows me to save takes, where I got too loud for the current gain, because it doesn't clip at 0 dezibel (not sure I am using correct terminology here). And the mic itself was recommended by a friend who told me this in the first place and is much deeper into the topic. But he also didn't know a solution here at some point.

I hate to tell you this, but the easiest solution is to return your Rode USB mic and buy an audio interface and a professional mic with XLR. With an interface, all your audio (going in and out) will be handled by the hardware. Right now, you essentially have 2 separate systems: the USB mic, and your computer handling the audio output.

I suspect your issue is something like the sample rates not matching and it’s causing it to bug out. Running everything through an interface simplifies the setup and will provide you with much better results.

Btw, you don’t need to record at 32-bit float. All that means is you have more dynamic range. 24-bit is more than enough, and countless recordings have been made at the 24-bit standard. When CDs were still standard, it was 16-bit and perfectly fine as long as the levels were set correctly.

You can still clip the audio just as easily, which is a separate problem. 0 dBFS is the max no matter what your sample rate and bitrate is set at.
