Blue sound Pulse Roon EQ

Hi everyone,

I have a Bluesound Pulse that I use as a “kitchen” speaker. I would like to use REW to take some measurements then use Roon to import those filters for the speaker. The Pulse has an 3.5mm audio in and I get conflicting information on internet searches if it is a viable way to loop the REW signal. I have used REW a little in the past but when I try the 3.5mm audio in to my laptop it doesn’t work. Thought about using Bluetooth from the computer to the speaker but that doesn’t seem ideal.
My question is has anyone imported REW filters into Roon when using a Bluesound or similar speaker?
Thanks
Scott
