I dont think you do need a switcher.

Got this in hopes of the auxiliary jack that it comes with working. Looks like I’ll plug it directly into the laptop-aux cord to Astro base station. Hoping that’s the answer! Okay thanks for some insight. Had no clue about CTIA or OMTP
edit, 6.39€, this one was the one I ordered - but I don't want to promote anything, buy the one you like, there may even be cheaper ones - but this one works flawlessly on my brand new xmg laptop :) https://www.amazon.de/gp/product/B06Y433C3S/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
and by the way, last week I also tried to use my razer headset like this, without the splitter, what works is you can use it either for only the sound or only for the mic, flawlessly - I had sound via the headset and communicated via laptop mic, also no problem, the mic is not bad (I think it's the same on the Fusion 15)
I tried the adapter, didn’t work: Headset Splitter Cable, CableCreation 3.5mm Female to 2 Dual 3.5mm Male Audio Y Splitter Cable with 3.5mm Audio Jack CTIA to OMTP Adapter,Black and White/ 0.2 M https://www.amazon.com/dp/B06Y433C3S/ref=cm_sw_r_cp_api_glt_i_BE2KSY6PD1CJNZK73E23?_encoding=UTF8&psc=1
Tried an AUX To USB adapter which didn’t work:
DUKABEL USB to 3.5mm Jack Audio... https://www.amazon.com/dp/B07RS11M1T?ref=ppx_pop_mob_ap_share
And lastly a ground loop adapter which didn’t work:
BESIGN Ground Loop Noise Isolator for Car Audio/Home Stereo System with 3.5mm Audio Cable https://www.amazon.com/dp/B06XQYN77L/ref=cm_sw_r_cp_api_glt_i_BTC34Q42PMF2YYJJ01WJ?_encoding=UTF8&psc=1
Any other ideas or am I just out of luck?
