Streaming from Phone 2

Hello. I've been looking at ways to stream mobile games from Razer Phone 2, with no true success. The closest I got was through the Vysor app, but it loses audio mirroring quite often mid stream. So it came to me I could use my capture card, which would be much more consistent. To my tremendous disappointment, the uni HDMi adapter I bought seems to be incompatible with the Phone 2, causing it to freeze until I unplug the adapter, so now I'm back to square one. I've read there are a few HDMi adapters compatible with the Phone 2, yet it appears those items have mixed reviews, and Razer users reporting mixed experiences. I'd like to avoid wasting more money on stuff I won't end up using. So I'd like to ask, has anyone found a way to consistently stream screen and audio to a PC without notable issues? Are there any good adapters that work with Phone 2 in this current Android version so I can use a capture card?
