Many many years ago I had some really bad problems with my 17" Powerbook (I think that’s what they were called). Bad audio crackling that would happen periodically, across all audio drivers, including built-in. Eventually it was fixed, but it was a rough period.
Also had a real bad time with a MOTU soundcard and my last laptop (2013 15" MBP), which led to me getting the RME, but in reading the problems that people are having now, it sounds like exactly what I was getting with the MOTU interface.
With all the issues I’ve had with my 2017 machine, and seeing how generally shit other stuff has gotten (lots and lots of bugs, everywhere, that seem to never get fixed), I swore that it would be my last Mac laptop. Turns out that’s not strictly the case as it’s just getting turned into a 2018 machine, but this USB audio thing sounds like a massive deal breaker.
I’ll test things thoroughly when I get it, and thankfully I checked that the hub I bought when I first bought it is actually Thunderbolt, so hopefully that helps.
If I do have the audio problems, which I suspect I will from what I’ve read. I’m going to give them some serious shit, as they’d essentially be replacing my fucked machine, with a fucked-to-the-point-of-being-unfit-for-purpose machine. At least with my busted keyboard I can run an audio interface on this machine…
