Recently upgraded from a 2017 15" MBP to a 2019 16" MBP, and experienced very frequent drops in audio that require the usb cable to be unplugged and replugged back in to reset the connection.
I am now currently running the LCX amp portion of this dac/amp, via a FiiO E10K acting as my dac, using the exact same Micro USB cable that I had connected to the SDAC. I have no issues with audio at all on my MacBook using this FiiO dac. The usb cable is fine, and the amp itself still works great.
The SDAC portion however, clearly has issues with the new generation MacBook Pros (possibly other current generation Macs as well). You'll see lots of similar complaints on the SDAC discussion page with no real response from Grace Design.
I don't know who is at fault for this. Some might say it's Apple, some might say it's Grace Design. All I know is that my FiiO E10K works perfectly as a dac for my MacBook, and the SDAC doesn't. Just leaving this here in case anyone else happens to experience a similar issue.
joelfongI´m having a similar issue with the cable. I´ve already tried 2. I´m going to buy a new one if this doesnt fix the issue then it just does not work for me.
joelfongChiming in to echo the experience. SDAC works fine until I pause the music. Once paused and restarted, audio is silent until I unplug and replug USB.
