Hi! I updated my MacBook Pro 2015 to macOS sierra (10.12.3) and now I get choppy audio output with my Toneport UX8. There are a lot of short gaps and listening to music or watching video is really a pain. I tried it with different audio programs. Even the system sounds are choppy. It worked well with El Capitan. So it must be a problem with the new OS version or with the drivers. I already downloaded the latest driver version 7.6.7 but it didn't help. There are no other programs running which could interfere with the audio output. CPU usage is very low. Is anybody else experiencing the same problem with UX8 or another Toneport or Line6 device? Is there anything I can do to fix this? Any help is appreciated. Thanks a lot! Michel
