@Wolfshoek I expect this is now fixed when Tracker 1.7.1 firmware update is available ? Did your freeze also have same characteristics as “Randomly freezing during playback with a buzzing sound at the output”? If yes, I will cross it off from your original post, to keep the focus on the issue described in the title.
For future, please read How to report bugs, and don’t report multiple problems in one topic. This helps us keep the relevant focus and be more effective in delivering bug fixes to you. Thanks again for your report and patience while we resolve it!
