I am not from Laminar Research; just a flight simmer from down under.
I am not able to answer your sound problem however if you follow the advice given in the following link you will be able to attach your log.txt file.
The link can be found at https://questions.x-plane.com/?qa=blob&qa_blobid=17830136656522860642
Had a look of the log.txt file.
Cannot recognise your problem as my knowledge base is not fully conversant on how to interpret the file. But found some observations.
1. Update all of your drivers. This may be a simple solution to your problem
2. Have you read the XP10 user manual. I am of the opinion your installation may be incorrect. It certainly does not follow a windows installation. The manual may be found at https://www.x-plane.com/manuals/desktop/10/ To expand the chapters click on the [show] button located on the RHS of the index. Although I have not fully read the manual I am of the opinion there are sections specifically for Mac installions.
3. How have you installed the logitech joystick? If not through X-Plane then have a look at a lengthy answer I provided in another posting
What you need to ensure is you do not assign two processes to the one button or slider and make sure you do not assign more than two buttons or sliders to the one assignment.
Just realised the instructions I have given relate to XP11. Why don't you change to XP11? A lot easier to use than XP10. I also recognise your system may not be capble of running XP11.
Although my comments may not solve your particular problem it may go a long way in making your system run smooter.
