Best practices for resolving sonypvu1 issues

A clean and tidy computer is the key requirement for avoiding problems with sonypvu1.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem.
