Stopped working after an OS update
These are general checks, not model-specific compatibility certification. Start at low volume and change one setting at a time.
Check in order
- Record the previously working OS/software versions and current versions.
- Check official compatibility and known issues. Newest does not necessarily mean compatible.
- Avoid mass updates before a gig or unplanned downgrades. Verify backups and the official recovery path.
- Check the hardware, software and OS compatibility together. Some models are driverless; install only drivers required by the official model page.
- Record original settings, change one thing at a time and compare the same 30 seconds. Avoid updates or resets during a gig.
- If unresolved, record hardware, OS/app versions, trigger and test results in the support note. An untested step is not proof of a fault.
If unresolved
Record hardware models, OS/app versions, the last responding meter and test outcomes for official support. Do not infer hardware failure or a purchase requirement from unverified checks.
