tunefix-update
Bypasses the need to retune the HD-FOX/HDR-FOX by making appropriate modifications to the tuning data when required (instead of starting from scratch like a retune). This avoids the annoyances of retunes. To be effective, your tuning data needs to be up-to-date so that the package can start from a clean baseline. tunefix-update receives tuning updates in the form of package updates, which it does independently of the auto-update package. Use in combination with disable-dso for best benefit.
