This is an older h9. It’s very difficult to pair with Bluetooth and I’m wondering if because of its age it doesn’t switch settings well?
When was the last time you updated the firmware? Does H9 Control say you are on the latest version of the firmware?
You can verify the settings from the from panel by going into the System Settings.This video shows you how to access Systems Settings from the front panel: https://youtu.be/OiAkgc_44Yw
Instead of going into the Utilities menu, however, navigate to [AUX SW] and verifying that [PR+], [PR-], and Performance Switch (hot switch) are assigned to TIP, RING, and T+R correctly. Page 34 of the manual shows you the possible assignments.
