@rezeroenthusiast Check the mod's documentation: Mod developers may offer information about known bugs and fixes in their documentation. Look for mentions of the missing clicking sound and possible remedies.
Contact the mod developer. If the documentation doesn't help, consider contacting the mod developer directly. They may be aware of the problem and have a solution or advise more troubleshooting procedures.
Check mod compatibility: If you're using numerous mods, make sure they're compatible with one another. Conflicting modifications can also result in unforeseen difficulties, such as missing audio. Disable other modifications momentarily to check if the clicking sound reappears.
