Check the file-matching rule before changing languages
A subtitle provider may have entries for a programme while an automatic download finds nothing for a particular recording. The title alone does not describe the filter being applied. Note whether the problem affects all items in a library or mainly recordings and independently produced encodes, then examine the library’s automatic-subtitle options.
Configure the plugin, library and matching condition
Emby’s documented sequence is to install a subtitle plugin, restart the server, configure that plugin and then edit each relevant library with advanced settings shown. Choose the download languages and applicable provider. Require a hash match is a stricter condition: the media file must match the provider database’s file byte for byte. The official guide warns that personal rips or DVR files will not obtain that match. The Download Subtitles scheduled task performs the automatic work when a candidate is available.
Test an appropriate selection without promising a result
For an independently recorded interview with separately supplied captions, a catalogue search may not be the right source at all; the production’s own caption file may be the relevant material. For a recording with potential provider candidates, review whether the exact-file condition matches your intended search. If the condition is relaxed, inspect any resulting subtitle against the actual beginning, middle and end of the recording. Removing a filter broadens eligibility; it does not establish translation quality, accessibility completeness or timing. Keep the chosen language, matching option and provider in the support note so that later searches can be compared meaningfully.
Questions, answered
Does a matching programme title satisfy Require a hash match?
No. The documented condition is an exact byte-for-byte file match, not a title match.
