Extras Tuners Not Loading on NextPVR 3.1 Linux Install

[Siftingice]

I've been troubleshooting Extras tuner integration on Linux with the latest nextpvr-helper.deb package (v3.1) and have run into what looks like a complete absence of Extras support.

Environment:
- OS: Ubuntu 22.04 LTS
- Architecture: amd64
- Mono: 6.8.0.105
- NextPVR: 3.1, installed via official .deb with --install-recommends

Extras Config:
I've created /var/opt/nextpvr/extra/extras-hdradio.xml containing:

<Extras>
  <Extra>
    <Name>HD Radio SDR</Name>
    <Executable>/home/brian/GetHDRadio.sh</Executable>
    <Arguments>{frequency} {subchannel}</Arguments>
    <Type>TS</Type>
  </Extra>
</Extras>

The script exists, is executable, and runs independently. Permissions are correct.

Confirmed:
- <ExtraDirectory> is present and correct in config.xml
- XML file is valid and readable
- Manual server restarts performed

Issue:
- No log entry about loading extras-hdradio.xml
- No Extras tuners shown in Devices tab
- No API trace from /service endpoint
- Purged install and reinstalled from official .deb, recreated files

Suspected Cause:
It appears the Linux build is skipping or missing Extras subsystem entirely. Windows build loads the same file without issue.

Question:
Can you confirm whether Extras support is enabled in current Linux builds? If not, is it planned, or is there a workaround?

Thanks!

They should work when you put them in the data folder directly and not a sub directory.  I don't know anything about a config.xml setting to change the folder
