Devices no longer scan for channels

pcostanza · 2022-09-25, 12:59 AM

Recently all my recordings from my ATSC tuners didn't record. Live tv was working but I tried to rescan for channels and nothing happens. I've deleted all the channels and tried to rescan and still nothing happens. I've done nothing at all NPVR for the last year or so but update when updates are out.
Logs attached.
Thanks.

Your tuners are not available in your system, so NextPVR is unable to use them.

ie, I'm not sure if you've uninstalled the SiliconDust drivers, or it's happened because you've updated the SiliconDust software, or whether the drivers can't detect them on the network so isn't creating the tuners. Maybe restart NextPVR (or your machine), then look on the Settings->Devices page to see if they're listed, and whether they're marked 'unavailable'

Thanks, that didn't seem to work. There were some updates recently from Silicon and maybe that caused the problem. I think I will try removing and a reinstall and see if that works.

Reinstalling NextPVR would make no difference to this. Reinstalling the full SiliconDust HDHR software may help (since it recreates the drivers) https://download.silicondust.com/hdhomer...indows.exe

Got it. No luck. The Prime tuners seem to work ok with NPVR but of course, only receive the channels that are not DRM locked. It's just the ATSC digital tuners that aren't working.
I checked a second system I don't always use and the same thing has happened. Obviously some update by Silicon has caused problems.
Thanks for your help.

When you run the HDHomeRun Setup utility, do you see your ATSC tuners listed?

Yes in the setup and in the GUI. I'm running a scan in the setup again to see if that clears it up.

No joy!

Can you restart NextPVR service, then post the logs? I want to see the device detection that happens at startup.
