I have a Hauppage single tuner running on OpenMediaVault. Plex finds the tuner just fine and it able to tune and watch all but one channel.
The channel has a main HD Channel (46.1) and two subchannels (46.2, 46.3). After the initial setup and guide data, everything looks fine. The channel data is correct.
When I tune 46.1 in the guide (web, Roku, Plex Media Player on a PC, Android), it actually shows 46.2 with the metadata for 46.1. (On a TV tuner it tunes fine). Similar on 46.2, it tunes 46.3.
When I try to tune 46.3, the server comes back with Channel can’t be tuned. At first I thought it was an issue with the signal, but it works fine on a regular TV using the same antenna.
What is even more strange is that after trying to tune 46.3 and receiving the can’t tune channel error, I can’t tune any channels at all anymore. I can stop and restart the Plex service, but still not able to tune any channels. I have to do a full reboot of the server to be able to tune any channels again.
It will work fine until I try to tune 46.3 again and then the same issue. It is only this channel as all other channels I can tune the .2, .3, .4 and even .5 on one channel.
Ideas?
