TVHeadend not finding all channels

Added by jimbo 34 about 8 years ago

I’m running TVheadend server and client on a Raspberry pi 2 with openelec 6.0.3 (Kodi 16). I can get it up and running ok to watch and record but have an issue where the channel scan is not picking up all the available DVB-T channels. I'm in Spain and have entered the list of muxes manually. The same list picks up all available channels on my samsung TV so it’s not the aerial or connection. I have been using a Realtek RTL2832U + R820T USB adaptor plugged directly into the Pi. When plugged into a W10 laptop the same adaptor picks up all the available channels so I dont think the problem is with the receiver. The pi is using a 25000ma supply with max_usb_current=1 so I don´t think its a power issue. I think that leaves me with a problem with TVheadend. Any Idea how I can force it to scan the missing channels or any other Ideas on what the problem could be?

I have the same problem.
My setup is unRAID running tvheadend docker, with Hauppauge WintV-Quad being passed through.

When the WinTV-Quad is passed through to a Windows VM, the Hauppauge WinTV software detects all channels, but tvheadend doesn't detect 2 channels (one channel SNR 35dB, Signal Strength -22dBm and the other channel SNR 25db, -45dBm)

Does tvheadend (or maybe the v4l stack) need to reduce it's thresholds?

I have also had this issue with other devices where it tunes fine in Windows but tvheadend doesn't get all channels...

In the end it was the auto scan not picking up some channels. For the problem muxes I entered some of the details manually and it picked up the channels next scan. Probably also had some issues with cabling and still do but mainly it was the autostart.
