Thanks for that.
Currently I'm just trying to get sound via the HDMI cable - I found a setting that generates sound through the headphone jack but not HDMI - OK for testing on a monitor but not much use for a TV 
Something I did, not sure what but I'd really like to know, seems to have worked and I now have sound from the HDMI cable to the TV.
Found the setting - I now have noise with my film. Just need to sort out freezing whilst recording and watching films now.
Just installed Raspberry Pi OS desktop on another SD card and I do get audio when playing the same film in VLC in that. Is there a hidden setting somewhere I'm missing?
I'm trying to put together a RPi4, Haupagge WinTV-DualHD tuner to replace my current setup of an RPi3 running LibreElec /Kodi and an RPi3 with TVHat running LibreElec & TVHeadend (OK I know KODI is there as well). The idea is to go from two machines to one. I've been having difficulty with v10 of LibreElec some freezing and no audio. I've just downloaded v9.2.8 LibreElec to try. I had v4.3 TVHeadend server and 4.2 client.
Does anyone have suggestions for a known working setup?
ps I'm good with Windows but not Linux so if I need to download / run commands please remember newbie here.
Anyone using this addon on a RPi4?
Just to round the thread off. Yesterday I ordered from PiHut
- RPi4B
- Argon One case
- Power supply
and
- Hauppauge WinTV-dual HD
from Amazon (they seem to have a monopoly.
Thanks for the responses
I tried changing all the bits I had spares for, the connector between the TVHat and the antenna's coax isn't one of those. I've ended up blaming it because I've eliminated (I think) the other options. Things work fine as long as the Pi isn't disturbed so I may source another connector if I don't go down the RPi4 route. If I go that way I'll probably go for a Hauppage dual tuner.
"why that ?" - because it was suggested I start reading the source headers
"your are more on the safer side if you buy elder hardware" - that is a very good point, and one I hadn't really thought about.
"Also the thing with the price is you have to remember you'll probably never need to buy one again, so there's that. 
" - you obviously didn't realise I'm a Yorkshireman living in Scotland so I have a double helping of hating to spend money.
Good point though.
I appreciate that people here are volunteers but whilst I have umpteen years Windows experience I have virtually zero Linux knowledge and I would prefer not to have to learn yet another programming language just to find which bits of hardware are currently supported. On the other hand its possible I may be misunderstanding your recommendation.
Thanks, that give me some useful information. I've had a look on Amazon and my wallet is cringing <G> I also tried contacting Haupagge and was told to ask elsewhere.
Thanks. I already have a TV Hat and I want to replace it since the antenna connection is very sensitive to minor disturbance.
I'm planning on having a Pi dedicated as a "TV server". Is there a list anywhere showing which devices are supported by LibreElec/KODI/TVHeadend? I'm not keen on spending £60 on a Hauppage and finding there isn't a driver.
Thanks - I'll have a look
Currently I have 2 RP3s. Both running LibreElec & Kodi. One is just for viewing films stored on a 6TB USB drive and the other has TVHeadend and a TVHat. The pair ran really well until I installed a laptop cooling fan which needed me to move the RPis. Ultimately I trace the trouble I was having with recording on the sensitivity of the connection to the TVHat PCB - the smallest nudge can cause signal loss which requires much messing before recording again works.
I've found this (DVB-T2 USB Devices - LinuxTVWiki) but its 6 years old and I know the Hauppauge line will work with RPi just wondering if there are any others that people would recommend.
It looks like a very useful utility and I'll install it, but I'm not sure how it helps with Clonzilla.
For now I've decided to create an image and then write the image back to another micro sd - takes a bit (!) longer but it works.
I'm having to reinstall LibreElec & TVHeadend on an RPi3 (TVHeadend went weird and decided not to end recordings) - no problem. I decided that to make life easier for myself I'd create a clone of the Micro SD card so if it happened again it would be a simple swap. I'm using 64GB Micro SD cards because recordings get stored on there as well (I had a lot of problems when I tried to use an SSD in a USB slot).
Long story shortened: I ended up thinking to use a live Clonezilla USB stick in my laptop running Linux Mint. This laptop has 64GB disk so I have 3 64GB disks and a 32GB disk to choose from. How, with the cryptic identification Clonezilla gives each how can I select the source & target from the three possibles (I can thankfully eliminate the 32GB memory stick).
I'm thinking of changing my current RPi3B & Kodi plus a RPi3B & TVHat & TVHeadend to a single RPi4. Its very difficult to identify which of the cases with fans have the room to fit a tvhat and have the antenna connector sticking out. Any suggestions?
