WinTV DualHD not working after sleep/wake

Hi there,

I'm new to LibreELEC and TVHeadEnd so please be gentle!

I have an x64 PC running LibreELEC with a USB Hauppauge WinTV-dualHD tuner. I had to update to a milhouse 9.0 build in order to get both tuners working but it is all configured now and live TV works well. Now I have a problem where the TVHeadEnd RTSP Client reports "no signal" after the system resumes from sleep.

I have seen some posts from folks with the same problem and the solution seems to be to reload some modules when the system resumes. Please could someone help me find out what exactly I need to do to get this working for my particular setup?

Here is the URL generated when I did lsmod | paste via SSH:

try

Code

em28xx_rc em28xx_dvb em28xx

lsmod | paste <- keep

unload

systemctl stop service.tvheadend42

modprobe -r em28xx_rc

modprobe -r em28xx_dvb

modprobe -r em28xx

this should work without any errors, if so your device should be unloaded correctly

check with lsmod | paste (maybe post here)

load again

modprobe em28xx

modprobe em28xx_dvb

modprobe em28xx_rc

systemctl start service.tvheadend42

check with lsmod | paste and compare it with the first lsmod before the unload process - they have to be identical

Difficult to do from remote because if you unload em28xx_rc it maybe unloads automatically em28xx_dvb or vice versa, after you hit some error pls do an reboot to create an clean setup again.

OK, I think I follow!

After running the unload commands I get this:

(em28xx, em28xx_rc and em28xx_dvb are gone)

And after running the load again commands I get this:

http://ix.io/1hey

(all back again, and TV playback works)

Is the next step to paste these commands in to some config files (one to run as the system is going to sleep, one to run as it wakes up)?

Thanks for taking the time to look at this, I really appreciate it!

like said it has to work with the procedure above

btw rc_hauppauge si2157 si2168 are DVB related modules - might be needed to add them too

I just added the three em28xx ones and tested sleep and then wake - and TV still works!!

I will see how things go over the next day or so, but noted re: the other modules.

Great work, thanks again!
