OSMC DVB-T2 problem detecting muxes

#1

Hi,
I just bought latest osmc usb dvb-t2 dongle and I have some issues running it on raspberry pi 3. When I run w_scan after reboot muxes are detected correctly. But when I try it second time I not able to detect any muxes and dmesg is full of errors

i2c i2c-3: cxd2841er: i2c wr failed=-11 addr=6c reg=00 len=1
[  249.431762] i2c i2c-3: cxd2841er: i2c wr failed=-11 addr=6c reg=43 len=1

there is part of log where device is registered

I’m running latest stable version of OSMC.

Hard to tell without full logs, but are you running TVheadend?

#3

I tried it with w_scan because I had no luck with tvheadend.

But later I tried dongle on fresh installation of osmc and I was able to tune all muxes correctly. So it seems as issue with my osmc setup.

Thanks for reply

I’m glad things are working now
Were you on a really old version?
