Hi @Sam,
thanks for backporting the relevant drivers in the May update! My DVB stick finally seems to be recognized properly now:

However, we’re not quite there yet as each mux scan fails with the following error:
2017-06-12 11:25:42.011 mpegts: 498MHz - tuning on Silicon Labs Si2168 : DVB-T #0
2017-06-12 11:25:42.011 linuxdvb: Silicon Labs Si2168 : DVB-T #0 - DTV_CLEAR failed [e=Inappropriate ioctl for device]
My educated guess would be that this is due to the platform mismatch between Tvheadend (32 bit) and the kernel driver (64 bit), with a potential patch available. That, however, should affect all drivers so it’s unlikely to be the root cause, right?. I also checked the device file permissions and they’re correct (r/w for group video which user osmc is a member of).
Any idea?
Cheers
