I had the misfortune of purchasing two of these PCIe TV tuners (as per lsusb):<\/p>\n

Bus 004 Device 002: ID 1f4d:a803 G-Tek Electronics Group\r\nBus 003 Device 002: ID 1f4d:a803 G-Tek Electronics Group<\/pre>\n
I’d assumed that the RTL2832U was a common chipset, and would detect on a stock kernel. How wrong I was. Not only do you need to compile media_build, you need to patch <\/em>media_build for this card to detect.
\n<\/p>\n
I originally found a patch for 3.8 kernel on the web. It seems I can’t find it on the web any more, and the kernel has changed slightly since then. I had to change how an enum was referenced to get it working in Linux 4.2.<\/p>\n
Update 22nd<\/sup> Feb 2017: I had to update the patch to work on a 4.8 kernel. The 4.2 patch can still be found here<\/a>.<\/p>\n
Here’s the original instructions <\/a>I found on the net (copy\/pasted here).<\/p>\n
sudo apt install build-essential \r\nsudo apt install linux-headers-`uname-r`\r\nsudo apt install libproc-processtable-perl\r\nmkdir dvb-2832u\r\ncd dvb-2832u\r\ngit clone git:\/\/linuxtv.org\/media_build.git\r\ncd media_build\r\n.\/build\r\ncd linux\/\r\npatch -p1 < ..\/dvb-usb-rtl2832.patch<\/a>\r\ncd ..\r\nmake allmodconfig\r\nmake\r\nsudo make install<\/pre>\n
It’s a bit of a pain when a kernel update comes through. After rebooting to the new kernel, you need to edit the following file and update the version number to the currently running kernel:<\/p>\n
.\/v4l\/.version<\/pre>\n
Then rebuild and install:<\/p>\n
make\r\nsudo make install<\/pre>\n
…and reboot.<\/p>\n","protected":false},"excerpt":{"rendered":"
