ivtv-firmware has no installation candidate
If when trying to install the firmware, you encounter an error similar to:
supermario@portablemario:~$ sudo apt-get install ivtv-firmware Reading package lists... Done Building dependency tree Reading state information... Done Package ivtv-firmware is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package ivtv-firmware has no installation candidate
This likely means you had a typo when adding the firmware repository to your /etc/apt/sources.list
Recheck /etc/apt/sources.list
and make sure that you properly added the repository that you are getting your firmware from.
unable to open firmware
If you have properly installed the ivtv-firmware package, you will have the firmware in /lib/firmware
$ ls /lib/firmware/v4l*fw -l -rw-r--r-- 1 root root 262144 2006-12-18 14:58 /lib/firmware/v4l-cx2341x-dec.fw -rw-r--r-- 1 root root 262144 2006-12-18 14:58 /lib/firmware/v4l-cx2341x-enc.fw -rw-r--r-- 1 root root 16382 2006-12-18 14:58 /lib/firmware/v4l-cx25840.fw
If you are still encountering errors in dmesg similar to this:
[17179588.876000] ivtv0: unable to open firmware v4l-cx2341x-enc.fw [17179588.876000] ivtv0: did you put the firmware in the hotplug firmware directory? [17179588.876000] ivtv0 warning: failed loading encoder firmware [17179588.876000] ivtv0 warning: Error loading firmware -3! [17179588.876000] ivtv0: Error -3 initializing firmware. [17179588.876000] ivtv0: Error -12 on initialization [17179588.876000] ivtv: probe of 0000:02:08.0 failed with error -12
You should try cold-booting the machine. This involves shutting the machine down, and REMOVING power from the machine. This forces the firmware to be cleared from the memory on the Hauppauge card. A warm boot won't necessarily do this.
After powering down, unplug the power cord from your computer and hold the power button down for 3-5 seconds. This will fully discharge power from your system. Plug in and boot.
