AV cable and raspberry pi B+

I'm able to taste the latest revision of Raspberry Pi, the model B+ recently. Compared to the previous version this has more advantages,

1) 40 GPIO pins
2) 4 USB ports
3) Neat micro SD slot with push to release capability
4) 3.5mm integrated Audio/video port

We can find tons of information available on-line about first three, but found the last point bit complicated.

If you have a nice HDMI supported monitor or TV no need to worry about this. But if you are going to plug your Raspberry pi B+ to an old fashioned TV with a AV cable this post might helps you :)

Selecting a cable,
This is bit tedious task since there is no standard for AV cable pinouts. Found this post which is really helpful for this task.

FYI : I bought zune AV cable with the correct pinout configuration for Raspberry pi B+.

Even with the correct cable you won't get this to work in first attempt :(

I tried with the NOOBS installation, by default NOOBS configures HDMI output with higher priority than our poor AV out.

You can find this configuration in /boot/config.txt file,

hdmi_force_hotplug=1 config_hdmi_boost=4

 I have commented out above default configuration and added following, with this configuration even if you have a HDMI monitor plugged in it will use the composite output.

hdmi_ignore_hotplug=1
#hdmi_force_hotplug=1
#config_hdmi_boost=4
