How do I troubleshoot S-Video + audio jack output not working?
I connect my laptop to my TV using S-Video + audio jack. This worked perfectly in Ubuntu 10.10 but has stopped working in Ubuntu 11.04. I have tried switching from Ubuntu (Unity) to Ubuntu (No effects) and Ubuntu Classic, but it still doesn't work.
Ubuntu recognises that a second monitor is attached and picks the correct resolution. The TV screen remains blue as though there is no signal. The audio doesn't come through either. I have checked the cables are plugged in correctly, and the connection into the TV works (replacing the laptop with a DVD player works).
I am using an Intel graphics card, not NVIDIA.
Any suggestions on further troubleshooting steps?
