I don't have this option. I also don't have an nforce3 chipset. See also my previous comment that this is a different problem than bug #37055. If I plug external speakers into the headphone jack on the laptop, the internal speakers are muted properly.
But if I plug them into the headphone jack on the */port replicator/* they do not produce sound, and the internal speakers are not muted. -- Dell C510 port replicator headphone jack https://launchpad.net/bugs/37409 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
