No sound from External Speakers
I'm using fedora core 2 with a recompiled 2.6.6 kernel on an HP ZX5000. Sound card is ati ixp150. Sound is fine from the built-in laptop speakers, but there is no sound when I connect my external speakers on the headphone jack. Works fine in windows, so its not a hardware problem. I think it may be a mixer setting, but I haven't been able to make it work after fiddling for long.
HOWever, the headphone setting in alsamixer is "Off"; if that is the problem, how can I switch it on.
