Since my reboot=pci post seems to have helped a few people out, I
thought I'd further note another recent fix for Z1* users: sound from
the internal speakers (and mic in) is working again in kernels since
3.12 RC1. See the thread "No sound with Sony VAIO VPCZ1 (ALC889)" on
alsa-devel mailing list. It looks like the old Z's unusual
noise-cancellation feature rather confused things for a while: the
'headphone out' jack is really a headset jack with a mic-in channel as
well as headphone-out (the idea being the system can use the input from
the mics on the sides of the earphones for doing noise cancellation),
and no-one on the kernel/PA side knew what to do with it. In 3.12 the
input channels still aren't quite perfect, but at least speaker and
headphone output both work.
