Welp, pretty much as the topic says.
I just noticed today that sound is no longer playing from the internal
speakers of my laptop, a 2010 model Sony Vaio Z. Plugging in headphones
causes sound to be played fine through those. There are three possible
choices for 'Connector' - 'Analog Speakers', 'Analog Output', and
'Analog Headphones' - but none of these seems to make sound come out of
the internal speakers. The default is 'Analog Speakers', and when it's
set to this, headphone output does work when headphones are plugged in.
I've verified that it's broken on Fedora 16 kernels 3.2.6-4, 3.2.8-3 and
3.2.10-1. It's also broken in a very recent Fedora 17 kernel, 3.3.0rc6
or so. It works on a Fedora 16 live image, with kernel 3.1.0-1.
Unfortunately the kernels before 3.2.6 have been trashed from Fedora's
buildsystem archives, I think, so it's hard to narrow things down any
