I have 12.10 installed on a Thinkpad x230. It works great except for sound. I do have sound in the login page, but after I log in and get to the desktop, everything is perfectly silent.
I went through all the guides, nothing is muted, alsamixer looks ok in the console etc, but no sound plays and no errors are reported that I can see. I tried restarting pulseaudio and alsa but no change.
I installed Ubuntu 10.04 dual booted with Windows 7 on my Lenovo laptop. In windows 7 sound plays fine from speakers and headphones. But in Ubuntu sound only plays through the headphones, not the speakers. I researched and have been troubleshooting with no luck of getting the internal speakers to play.
Installed Mint 15 XFCE on my desktop and none of the sound/output devices work. I have a few to choose from and none of them are working (onboard sound, sound blaster pci card, USB DAC, and HDMI output.)
I booted up to Mint 15 Cinnamon version, and everything works great, all devices can output sound.
I originally had a different motherboard with the usual HD'97 sort of codec onboard and sound worked fine. Then I upgraded my motherboard to a Gigabyte G1.Sniper 3 which has a Creative CA0132 sound chip. I did not reinstall after the upgrage, but everything worked fine, including the sound. Then maybe a month or so back I did system updates and the sound stopped working.
