I discovered a fix to the problem. Someone somewhere with a virtually identical laptop (the next model year's version) to mine suggested installing the ALSA Kernel backports and it worked perfectly. The sound chipset is unusual enough that it has issues in Windows 7 as well which are about as easily solved (which is to say extremely easy once you've found out how to do it).
For the record I have a Gateway P-6831FX and the next year's model is the P-6860FX which has the next generation chipset, graphics card, but apparently the same audio chip or a functionally identical one. -- sound only through headphones intel audio in Jaunty https://bugs.launchpad.net/bugs/349633 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
