I have recently upgraded my HP HDX 9120EA from 9.04 to 9.10 and am seeing the same problem - following the instructions enables sound. I will try removing the model number to see if it is just changing the line jack mode that makes sound work.
Interestingly, I was running Gentoo until a few weeks ago and had similar problems after a kernel upgrade, but never had the time to identify the problem - I just gave up on sound, or used headphones ('cause they still worked). -- [Regression] No sound with Karmic on HP HDX 9300 https://bugs.launchpad.net/bugs/407790 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
