The bug still persists in the 3.6.2 kernel - I can only choose Analog 4.0 Surround Output from the system sound menu in the top panel (front center and LFE speakers are not recognized).
I will run apport-collect once I uninstall the upstream kernel as it needs the one from quantal repository.
Thank you for your advice, Christopher M. Penalver.
I have tried kernel version 3.6.2-030602. 201210121823 (amd64) from http:// kernel. ubuntu. com/~kernel- ppa/mainline/ v3.6.2- quantal/ running on Ubuntu 12.10. Version 3.7-rc1 from http:// kernel. ubuntu. com/~kernel- ppa/mainline/ v3.7-rc1- quantal/ is not installable for me because of the missing *_all.deb package.
