Update : tried using the GA version of the Live CD - sound came forth quite happily.
In my case I have a system that has been updated from Breezy - Dapper - Edgy - Feisty .... I ownder if this has something to do with the problem. Has everyone else been through updates similarly ? Just a thought in the process of tracking it down. Also, the modprobe did not fix my problem either. malc -- last feisty update breaks sound: SB450 HDA Audio https://bugs.launchpad.net/bugs/88570 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
