Public bug reported: Hi;
About two days ago I upgraded from Ubutnu 8.10 to Ubuntu 9.04. In the process I lost all audio. I don't know much about the guts of Linux so any help I can get to get audio back would be greatly appreciated. Here is a part of my output that looks audio related from the lspci command: =================================================================== 00:1f.3 SMBus: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) SMBus Controller (rev 02) 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 02) 02:00.0 Multimedia audio controller: Creative Labs SB Live!
