As stated in the title, the sound of my Ubuntu 12.04 only works at the login screen and in the Xfce desktop environment.
I have no clue what to do. I have already installed the correct drivers!
$ lshw description: Multimedia audio controller product: 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller vendor: Intel Corporation physical id: 1f.5 bus info: pci@0000:00:1f.5 version: 01 width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list configuration: driver=snd_intel8x0 latency=0 resources: irq:17 ioport:b800(size=256) ioport:bc40(size=64) memory:f4fff800-f4fff9ff memory:f4fff400-f4fff4ff
How do I resolve the issue?
