I have no sound since installing Ubuntu 11.10 on my Dell Vostro 3400. It looks like the HDMI sound card is found, but not the card that would make sound come out of my speakers.
This is what appears to be the relevant output from lshw:
*-multimedia UNCLAIMED description: Audio device product: 5 Series/3400 Series Chipset High Definition Audio vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 06 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress cap_list configuration: latency=0 resources: memory:fbe00000-fbe03fff
It is funny as the sound "just worked" with Fedora 13-15, but not with Ubuntu 11.10 out of the box.
Any help would be greatly appreciated.
