New Ubuntu installation with a big problem: no sound.
OS: Ubuntu 10.4.1
Hardware: HP Pavilion Elite e9150t (64 bit)
Sound card: Creative Sound Blaster X-Fi Xtreme Audio
Preliminary checks of sound level settings and obvious dumb stuff but there is still no sound.
The problem seems to be that the system does not recognize the existence of the sound card and insists on using alternative audio devices.
1. Output of lspci
04:00.0 PCI bridge: Creative Labs [SB X-Fi Xtreme Audio] CA0110-IBG PCI to PCIe Bridge
05:00.0 Audio device: Creative Labs [SB X-Fi Xtreme Audio] CA0110-IBG
08:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT 220] (rev a2)
08:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1)
2. Listing of 'cat /proc/asound/cards'
0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfbefc000 irq 16
1 [Generic ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0xf9ffc000 irq 17
The above is also what shows up in the F6 selection in 'alsamixer'.
I found enough to probably isolate my problem but have absolutely no idea how to fix it.
Help would be greatly appreciated.
