No Sound in Ubuntu 10.04 Lucid Lynx

[smythie86]

I get no sound for anything, I am running Ubuntu Lucid-amd64. Pulseaudio detects my sound card, and appears to be playing to it when I look at pavucontrol. But I get no sound for anything, not even alerts. I don't eve know how to debug it, because everything I have looked at looks like it should be working. I have checked every mute button I can find, and nothing is muted that I can see. The relevant information for my sound card from lspci -v is:

07:00.0 Multimedia audio controller: Creative Labs CA0106 Soundblaster
Subsystem: Creative Labs Device 100a
Flags: bus master, medium devsel, latency 32, IRQ 21
I/O ports at 1000 [size=32]
Capabilities: <access denied>
Kernel driver in use: CA0106
Kernel modules: snd-ca0106

Does anyone have any idea what could be wrong?

Thanks in advance!

Was this an upgrade or clean install? Is this an add-on card? Can you post the output of these terminal commands for me please:

uname -a
aplay -l
cat /proc/asound/version
head -n 1 /proc/asound/card*/codec#*

Terminal="Applications->Accessories->Terminal"
Please post text output using code tags. Also helpful is the make/model of your PC/Laptop.

Just wanted to thank you, I was having the same problem with my sound, found this thread via google and your fix worked great.
