problem solved by updating from 12.04 to 12.10.
System settings/sound does not open, freezes and I have to force close. Speaker symbol with volume control does not open scroll-down menu, and there is no sounds. Many people have problems with Hudson Azalia in Ubuntu, but I found no working solution.
I don't really understand much of this, but here are some more details:
aplay -l : **** List of PLAYBACK Hardware Devices ****
(after running this one, it starts some kind of process that doesn't get any results, and doesn't stop, terminal has to be shut down)
lspci -vnn | grep -iA5 audio: 00:01.1 Audio device : Advanced Micro Devices [AMD] nee ATI Device [1002:9902] Subsystem: Hewlett-Packard Company Device [103c:184c] Flags: bus master, fast devsel, latency 0, IRQ 53 Memory at f0444000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel -- 00:14.2 Audio device : Advanced Micro Devices [AMD] Hudson Azalia Controller [1022:780d] (rev 01) Subsystem: Hewlett-Packard Company Device [103c:184c] Flags: bus master, slow devsel, latency 32, IRQ 54 Memory at f0440000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel
It seems to me that I'm currently running hda Intel drivers on my AMD Hudson Azalia soundcard. I can't see what drivers this soundcard uses.
Update: I've noticed after some more using, that any program, asked to play a sound of any kind, instantly freezes. also the part of all settings that has anything to do with sound, doesn't exist. aplay -l returns a empty list, my standard vollumecontroll just isn't there, and Rhythmbox and Banshee both freezes on startup!
Ive installed pretty much every pakage I can find in the Software Center that has anything to do with sound, and nothing works! Would really appreciate some help with this!
Update: Ive tried to fresh install the Ubuntu 12.10 Beta 2, hoping it's exstended suport for newer hardware would solve my problems, and it did, kind of. I can now hear the beutifull login-sound! only the screen stays black. Not comand-line black, more, shut-off black. there is nothing. the fan and the small indicatorlight on my power-on button are the only things telling me the computer is at all turned after the login-sound is played on 12.10.
So I went back to 12.04, and this time around, I got an EDD information missing error, and it will only boot from the live cd (or USB-disk in this case), and when I do start it with the live USB, everything conected to sound is missing, once again. When I turn of the computer there is always a message telling me that Gnome-settings-deamon is not responding, and must be force -closed. I find thiss odd, since ubuntu is using Unity by default? (I have not yet installed gnome, as my entire system is cripled) It seems the whole sound-settings part of the system went missing, so I thought it might be something wrong with the live-image I used to create the USB-disk. Dowloaded a new one, installed again, no success. same EDD error, same problem.
Just to try if ANY Linux distro could work on my machine, I installed Fedora 17, works like a charm strait out of the box. only problem is I dont like fedora, I dont understand it, I cant even install applications on it, so I want back to Ubuntu, where I belong. But I cant fix this error.
booting with the arguments edd=on and nolapic and also removing quiet splash, I recieved, among many others, these errors:
'unlink after IRQ...probably using the wrong IRQ'
'PCI INTA -> Link [LNKB]->GSI 11 (level, low) -> IRQ 11'
