no pcm sound. (flash games etc) - solved

[sparky64]

I have no sound from pcm using audolgy2 sound-card. On-board sound is disabled in bios.
This only started after i added backports and the kernel was updated.
Version.
Linux home 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010 x86_64 GNU/Linux

I can get sound by "sudo alsa force-reload" which lets me watch flash etc.
This throws up another problem in that i can't log/out shut down, I get the shutdown music but thats it.
To shut down i have to ctrl-alt f1 and shutdown from there.

Thanks in advance.

Edit.
Tried out a few things.
cat /proc/asound/modules
gives 1 snd_ca0106

lspci -v | less
gives

Trying to start alsamixer gives this
cannot open mixer: No such file or directory
trying the gui version gives this
alsamixer:function snd_ctl_open failed for default:no such directory.
Kernel modules: snd-hda-intel

Sound is working as i am listening to paradise radio via amarok . It just no pcm sounds.
When i force reload alsamixer will start and shows my card as the correct one.And can listen to flash videos/vlc/games etc.But still can't shut down when i do this.

Re: no pcm sound. (flash games etc)

No help I'm afraid.
Problem is when i get alsamixer to load everything works, Its just not loading on boot.
I Have noticed a couple of problems with audoligy cards/same problem on the forums and the ubuntu forums.
I have disabled on board sound but my g/card has hdmi output and is picked up as a sound source.
I also have a tv card which is also picked up as a sound decoder.
I have also tried a live beta2 and rc and it worked fine, It was only after adding backports - proposed updates. that it stopped working.

This is my alsa-base.conf

Re: no pcm sound. (flash games etc - solved)

Looks like i have sorted it.
I tried the alsa upgrade script i found on the ubuntu forums but could not connect to the alsa site to download the latest alsa-base etc (1/2 gig download wasted in dependencies)
so i added deb http://ppa.launchpad.net/ubuntu-audio-dev/ppa/ubuntu for latest stable. no change.
i now use deb http://ppa.launchpad.net/ricotz/unstable/ubuntu lucid main
Quick reboot and everything seems to work fine. including shutdown/logout problem.
