Hi,
after having used Ubuntu for about a year now, without problems I couldn't solve myself, I now ran into one where I really need help.

My mainboard is a MSI K9N Neo V2 with the nVidia520 Chipset. I use the onboard soundcard which is a Realtek ALC888 Chip.

Everything worked flawless (starting from 8.04 to 9.10) but about 3 weeks ago I couldn't get any sound from the board after a System Update.

I first thought it would be a bug in the kernel which would be fixed sooner or later, but as I updated again today (to a new kernel) and I still got no sound I decided to seek help from the community.

aplay -l gives me
Code:
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: ALC888 Analog [ALC888 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 1: ALC888 Digital [ALC888 Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
in ->System->Preferences->Sound
I've got the choice between
  • Internal Audio Digital Stereo (IEC958 )
  • Internal Audio

Internal Audio is selected, as I want to use a Headphone.

No, the Volume isn't muted...
and Yes, I tried all 6 available Jacks at the back of my PC

any Ideas that could help me are welcome
Thanks a lot in advance....
