Bug Description
First thing to know is that i just made a new install of jaunty (final release) and not a simple upgrade from hardy.
Under Hardy, my sound worked well. I used the same parameters in jaunty, but the sound still sizzles (don't know if the translation is good). System sound are played, but it's crackled. I didn't play mp3 for now, but i guess the results will be the same. I tried different parameters, and still having problem.
the card is known as "nVidia Corporation MCP67 High Definition Audio (rev a1)" under lspci.
Also tried to do an alsa-utils reset (not working, "no valid card number"), the method with module assistant (neither) and finally installed linux-backports
Thanks for spending time in reading/solving.
I have the same issue on this audio chipset. Currently running a fully updated Jaunty (fresh install).
