I had the same problem with this upgrade and an ICH6. Alsamixer and 'm' for unmute fixed it. The mute state is not at all obvious; I would guess its starting value/default changed?

[Gilbert Wolf (famille-wolf)]

Fine it works :-)
Yes default values have certainly been changed, now I'll try to save these new configuration.
Many thanks
