0x104d8144 needs AC97_TUNE_INV_EAPD

[Katie]

Using Ubuntu 9.10.

alsa-base 1.0.20+dfsg-1ubuntu5

Sound worked fine in Jaunty, but since upgrading to Karmic I haven't heard a peep from any application. I checked that the volume is not muted or low.

Please mute 'Line Jack Sense' using the following command in a Terminal:
amixer set 'Line Jack Sense' mute

If sound remains inaudible, please also try muting 'External Amplifier':
amixer set 'External Amplifier' mute

That fixed it, thank you so much! Specifically, although it didn't work after muting 'Line Jack Sense' alone, it did work after muting 'External Amplifier'.
