This tool will dump the firmware pin configuration as a plist, and allow you
to upload a patched version (hdafg will detach and reattach using the new

Hi -

with hdaudio, my laptop's (Dell Latitude D820) speaker
is quiet. An external speaker connected to the headphone
jack works.
Where to start debugging?
The dmesg output is:
