Dump audio from video, revisited

From some post on some mailing list:

mencoder -v -ovc copy -oac mp3lame -o out.avi INPUT-FILE -ss HH:MM:SS
mplayer -v -vo null -vc dummy -ao pcm -dumpaudio -dumpfile out.mp3 out.avi

Analog Devices AD1984A (snd-hda-intel) on HP 6730s, Arch Linux

Here’s a great table for all your snd-hda-intel needs: Ubuntu Wiki audio_intel_da.

Arch Linux: no sound from speakers, headphones OK

As noted here, you must tell the system that you’re using a laptop, so there are several outputs. Edit /etc/modprobe.d/50-sound.conf (or similar) like this:

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel

options snd-hda-intel model=hp

EDIT: for more models and options, see this Ubuntu Wiki page.
