I figured out Inspiron 6400 fc5

My setup:

  • Inspiron 6400 (Intel HDA card)
  • fc5 stock kernel
  • Ardour2 from svn
  • jack from svn
  • qjackctl from svn

When I started, I could not get low latency and had many xruns.

After consulting the web (and a particularly helpful friend), here is what finally fixed the problems:

  1. start snd-hda-intel from modprobe.conf with the following sequence:

alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0 position_fix=1

This signifies that there is no position fix

  1. Without the position_fix argument, the “auto” option is implied

  2. I didn’t try the other options found through /sbin/modinfo snd-hda-intel (because I didn’t understand what they meant and I was too lazy to find out).

Boy, Ardour2 is a nice looking project, Kudos!
