What HW/SW do people have working?

Couple of questions:
- I was under the impression that to get rt kernel in 8.10 the kernel had
to be compiled locally.
- do you have any comparison between the freebob drivers and the ffado. (I
realize the later are the new generation, do they improve life with
- have you attempted to use more than one audiofire12? (i.e. two = 24

I have a little Dell XPS 1210 which I recently got working for my modest
studio. All the details were in this post to the FFADO list:
Here it is in all its posterity:
Well, I got it all working. I wanted to share my progress with everyone by
the wiki but I don't have access to that. Here's what I did (in a
Dell XPS M1210 laptop
Intel T5600 1.8GHz Core2Duo
Intel 945GM Video controller
Sigmatel 9220 internal audio controller
Internal Ricoh Co Ltd R5C832 IEEE 1394 Controller
Ubuntu Studio 8.10 with RT (realtime) kernel
1. Install UbuntuStudio 8.10.
2. Install all updates via update manager
3. Install RT kernel
~$ sudo apt-get install linux-rt
4. Install ffado drivers and accompanying libraries
In Synaptic Package Manager choose Settings/Repositories. In the Software
Sources window choose the Third-Party Software tab. Add the following:
deb http://www.ffado.org/apt gutsy contrib
Reload your package manager and install the following:
libffado2-dev (just in case)
5. Configure grub to boot RT kernel by default
~$ sudo vim /boot/grub/menu.lst
edit the line:
or whatever number (counting from 0) is your rt entry in the file. If you
don't do this you have to manually choose it at boot every time.
6. Add yourself to the disk and audio groups. If the audio group
exist you can create it with the optional first command.
~$ sudo groupadd audio (optional step if audio group doesn't exist)
~$ sudo adduser <username> disk
~$ sudo adduser <username> audio
7. Adjust limits.conf to accommodate your RT kernel.
~$ sudo su -c 'echo @audio - rtprio 99 >> /etc/security/limits.conf'
~$ sudo su -c 'echo @audio - nice -19 >> /etc/security/limits.conf'
~$ sudo su -c 'echo @audio - memlock unlimited >>
8. Reboot to your RT kernel!
After you system is up and running you'll have to start jackd. I recommend
qjackctl to do this as it has a patchbay manager. Make sure everything is
and running then start qjackctl (found in Sound & Video/Audio
9. You must install the raw1394 kernel module. Unfortunately my ability
to get this
to stick hasn't worked. No problem, just run the following short
~$ sudo modprobe raw1394
10. Here are the changes I made to the default jackd config by clicking
Driver = firewire
Priority = 70
Frames/Period = 64
Sample Rate = 48000
Periods/Buffer = 3
Port Maximum = 128
Interface = hw:0
Start Delay = 2
11. Click the Patchbay button. Click the New button and let it
port configurations itself. Mine showed System with 12 capture
under Output and it showed System with 12 playback ports under
System in both windows and choose Connect. You may have to click
though I don't really know exactly what that does.
Click the start button and pray for no xruns. Following these exact steps
able to successfully record in Ardour for 30ish minutes without xruns or
errors. It may go longer but I haven't bothered trying yet.
The big hurdle I encountered was outdated information on many websites.
First of all,
the Ricoh 1394 controller does not work with 8.04.1 RT kernel. It is
wonderfully with my 8.10 RT kernel. I hope someone can update the page at:
to show that success has been had with the Ricoh R5C832 1394 controller and
reference this guide.
