 | Hey Marcos,Big props for Musix, bloody excellent work!

Thanks, I am fowarding this email to the development mailing list and 
to the spanish language users, the crew and friends will be delighted 
(i hope my english would be good enought to express my ideas :S )

What kind of work? I am really interested.

I can see 

install ok installed libfreebob0

And, asking help to the jackd app, I tells us:

       jackd -d backend --help

So "-d backend [ ... backend args ... ]
             The backend can be `alsa', `coreaudio', `dummy',
                                `freebob', `oss' or `portaudio'."

Did you tried -dfreebob ?

Then I see

 /usr/bin/jackd -R -p128 -t2000 -m -d 
freebob -dhw:0 -r48000 -p512 -n2 -s
Unknownage with option 's'
Options for driver 'freebob':
        -d, --device    The FireWire device to use. Format 
is: 'hw:port[,node]'. (default: hw:0)
        -p, --period    Frames per period (default: 1024)
        -n, --nperiods  Number of periods of playback latency 
(default: 3)
        -r, --rate      Sample rate (default: 48000)
        -C, --capture   Provide capture ports. (default: false)
        -P, --playback  Provide playback ports. (default: false)
        -D, --duplex    Provide both capture and playback ports.

        -I, --input-latency     Extra input latency (frames) (default: 
0)
        -O, --output-latency    Extra output latency (frames) 
(default: 0)
        -i, --inchannels        Number of input channels to provide 
(note: currently ignored) (default: 0)
        -o, --outchannels       Number of output channels to provide 
(note: currently ignored) (default: 0)

Here it fails, maybe bacause I dont have such devices:

/usr/bin/jackd -R -p128 -t2000 -m -d freebob -dhw:0
