Jackd doesnt start on ARM Beagle board clone IGEPv2

forgot to add the jack verbose output

Same problem here with origina BeagleBoard rev C2.

I've downloaded an image of Lucid from here:
http://elinux.org/BeagleBoardUbuntu#Lucid_10.04.1

and running jackd with the options in the bug description (i.e. jackd -d alsa -p 256 -n 4 -P hw:0 -S -r 48000) works well.

I've noticed that for enabling sound output in in Lucid you have to set the volumes relative to DAC1 (and Headset obviously) BUT in Maverick you have to adjust the DAC2 controls (because adjusting DAC1 control produces no effects).

Could this be related to jackd not starting in Maverick?

Attached some more debug info in one file (uname + package versions + strace + ltrace)

maybe it is because in maverick, the jack used is JACK2... i think JACK1 is available on maverick. i dont have time to test it right now, but i will check it in the future

Thanks Ricardo. I've replaced jackd2 with jackd1 package.
Now jackd starts ok with command "jackd -m -d alsa -p 256 -n 4 -P hw:0 -r -S 48000" but when I start fluidsynth I get this error on jackd log:

subgraph starting at fluidsynth timed out (subgraph_wait_fd=9, status = 0, state = Triggered, pollret = 0 revents = 0x0)

and fluidsynth seems to start but whenever I try to play a midifile it will not play anything because it's unable to allocate synthesis processes.

Starting jackd in non-realtime mode (jackd -r -m -d alsa -p 256 -n 4 -P hw:0 -r 48000) allows fluidsynth to connect, but then when I play some midifile I only get mono sound on the right channel! (note that this is not a mixer/muting issue because when playing a wav with aplay without jackd I get stero sound. Moreover everything works well in Lucid).

For the moment I will stay with Lucid, but can someone with more experience than me with jackd/fluidsynth on the Beagle post a working example for Maverick or give some suggestions on how I can help to debug the problem?

Btw, this is what works for me in Lucid.
jackd -m -d alsa -p 256 -n 4 -P hw:0 -S -r 48000
fluidsynth -a jack -r 48000 -c 16 -C 0 -R 0 -m alsa_seq -z 64 -j -l -o synth.polyphony=16 Unison.sf2
