How to get a sound on Aureon 7.1 Firewire
Generally, follow the instruction on Compiling from SVN page. Here are some comments and the version numbers i noted during my third try.
1. libraw1394 Checked out revision 167.
2. libiec61883 Checked out revision 73.
3. libavc1394 Checked out revision 76.
4. libfreebob Checked out revision 308.
Do the discover test. Why? Because, if the device is not discovered, it won't play. It happened to me during my first try. When i tried to use te Aureon with VIA EPIA EN12000 (onboard FW controller), it was a painfully long story until i tried differenf FW controller which finally worked (the EPIA EN12000 fw controller is recognized by the kernel, modules are loaded, but... the Aureon is not detected). Right now i am using Kouwell controller and it works. Here's a lspci -v on that:
00:0e.0 FireWire (IEEE 1394): VIA Technologies, Inc. IEEE 1394 Host Controller (rev 46) (prog-if 10 [OHCI])
Subsystem: Unknown device 8d14:f7c2
Flags: bus master, stepping, medium devsel, latency 32, IRQ 185
Memory at e1000000 (32-bit, non-prefetchable) [size=2K]
I/O ports at b000 [size=128]
Capabilities: <access denied>
Well, it is aparently VIA chipset, but this one works... sigh...
So, here is the right discovery output:

Wow! Now play something on it! (look at the "Using" page)
Bad luck trying precompiled Debian mplayer:
1: jackd output
JACK protocol mismatch (15 vs 16) cannot complete client connection process
2: mplayer output (excerpt)
========================================================================== Opening audio decoder: [mp3lib] MPEG layer-2, layer-3 AUDIO: 44100 Hz, 2 ch, s16le, 192.0 kbit/13.61% (ratio: 24000->176400) Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3) ========================================================================== client linked with incompatible libjack version. could not attach to JACK server [JACK] cannot open server Could not open/initialize audio device -> no sound.

That means that it was compiled against older version of libfreebob, so i need to recompile it.
Ok, it is too late (or too early :-) today for compiling mplayer, so i tried to compile kluppe (one of jack-output compatible applications). After compilation, the kluppe is playing.
Rerun the jackd with verbose (-v) option gives this (kluppe connects to jackd):
new client: kluppe1, id = 2 type 2 @ 0xa7f73000 fd = 9 ++ jack_rechain_graph(): client freebob_pcm: internal client, execution_order=0. client kluppe1: start_fd=5, execution_order=0. client kluppe1: wait_fd=6, execution_order=1 (last client). -- jack_rechain_graph() registered port kluppe1:main_out_L, offset = 12288 registered port kluppe1:main_out_R, offset = 16384 connect kluppe1:main_out_L and freebob_pcm:dev1p_MultiChannel Front left (output) ++ jack_rechain_graph(): client freebob_pcm: internal client, execution_order=0. client kluppe1: start_fd=5, execution_order=0. client kluppe1: wait_fd=6, execution_order=1 (last client). -- jack_rechain_graph() connect kluppe1:main_out_R and freebob_pcm:dev1p_MultiChannel Front right (output) ++ jack_rechain_graph(): client freebob_pcm: internal client, execution_order=0. client kluppe1: start_fd=5, execution_order=0. client kluppe1: wait_fd=6, execution_order=1 (last client). -- jack_rechain_graph()
and after playback starts:

Wow, it plays!
But...
1. it plays well when there is no load on the machine only. How to make it better?
2. is it stable enough?
I will try to cover the the point 1 first (maybe next week...)
