Hi All I'm having significant trouble getting a Saffire LE to work with my setup. I have a Dell XPS M1210, running Ubuntu Studio. Because the inbuilt firewire device is the infamous RICOH chipset, I am forced to use a firewire Expresscard/32, detailed below :~$ lspci -v 0e:00.0 FireWire (IEEE 1394): Texas Instruments XIO2200(A) IEEE-1394a-2000 Controller (PHY/Link) (rev 01) (prog-if 10 [OHCI]) Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 18 Memory at ecc04000 (32-bit, non-prefetchable) [size=2K] Memory at ecc00000 (32-bit, non-prefetchable) [size=16K] Capabilities: [44] Power Management version 2 I am able to configure and start jack, :~$ /usr/bin/jackd -v -R -P89 -dfreebob -dhw:0 -r48000 -p128 -n3 Which produces getting driver descriptor from /usr/lib/jack/jack_dummy.so getting driver descriptor from /usr/lib/jack/jack_oss.so getting driver descriptor from /usr/lib/jack/jack_freebob.so getting driver descriptor from /usr/lib/jack/jack_alsa.so jackd 0.109.2 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. server `default' registered registered builtin port type 32 bit float mono audio registered builtin port type 8 bit raw midi clock source = system clock via clock_gettime loading driver .. new client: freebob_pcm, id = 1 type 1 @ 0x806ff40 fd = -1 Freebob using Firewire port 0, node -1 new buffer size 1024 LibFreeBoB MSG: FreeBoB Streaming Device Init LibFreeBoB MSG: Using FreeBoB lib version libfreebob 1.0.7 LibFreeBoB MSG: Device information: LibFreeBoB MSG: Device options: LibFreeBoB MSG: Port : 0 LibFreeBoB MSG: Device Node Id : -1 LibFreeBoB MSG: Samplerate : 48000 LibFreeBoB MSG: Period Size : 1024 LibFreeBoB MSG: Nb Buffers : 3 LibFreeBoB MSG: Directions : 0 showDevice: not implemented FreeBoB MSG: Register MIDI IN port dev1c_Midi In FreeBoB MSG: Register MIDI OUT port dev1p_Midi Out FreeBoB MSG: Streaming thread running with Realtime scheduling, priority 14 FreeBoB MSG: Registering audio capture port C0_dev1c_Rec 1 FreeBoB MSG: Registering audio capture port C1_dev1c_Rec 2 FreeBoB MSG: Registering audio capture port C2_dev1c_Rec 3 FreeBoB MSG: Registering audio capture port C3_dev1c_Rec 4 FreeBoB MSG: Registering audio capture port C4_dev1c_Rec 5 FreeBoB MSG: Registering audio capture port C5_dev1c_Rec 6 registered port system:capture_1, offset = 4096 registered port system:capture_2, offset = 8192 registered port system:capture_3, offset = 12288 registered port system:capture_4, offset = 16384 registered port system:capture_5, offset = 20480 registered port system:capture_6, offset = 24576 FreeBoB MSG: Don't register capture port for dev1c_Midi In FreeBoB MSG: Registering playback audio port P0_dev1p_Play 1 FreeBoB MSG: Registering playback audio port P1_dev1p_Play 2 FreeBoB MSG: Registering playback audio port P2_dev1p_Play 3 FreeBoB MSG: Registering playback audio port P3_dev1p_Play 4 FreeBoB MSG: Registering playback audio port P4_dev1p_Play 5 FreeBoB MSG: Registering playback audio port P5_dev1p_Play 6 FreeBoB MSG: Registering playback audio port P6_dev1p_Play 7 FreeBoB MSG: Registering playback audio port P7_dev1p_Play 8 FreeBoB MSG: Don't register playback port dev1p_Midi Out registered port system:playback_1, offset = 0 registered port system:playback_2, offset = 0 registered port system:playback_3, offset = 0 registered port system:playback_4, offset = 0 registered port system:playback_5, offset = 0 registered port system:playback_6, offset = 0 registered port system:playback_7, offset = 0 registered port system:playback_8, offset = 0 ++ jack_rechain_graph(): client freebob_pcm: internal client, execution_order=0. -- jack_rechain_graph() FreeBoB MSG: MIDI threads running with Realtime scheduling, priority 13 FreeBoB MSG: MIDI queue thread started libiec61883 warning: Established connection on channel 0.
