[linux-audio-user] UBUNTU/DEMUDI

Hi all,

For those who seem to be interested in UBUNTU/DEMUDI,
here are some steps that I resolved and some others where
I'm blocking.
I'm new in Linux/audio.
For a first time with I would like to record my bass with rosegarden and
play drums with hydrogen.
My card : maudio 1010 LT which don't have Synth Support under ALSA
  $kinfocenter
  Synth devices : NOT ENABLED IN CONFIG

>> KERNEL ..... OK
In the file /etc/apt/sources.list, add :
  deb http://demudi.agnula.org/packages/demudi stable main

In a terminal :
  $apt-get update
  $apt-cache search kernel
  $apt-get install kernel-image-2.6.12-2-multimedia-386
  $apt-get install kernel-patch-2.6-realtime-lsm

>> MODULES ..... OK (except virmidi)
In a terminal :
  $lsmod |grep snd

You need to have :
  snd_seq_midi .......... OK
  snd_seq_midi_event .... OK
  snd_seq ............... OK
  snd_rawmidi ........... OK
  snd_timer ............. OK
  snd ................... OK
  soundcore ............. OK
  snd_virmidi
  realtime

If you don't have one, execute "modprobe" in a terminal.
For example :
  $modprobe snd_virmidi
  FATAL: Error inserting snd_virmidi
(/lib/modules/2.6.12-2-multimedia-386/kernel/sound/drivers/snd-virmidi.ko):
  No such device
  It was OK with ubuntu kernel !!!

  $modprobe realtime any=1

>> ALSA
  $apt-cache search alsaconf
  $apt-get install alsa-utils
  Then you have
  $alsaconf
  $alsamixer
  $alsactl

>> JACKD ..... OK
  $apt-cache search jackd
  $apt-get install jackd

>> QJACKCTL ..... OK
  $apt-cache search qjackctl
  $apt-get install qjackctl

Set qjackctl with jackd, not with jackstart
  with jackstart :
  #12:12:42.618 Patchbay deactivated.
  #12:12:42.906 Statistics reset.
  #12:12:42.980 MIDI connection graph change.
  #12:12:43.114 MIDI connection change.
  #12:12:45.920 Startup script...
  #12:12:45.921 artsshell -q terminate
  #12:12:46.252 Startup script terminated with exit status=256.
  #12:12:46.252 JACK is starting...
  #12:12:46.253 /usr/bin/jackstart -R -dalsa -dhw:0 -r48000 -p2048 -n2
  #12:12:46.256 JACK was started with PID=7553 (0x1d81).
  #jackstart: cannot get realtime capabilities, current capabilities are:
  # =ep cap_setpcap-e
  # probably running under a kernel with capabilities disabled,
  # a suitable kernel would have printed something like "=eip"
  #12:12:46.263 JACK was stopped with exit status=1.
  #12:12:48.268 Could not connect to JACK server as client.

>> ... and then I can run HYDROGEN

to use rosegarden, I need
>> QSynth first
>> and then ROSEGARDEN

I import some hydrogen samples in rosegarden, and I don't have any sound.
Does somebody have an idea ???
May be this is the virmidi module which is not loaded ?

Best regards,
Benjamin
