[gentoo-user] My Rosegarden Woes

[Michael Sullivan]

I emerged rosegarden the other day.  When it starts up it tells me that
the MIDI sequencer could not be started.  I've been working with the
rosegarden-user mailing list to work through this problem.  They had me
send them some debug information and now they tell me that the problem
is with my snd-seq-midi module.  I use alsa-driver because I couldn't
get my sound card to work with alsa compiled into the kernel.  They've
never heard of alsa-driver.  They recommended that I take this new
development to you.  How can I get alsa-driver to give me a working
snd-seq-midi module?  My /etc/modules.d/alsa is thus:

camille ~ # cat /etc/modules.d/alsa
#------------------------------
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

# Set this to the correct number of cards.
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF version 1.0.10rc2 ---
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
# --- END: Generated by ALSACONF, do not edit. ---

options snd-hda-intel model=3stack position_fix=2
#-------------------------------

I'll be happy to send any other information you need to help me solve
this problem...

I've been lurking on that list as well... I have everything working, but I'm not sure about your problem. I have everything alsa compiled in my kernel. However, I think there's a package for the alsa oss stuff... have you installed that as well? I believe those modules only get loaded via modules.d/alsa when they are present.

* media-libs/alsa-oss
     Available versions:  1.0.8-r1 ~1.0.9 1.0.10_rc2 1.0.10_rc3 ~1.0.10
     Installed:           none
     Homepage:            http://www.alsa-project.org/
     Description:         Advanced Linux Sound Architecture OSS compatibility layer.

Do you have this installed? Again, just a guess.

HTH.

I didn't have it installed.  Now I do:

*  media-libs/alsa-oss
      Latest version available: 1.0.10-r1
      Latest version installed: 1.0.10-r1
      Size of downloaded files: 218 kB

layer.

I restarted alsasound and attempted to start rosegarden and the MIDI
sequencer still failed....

Um... again, I'm not a guru. I went through many days of pain to have a system working. It was working well yesterday. I'll see about today... '-) Yep. Still functions well.

lsmod |grep snd
snd_virmidi             4096  0
snd_seq_virmidi         8128  1 snd_virmidi

(... I installed this, but I'm pretty sure it has nothing to do with anything yet.)

Since I don't know what your specific issue is, I'll throw a bunch of stuff out... maybe it'll trigger an idea for you to explore.

ls /dev|grep midi
admmidi
admmidi2
amidi
amidi2
dmmidi
dmmidi1
dmmidi2
midi
midi0
midi00
midi01
midi02
midi03
midi1
midi2
midi3
rmidi0
rmidi1
rmidi2
rmidi3

ls /dev|grep seq
sequencer
sequencer2

sudo cat /var/lib/portage/world |sort|grep alsa
media-libs/alsa-lib
media-plugins/alsa-jack
media-sound/alsa-headers
media-sound/alsa-tools
media-sound/alsa-utils
media-sound/gnome-alsamixer

sudo cat /var/lib/portage/world |sort|grep synth
media-sound/amsynth
media-sound/fluidsynth
media-sound/qsynth

sudo cat /var/lib/portage/world |sort|grep midi
media-sound/qmidiarp
media-sound/timidity++
media-sound/timidity-eawpatches
media-sound/timidity-shompatches

media-plugins/alsa-jack
media-sound/jack-audio-connection-kit
media-sound/jack-rack
media-sound/qjackconnect
media-sound/qjackctl

#!/bin/sh
/usr/bin/jackd -R -P 99 -d alsa -d hw:1 -r 48000 -p 1024 -n 2 &

Then I start some softsynth[s] (fluidsynth is touchy if rosegarden is started first...??). Start rosegarden. So far, so good. 

Sorry I don't just have the answer for you. :(

This happened to me a while back. Here's what I did.

Change your /etc/make.conf to include +jack +jack-tmpfs and +portaudio if 
needed.
Recompile all the packages with jack support. emerge --update --newuse world 
should do it i guess.
Emerge qjackctl.
Then emerge rosegarden with -arts and +jack..
Then simply start qjackctl and start jack server before starting rosegarden.

This is assuming that you have timidity++ working properly beforehand and that 
it is started before starting jack.

HTH,
