[PlanetCCRMA] No Midi

Hello !

I've been enjoying CCRMA for a couple years now, but recently
wiped my system of Fedora 1 and installed Fedora 3.

Now, I'm having problems getting MIDI to work, although PCM seems
to be working fine.

I've looked over some of the past posts and think I've ruled out the
common problems, although I'm obviously missing something.

When I start 'rosegarden' I get:
      Error while initializing the sound driver:
       device: default can't be opened for playback (Device or resource busy)

in a GUI window, and on the command line:
     JackDriver::initialiseAudio - initialised JACK audio subsystem
     ALSA lib seq.c:928:(snd_seq_open_noupdate) Unknown SEQ default
     *** glibc detected *** double free or corruption (!prev): 0x080cce00 ***
     Launched ok, pid = 5872

When I run 'muse' I get:

ALSA lib seq.c:928:(snd_seq_open_noupdate) Unknown SEQ hw
Could not open ALSA sequencer: No such file or directory

kmid seems to start up fine (no errors)... and SEEMS to run, but
I don't hear any sound.  I'll admit I don't use kmid, and so not sure
it's behaving properly besides that.

I do not have any external MIDI devices hooked up right now....
I'm trying to just get it to my sound card ( snd-intel8x0 ) which is
built in to the motherboard.

I do have a Brooktree audio/video capture card and usb audio
device attached too, so have these entries in my /etc/modules.conf:
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF verion 1.0.9rc1 ---
#alias char-major-116 snd
#alias char-major-14 soundcore
#alias sound-service-0-0 snd-mixer-oss
#alias sound-service-0-1 snd-seq-oss
#alias sound-service-0-3 snd-pcm-oss
#alias sound-service-0-8 snd-seq-oss
#alias sound-service-0-12 snd-pcm-oss
alias snd-card-0 snd-intel8x0
options snd-intel8x0 index=0
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && \
        /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; \
        /sbin/modprobe -r --ignore-remove snd-intel8x0
alias sound-slot-0 snd-intel8x0
# --- END: Generated by ALSACONF, do not edit. ---

alias snd-card-1 pwc
options snd-card-1 index=1
install pwc /sbin/modprobe --ignore-install pwc && /usr/sbin/alsactl
restore >/dev/null 2>&1 || :
remove pwc { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove pwc

alias snd-card-2 snd-usb-audio
options snd-usb-audio index=2

The commented out lines had not been commented, but after looking
at my old conf file (Fedora 1) I didn't see those particular lines, so I've
been doing some testing.

I also noticed I don't have a /dev/sequencer, although not
sure that's necessary.

I'm not sure how to tell if the alsa drivers are loaded. Nothing with
"alsa" seems to be listed in the output of  ps afx  or  lsmod.

Any help would be great !
