/dev/sequencer: not found?

Post by Chaotic Though » Sat, 11 Mar 2000 04:00:00



I'm trying to get Linux to support my sound hardware (A Gus PnP) and have not
been enjoying complete success thus far. I want to use the ALSA drivers for
this card, but I can't get MIDI working.

I'm using Linux kernel version 2.2.14, with Sound support compiled in, but
sound.o does not load. I coconfigured the ALSA drivers with the
"--with-isapnp=yes --with-sequencer=yes" options.  After doing the
"./configure;make install" process on the alsa-drivers, alsa-lib, and
alsa-utils packages, I did "modprobe snd-card-interwave" to load the kernel
modules in. I also ran the "./snddevices" script (before I loaded the module)

After that, sound works just fine but only PCM. Trying to play a midi file
using the playmidi utility gives the error "/dev/sequencer: not found" or
something similar. My card is initialized properly by the ALSA. I don't
understand what I'm doing wrong here. If anyone can help, I'd appreciate it.

I have a similar problem with a different setup, and rather than beat
my head against it, I just use timidity instead of playmidi.  It
sounds better, anyway.  

I think timidity isn't really using the MIDI on the soundcard, it's
converting the MIDI information to sound information using the cpu.

Yes, timidity is a software synthesizer and it uses cpu to do its magic. It
definitely sounds worse than my GUS PnP, though. And I need /dev/sequencer
support for things like DOSemu to use dos midi sequencing programs. Timidity
just plays MIDI files.

1. sound problem: /dev/sequencer not found

Hi all, I recently compiled kernel 2.4.1 with sound and the opl3 midi
driver (soundblaster 16 card).  Everything seems to be working OK with
playing wavs, mp3s, etc, but I can't get midi to work.

If I try "xplaymidi filename.mid"  I get "/dev/sequencer: no such device
or address".  How do I fix this?  The append line I'm passing in
lilo.conf is:

append = "sb=0x220,5,1,5 opl3=0x388"

Relevant kernel output (at boot):

Que pasa?

6. Can't find module char-major-5, sound busy no /dev/sequencer nor synth0

7. /var/log/secure and "Firestarter" ?

8. /dev/sequencer not configured

9. /dev/audio and /dev/sequencer problems!

10. sync /dev/dsp & /dev/sequencer?

11. Rerouting /dev/midi and /dev/sequencer to tiMIDIty?

12. /dev/sequencer and /dev/midi
