Hello list,
I'm new to audio recording, and have a couple of unsolved questions
after getting my basic setup working. I've searched the archives
using google (is there a list-specific search somewhere?), but haven't
found a solution. I'm currently using
- pc with sblive! soundcard
- 2.6.20-rt8 kernel, by patching stock debian kernel 2.6.20
- external evolution usb midi keyboard
- external 4-channel mixer
- timidity as a soft-synth
- ardour 2.0 for audio recording
- rosegarden for midi recording.
- jack + qjackctl to connect it all
All that seems to work reasonably well, and since the realtime kernel
there are no noticeable latency problems. I do get the occasional
xrun (about once every 5 minutes or so) but it hasn't been
bothersome.
The thing I cannot get to work is midi playing through the sblive
soundcard. I've followed countless howto's, yet all I get is dead
silence. The card works for normal audio, all modules including
snd_emu10k1_synth and snd_emux_synth. I've tried loading the
soundfont like so
aweset -v init -> initializing AWE chip
asfxload 8mbgmsfx.sf2
It seems to work if I inspect /proc/asound/card0/wavetableD1:
Device: Emu10k1
Ports: 4
Addresses: 17:0 17:1 17:2 17:3
Use Counter: 1
Max Voices: 64
Allocated Voices: 61
Memory Size: 134217728

Allocated Blocks: 528
SoundFonts: 1
Instruments: 1849
Samples: 526
Locked Instruments: 1849
Locked Samples: 526
But all that comes out is dead silence, wether I route the keyboard to
the soundcard or try through rosegarden. Here's the output of
aconnect -lio just after loading the soundfont:
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
Connecting To: 15:0
client 14: 'Midi Through' [type=kernel]
0 'Midi Through Port-0'
client 16: 'SBLive! Value [CT4670]' [type=kernel]

client 17: 'Emu10k1 WaveTable' [type=kernel]
0 'Emu10k1 Port 0 '
1 'Emu10k1 Port 1 '
2 'Emu10k1 Port 2 '
3 'Emu10k1 Port 3 '
client 20: 'MK-225C USB MIDI keyboard' [type=kernel]
0 'MK-225C USB MIDI keyboard MIDI '
I've tried to connect 20:0 to 16:0, and also to 17:0,1,2,3, to no
avail. What should I be connecting? Any other hints as to why my
sblive card won't play midi?
Here's the output of lspci -v:
00:0d.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 04)
Subsystem: Creative Labs CT4850 SBLive! Value
Flags: bus master, medium devsel, latency 32, IRQ 17
I/O ports at a400 [size=32]
Capabilities: [dc] Power Management version 1
Any help will be much appreciated.
Kind regards,
Hein Zelle

Have a look in alsamixer on the CLI. You do need the control "Music" to be up.
This control used to be called "Synth" which made more sense. I've just
checked it on Etch with my 225C, and it plays ok, but a bit quiet. I just
connected the keyboard (72) to 0 Emu10k1 Port0.

Thanks for the tip, but it appears to make no difference. The control
is still called "Synth" on this card, it's relatively old (not exactly
sure how much). I must say the alsamixer is acting strangely with
this card - some controls can't be changed, some (including synth)
won't be muted. The synth does let itself be adjusted. The total volume
doesn't respond to "pcm" or "main", I need to use "Wave
Surround" instead.
I've connected the midi keyboard to each of the soundblaster ports,
but no sound sofar.

Ok. Does the usb midi keyboard otherwise work. For example, can you use it
with ZynAddSubFx. You need to just connect the keyboard to ZynAddSubFx in
qjackctl's midi connections if your using Etch or Lenny.
Have you tried with an earlier kernel, just in case you have made some error
with your, roll your own one?
btw. Which Debian version are you using?
If you are using KDE, you can use Kmid to check out if the midi is working.
I've attached a file, if you don't have any midi ones.

I think you have the speakers plugged into the rear output. The

I can't believe I fell for that, I thought black was the logical
"primary" audio output. I'm only using regular 2-channel audio
through a mixer and stereo system.
Banging my head the wall won't make things better, but I sure feel
like it.
Many thanks!

No problem. Glad it helped! It's a fiddly card, but very good for
the price!
If you are ever dropping by in London, I wouldn't say no to a
beer!!
Best wishes,
