[PATCH] Audigy LS driver ready for inclusion into alsa-driver.

[PATCH] Audigy LS driver ready for inclusion into alsa-driver.

[James Courtier-Dutton]

Audigy LS driver is now ready for inclusion into alsa-driver.
Get it from http://www.superbug.demon.co.uk/alsa
The "install.txt" tells one how to patch the current alsa-driver 1.0.5a 
with it, and also explains where some other files should be put.

The indentation might need correcting before inclusion into the 
alsa-driver cvs.

Cheers

Are you going to work on any other Audigy-series drivers, e.g. Audigy 2 ZS?
I'm finding the emu10k1 driver in alsa-driver-1.0.5a has serious problems
with random intermittent distortion of the soundfont samples while they are
being played on the soundcard's MIDI synthesiser, e.g. using aplaymidi -p 65:0.
"Random intermittent distortion" means, e.g. the sound during MIDI playback
becomes "muffled" for a minute or two and then returns to normal sound quality,
or the sound wrongly becomes mono for a few seconds, and then
returns to stereo.
Also, it seems emu10k1 does not load soundfonts correctly,
especially if you ever use any really large 25MB soundfonts.

I don't have an Audigy 2 ZS, so unless someone donates one, I can't help 
you there.

Can you post to a web site your soundfonts file, and instructions on how 
to use them with the creative cards, I might be able to help.

I have a cheepo Audigy 2 (old version) that I might be able to reproduce 
your problems on.

I don't work with MIDI much, which is why I have not added MIDI support 
to the Audigy LS driver at the moment.

At the moment I also have an Audigy LS (5.1) which seems to have
similar problems to the Audigy 2 ZS.

The 25MB piano soundfont is here:
http://www.wstco.com/pianosounds/freesoundfont.htm
Please note the author Warren has told me his soundfont is not re-distributable.

ALSA soundfont loading:  asfxload WST25FStein_00Aug14.SF2
ALSA OSS-mode soundfont loading:  sfxload WST25FStein_00Aug14.SF2

Sample MIDI files for piano: http://members.aol.com/sdrodrian/

 $ aplaymidi -l
  Port    Client name                      Port name
  62:0    Midi Through                     Midi Through Port-0
  64:0    Audigy MPU-401 (UART) - Rawmidi  Audigy MPU-401 (UART)
  64:32   Audigy MPU-401 (UART) - Rawmidi  Audigy MPU-401 #2

  75:0    Virtual Raw MIDI 1-3             VirMIDI 1-3

 $ aplaymidi -p 65:0 midi_music_file.mid

An even better test would be to do some experiments on an Audigy using
Rosegarden 4 0.9.8 for MIDI playback, JACK audio, etc

I hope you will add MIDI support; I think it would be a great improvement.

I have played some .mid files now, but I have not noticed any problems 
with my Audigy 2.

When I downloaded the fonts file, mine had a different name to yours.
Yours: WST25FStein_00Aug14.SF2
Mine: WST25FStein_00Sep22.SF2

Can you provide me with a .mid file that shows the problems and is easy 
to reproduce the problems?

Cheers
James

It makes no difference which of these two soundfonts is used.

As I said in my original email, the sound distortion problem is intermittent.
I haven't found a way to reproduce it.  However, if I use emu10k1 for MIDI
I usually encounter the sound distortion problem at least once every hour or so.
It seems to be a driver problem; it's not dependent on a particular MIDI file.

Steve Conrad was the first to mention an emu10k1 problem with soundfonts:
https://sourceforge.net/mailarchive/message.php?msg_id=7897993
The soundfont problem seems to occur whenever I first load the 25MB piano
soundfont and then later load the manufacturer's synthgm.sbk
soundfont (http://christian.datzko.ch/computer/synthgm.sbk).
Many but not all instruments are silent (piano usually works).

check /proc/asound/card0/wavetableD* file whether all instruments are
loaded.  you can see there the memory usage,  number of instruments,
etc.

Experiment 1:
-------------

Load the 25MB piano soundfont file:
 $ asfxload /tmp/WST25FStein_00Aug14.SF2 
 $ cat /proc/asound/card0/wavetableD*
Device: Emu10k1
Ports: 4
Addresses: 65:0 65:1 65:2 65:3
Use Counter: 0
Max Voices: 64
Allocated Voices: 0
Memory Size: 134217728
Memory Available: 108226960
Allocated Blocks: 45
SoundFonts: 1
Instruments: 4078
Samples: 44
Locked Instruments: 4078
Locked Samples: 44
 $ wget http://members.aol.com/myworks/r-c-no02.mid
 $ aplaymidi -p 65:0 r-c-no02.mid
In this case, you can hear music from the Audigy 2 ZS.

Experiment 2:
-------------

Load the manufacturer's Standard GM Midi file:
 $ asfxload /etc/synthgm.sbk 
 $ cat /proc/asound/card0/wavetableD*
Device: Emu10k1
Ports: 4
Addresses: 65:0 65:1 65:2 65:3
Use Counter: 0
Max Voices: 64
Allocated Voices: 0
Memory Size: 134217728
Memory Available: 134213632
Allocated Blocks: 1
SoundFonts: 1
Instruments: 569
Samples: 152
Locked Instruments: 569
Locked Samples: 152

 $ wget http://members.aol.com/myworks/r-c-no02.mid
 $ aplaymidi -p 65:0 r-c-no02.mid

In this case, there is total silence from the Audigy 2 ZS.

only 4096 bytes (= 1 page) allocated.  i guess this file is for ROM
soundfonts on SB AWE boards, not for SB Live/Audigy?

That's odd because the file is 34832 bytes long
(see http://christian.datzko.ch/computer/synthgm.sbk)

Why is asfxload not loading the file properly?

a soundfonts file includes not only the wave data but also the
instrument layer meta data.  in the case of ROM fonts, it includes
only meta data.

it does :)

So, the problem is that synthgm.sbk has meta data but not wave data.
I can't see any option in asfxload to check whether a soundfont file
has meta data only or both wave data and meta data.
It would be useful.  alsa-utils / alsa-tools also don't seem to have
anything for checking this.

It would be nicer if asfxload gave a warning when the soundfont only
has meta data and the soundcard does not have any ROM soundfont.

JFYI, I've committed your audigyls codes into alsa-driver CVS tree.
audigyls.c was a bit modified to shut up compile warnings.
Please send as a patch if you have a newer version.
