Greets to all,
I am experiencing problems during the build (and consequently modprobe)
process of Kor Nielsen hacked version of kfusd module for OSS2JACK,
fusd-kor-1.10-9.
I am on Slackware 10.1, kernel 2.6.13 and 2.6.13.1, gcc-3.3.4, glibc-2.3.4.
As far as kernel version 2.6.12.2 the module has always been built and
modprobed correctly, these are excerpt from console:
root@slack101-sal:/usr/src/fusd-kor-1.10-9# make
.
.
[build output...]
.
.
make -C /lib/modules/2.6.13.1/build
SUBDIRS=/usr/src/fusd-kor-1.10-9/kfusd
EXTRA_CFLAGS=-I/usr/src/fusd-kor-1.10-9/kfusd/../include modules
make[2]: Entering directory `/usr/src/linux-2.6.13.1'

root@slack101-sal:/usr/src/fusd-kor-1.10-9#
The module does get built, but is not functional:
Upon trying to insmod, or install, depmod and modprobe the module I get
this (quite expecting it...):
root@slack101-sal:/usr/src/fusd-kor-1.10-9# modprobe kfusd
FATAL: Error inserting kfusd (/lib/modules/2.6.13.1/misc/kfusd.ko):
Unknown symbol in module, or unknown parameter (see dmesg)
Here is the bottom of dmesg output:
kfusd: Unknown symbol class_simple_device_add
kfusd: Unknown symbol class_simple_destroy
kfusd: Unknown symbol class_simple_device_remove
kfusd: Unknown symbol class_simple_create
kfusd: Unknown symbol class_simple_device_add
kfusd: Unknown symbol class_simple_destroy
kfusd: Unknown symbol class_simple_device_remove
kfusd: Unknown symbol class_simple_create
Maybe something changed in 2.6.13 and introduced this problem?
Has anyone been able to use OSS2JACK with 2.6.13 ?
Thanks in advance!

Yes, it did.

I run 2.6.13-rt4 with oss2jack. I have never used this solution before
and I experience different troubles like crackles in the sound and I'm
also not able to feed a jack stream into it. It connects but it's not
putting the stream into the oss app.
I also have to run oss2jack with +s.
I'll do some more testing before I ask anything specific, but please
report back if you get it to work with inputs and no crackles in the
sound.

It really depends on the application. Good results are with (according
to info on website):
* mplayer
* artsd (and thus all the kde applications)
* xmms
* Macromedia Flash
* xine
* Totem
* esd
* SoundTracker
* Frozen Bubble
* GStreamer (osssink)
* Quake 3
* Audacity
* Skype
I dind't manage to make it work with Audacity, though...
With Skype I had no problem:

I'll do some more testing before I ask anything

Yes, I know, but none of the mentioned apps do voip;). At least not
free ones. Playback only apps works fine.
I've tested with: asterisk, mplayer, audacity, ecasound and sox.
I dind't manage to make it work with Audacity,

Right, I get "Error while opening sound device" no matter what rates
and depths I set it to.
With sox and ecasound, it has to be suspended and then killed. The
file produced are either full of errors (ecasound) or empty (sox).
I'd really like to find out why audacity don't work since it's
mentioned to work. It might be related to the patch and
linux-2.6.13. I've never run oss2jack before this. Anyone gotten
audacity any free apps to work with inputs at all with linux-2.6.13?.

I use with success:
Gnome Wave Cleaner
Avidemux2
ReZound (playback only)
Skype
sox
GNUsound (native JACK supports segfaults)
^^^^^^^^
'- this one works with inputs, (only at JACK samplerate)
if you play with OSS preferences in the program
ZynAddSubFX (it gives me rock solid performance even upon loading a
PADsynt instrument) (see link below)

I'm using oss2jack since 2.6.10, before the patch to fusd-kor and before
oss2jack supported audio input at all, and Audacity never worked for
me... :(
BTW, have you experienced the Jack crackling problem I described here?
http://music.columbia.edu/pipermail/linux-audio-user/2005-August/025787.html
I'm gonna buy an M-Audio Delta44 now, and I would be happy if that
occasional crackling wouldn't happen anymore...

Damn.

Hmm, anyone else got any free app working with inputs? (that does not
have the same samplerate).

http://music.columbia.edu/pipermail/linux-audio-user/2005-August/025787.html
Well, a very, very long time ago I had crackling;). I can help you
with this problem, but you need to do a couple of things first:
compile newest alsa-*, kernel with mingo realtime patch, jack and all
other apps involved, disable acpi and put your spu on irq 9 alone,
then start a fresh mailinglist thread if you still got the problem;).
I would be happy if that occasional crackling
wouldn't happen
anymore...
If you still find crackles after the above procedure, you should start
looking at realtime priority, PCI latency, DMA for the hd, filesystem
type, IRQ priority and max_transfer_size for the hd.

Yes, me, with sox, using the -c1 switch to only open one channel; I
can record at whatever sample rate it seems. If I try to open two
channels, with -c2 it just hangs and don't write any data.
It seems the problem lies with oss2jack/kfusd.
The voip app, kphone does something interesting because the ioctl
returns two channels, forcing it into "stereo mode".
dspoutoss:80
ioctl( audio_fd, SNDCTL_DSP_CHANNELS, &channels)
dspoutoss:91
if( channels == 2 ) {
printf( QObject::tr("WARNING: nonmonophonic driver, forced into\
stereo mode (experimental)") + "\n" );
audio_stereo=true;)))})
This really is probably not the problem, since the sox test shows
there is a problem with opening two channels.
I'll try to test with some other apps to nail it more down. Please
scream out if you find anything out.

Same as with kphone; I do hear the other end, but I'm unable to send
data.

It sure did. After reporting this to the author, he released a new
version of oss2jack and kfusd which is now working with kphone;) (only
one tested yet).
I do have some serious latency issues, but I need to test more and
report back.
I'm very glad that I'm finally able to use free VOIP applications with
jack. The project is actively maintained and the future looks bright
for jackifying OSS apps;).
I've requested that a mailinglist be started for this project.

Something is seriously wrong with kphone and oss2jack, but I will

great success; about 200-300ms stable latency for 3h calls and very
clean sound with speex. All is well in jackified voip land.
I'm still looking for a command line solution, of course;). Using
asterisk with oss2jack yielded very bad results as well.

Does anyone have experience using audacity via oss2jack? I know there is
some support for using audacity/portaudio via jack, but last I heard
there were some issues with connecting/disconnecting from the graph way
too often, so I'm just curious if oss2jack is another option.

A teaser: the next version will have a feature to open more devices so
that each app could use it's own device;).

Great, and a useful option would be a commandline switch to have capture
only or (more often used) playback only operation, if you need it.
P.S. I managed to make Audacity play well with oss2jack, patching the
Audacity source by grepping -r "/dev/dsp" in the sources and dumbly
changing "/dev/dsp" with, say, "/dev/dsp20", then calling
"oss2jack
Audacity -n20" (I modified oss2jack source as well, changing "oss-dsp"
into argv [1], real ugly, I know... ;) )

A more thorough approach might be to start the server, then it does
nothing and you send it messages what to do;)
oss2jack-interface --add device --name dsp4 --mode rw
..or something. (easily scriptable)

Seems this only happens with kphone, in both OSS modes
The OSS modes are "Read/Write" and "ReadOnly/WriteOnly". I experience
much less crackles when in "ReadOnly/WriteOnly" and in this mode I
specify /dev/dsp for both devices.
