1) Is the Trident Wavetable working ?

http://www.alsa-project.org/~iwai/writing-an-alsa-driver/x84.htm

There is no Makefile inside /alsa-kernel/Documentation/Docbook

2) How can I converted the latest version of writing-an-alsa-driver.tmpl
to HTML format

3) Is the information about ALSA sequencer in
http://www.alsa-project.org/~iwai/lk2k/lk2k.html still valid for ALSA
1.0.x ?

4)  In addition to the callback functions used in Midi sequencer
interface, what other functions/modules will the wavetable synth (kernel 
client) need to be implmemented ?

static snd_midi_op_t vortex_midi_ops = {
	snd_vortex_note_on,
	snd_vortex_note_off,
	snd_vortex_key_press,
	snd_vortex_terminate_note,
	snd_vortex_control,
	snd_vortex_nrpn,
	snd_vortex_sysex,
};

http://cvs.sourceforge.net/viewcvs.py/alsa/alsa-utils/seq/

5) Is the aplaymidi the only tool to test and debug the wavetable synth
? ( Any GUI application )

Refer to http://www.3dsoundsurge.com/archive/week16.htm
(iii) OPL3 Support: Both Windows DOS boxes and real-mode DOS now support
4-operator OPL3 FM synthesis, in addition to 2-operator OPL2 FM synthesis.

6) Do au88x0 support OPL3 ?

The "vortexcontrol" use alsa-lib API to play the audio
samples inside au30gm.arl through hw:0,0.

7) How can the audio sample be played within the driver using the
  soundfont through hw:0,0 in a 16 voice synth for au8810 (without WT) ?

Very limited.  It's no proper "MIDI" wavetable implementation.
IIRC, only a module player worked with trident driver.

It's in alsa-driver/doc/Docbook.

Run "make pdfdocs".

No idea. I don't have one. I just looked at the datasheet of the trident
4DX chip and found very similar to the aureal chip, when looking at the
big picture.

We need the WT engine working. The rest is just a matter of writing the
glue code (pretty straitforward).

No. It supports some memory registers to aid software emulation, but
there is no real OPL hardware onboard the aureal chips.

Thats because its just for hearing a sample. Its not even close to what
has to be done for a Wavetable implementation. The higher level arl
soundbank interpreter is very valuable, but on the hardware side we are
missing the WT engine support.

> 7) How can the audio sample be played within the driver using the

The au8810 does not have the WT engine, so wavetable synthesis has to be
done with software emulation, and feeding the resulting audio into a
dedicated ADB PCM channel.

The midi port only need to support 16 voices, the 16 sample rate
convertors are just enough to produce 16 voices using the mono sound
samples in the soundfonts au30gm.arl

http://www.alsa-project.org/alsa-doc/alsa-lib/seq.html

Please correct me if I am wrong, there seem to be no documentation on
those ALSA sequencer functions such as snd_seq_create_kernel_client,...

What will be needed for a proper "MIDI" wavetable implementation ?

In snd_vortex_playback_hw_adb, .rates = SNDRV_PCM_RATE_CONTINUOUS

1) Can the sample rate convertor be used to perform pitch shift ?

2) Can panning be done by changing the mixin-mixout gain for left/right
channels of each voice ?

The current alsa driver do not even use the timer VORTEX_SMP_TIME or
timer interrupt VORTEX_SMP_TIMER

3) Is there any way to find out the resolution of the timer ?

Have a look at the OPL4 driver, it's the simplest wavetable driver.
However, it doesn't support downloading instruments.

while you guys are working on that driver, is there anyone that has a 64bit 
setup? if not, i'd like to test out your driver in 64bit. i still have a 
number of issues with it (my card is an au8810).

i cannot regularly check it, cause i only have one PC and it's a server, but 
at nighttimes, i guess i can test it out a little.

good luck, AL13N

Yes, we have a bug tracking system:

Each report is forwarded to alsa-devel ML, too.

Yes, but the ADB engine is intended for normal wave playback. The WT
engine is more suited  for Wavetable stuff. It also has some envelope
filters and such for effects. With only 16  voices, you will run out of
them pretty fast (overlapping notes).

Yes.

Yes, but again, we should better use the WT processing block which is
there for that purpose.

Only enough for solo of single instrument and no reverb/chrous effect
when using ADB.

Some of the "pitch-shift" rates of the sample seem to be outside the
5000Hz-48000Hz range of hw:0,0

How can I play the soundfont sample loaded in memory through hw:0,0 in

The clock VORTEX_SMP_TIME seem to tick at 12.288Mhz (256 * 48000Hz)
which is one-quarter of the 49.152Mhz oscillator on all the vortex
sound cards.

Is there any way to disable the loading of the ALSA and au88x0 during
boot if some fatal bug occur when testing the timer interrupt
VORTEX_SMP_TIMER ?

I don't know of arl format, but if it's not compatible with
soundfonts, stciking with the current soundfont handler doesn't make
sense, IMO.

"Another new feature in 2.048 drivers is the possibility to upload SF2

1) Why samplerate is missing in soundfont_sample_info_t ?

The samples in au30gm.arl have different samplerates.

ADB instead of WT) ?

3) Refer to

The sample rate is defined in soundfont_voice_info_t.

The functions in util_mem.c are used to allocate/free blocks in a
(virtually) linear address space dynamically.  These functions
themselves are no replacement for kmalloc/kfree at all.

Re: au88x0_synth

If I am using 16 SRC (hw:0,0) to play 16 voices instead of 64 voices WT 
engine, Is it possible to create a snd_pcm_substream_t for each voice in 
snd-au8830-synth and calling snd_vortex_pcm_open(), 
snd_vortex_pcm_hw_params(), snd_vortex_pcm_prepare(), 
snd_vortex_pcm_hw_free(), snd_vortex_pcm_close() in snd-au8830 ?

int snd_vortex_synth_bzero(vortex_t *vortex, snd_util_memblk_t *blk, int
offset, int size)
{
	int page, nextofs, end_offset, temp, temp1;
	void *ptr;
	vortex_memblk_t *p = (vortex_memblk_t *)blk;

	end_offset = offset + size;
	page = get_aligned_page(offset);
	do {

			temp = temp1;
		ptr = offset_ptr(vortex, page + p->first_page, offset);

			memset(ptr, 0, temp);
		offset = nextofs;
		page++;
	} while (offset < end_offset);
	return 0;
}

/*

I do not have any 64bit setup, are you sure that your 64bit patch is
correct ?

http://kerneltrap.org/node/3848

snd-au88x0 use the following macros to perform read/write of 32bit data
from/to Memory Mapped I/O

#define	hwread(x,y) readl((x)+((y)>>2))
#define	hwwrite(x,y,z) writel((z),(x)+((y)>>2))

Would you provide the result of "lspci -vvvn" to find out the content of
PCI BAR0 of your au8810 card ?

What is the model of your au8810 card (e.g. Vortex Advantage, SQ1500,
SoundCom V90) ?

Do your 64bit machine has more than 4Gb memory ?

Do your configure all the sound-apps to use ALSA instead of OSS ?

This is abnormal, au8810 has 16 SRC and snd-au8810 can play either 16
mono streams or 8 stereo streams concurrently.

Use alsamixer to find out which ac97 codec on your au8810.

Do you have any application using gameport, mpu401 or OSS  ?

Do the log indicate the snd-au8810 is loaded properly ?

snd-emu10k1 use PIO.

Would you post the content of /etc/modprobe.conf ?

well, i'm using it every day. and before the patch at modprobe time i got 
kernel oops... so...

I don't do much special things with it, I use it for line in and PCM and 
stereo output, i don't use the equalizer or anything fancy...

> http://kerneltrap.org/node/3848

I'm still using kernel 2.6.8, though it has a fairly large number of patches, 
but since i didn't decide this, it may very well be in there and I may have 
just used this... you may want this implemented, since both PIO and MMIO is 
used in your driver.

i think the memory mapped I/O is 64bit in 64bit CPU's.

haven't gotten any gameport to work, not on the emu10k1 nor the au8810, never 
use MPU401 and i use OSS emulation on games like AA, ET, OpenAL...

I'm not using that right now:

if i want to use sound after bootup (which doesn't happen often at all), I do:

modprobe snd-au8810
modprobe snd-emu10k1
modprobe snd-pcm-oss
alsactl restore -f /data/path/mixer

May be your problem is related to the well-known conflict between
Vortex cards and VIA chipsets ?

You better post your problem on the openvortex-dev mailing list and
remember to mention that you are using VIA chipset.

The rate of some samples are 44100Hz but most of the samples are not 44100Hz

It seem that only layers of generators and samples are loaded from the 
soundfont file and none of the modulators are passed from the soundfont 
to the wavetable synth.

Re: au88x0_synth

[Raymond]

It is abnormal to get the message "vortex: reg error" on your au8810, it 
does not appear in my au8830.

http://savannah.nongnu.org/support/?func=detailitem&item_id=102951

You will need to find out the code which cause "vortex: reg error".

You may try the following:

1) Remove code relating to SPDIF ( only SQ1500 and au8830 has SPDIF )

2) use hwwrite(vortex->mmio, VORTEX_CODEC_EN,
hwread(vortex->mmio, VORTEX_CODEC_EN) | EN_CODEC0);

No need to use (EN_CODEC0 | EN_CODEC1 ) since your au8810 only has 
stereo codec.

You can use .openalrc to configure OpenAL to use ALSA

(define devices '(alsa))
(define speaker-num 2)
(define alsa-out-device "hw:0,0")
(define alsa-in-device "hw:0,0")

you sure about that, the card told me it had stereo and 4 speaker mode? or are

Re: au88x0_synth

[Raymond]

Would you post the result of "more
/proc/asound/au8810/codec97#0/ac97#0-0+regs" ?

http://www.wolfsonmicro.com/products/digital_audio/ac97/WM9701/

Unless ALSA mis-identify the AC97 codec on your au8810, WM9701A is a
stereo codec

Do alsamixer or windows driver told you that your card has "4 speakers
mode" or your card has out1,out2 jacks and coaxial SPDIF ?

http://www.watch.impress.co.jp/akiba/hotline/991106/newitem.html#19


EN_CODEC0 - enable the front channels of au88x0 to ac97 codec

EN_CODEC1 - enable the rear channels of au88x0 to ac97 codec

I have no windows or a 32bit OS. the card manual told me it had a 4 speaker 
and stereo mode, i never used the 4 speaker mode, so I can't be sure of 
anything like that. I'll try and look for the card manual some time.

I'd like to have other stuff fixed first, if you don't mind, my volume is 
randomly changing at certain points (the 32bit compile didn't have that) and 
sometimes the audio modules hang (since that patch, i haven't had that 
problem anymore).

furthermore, i notice that I can't choose between 41000 and 48000 Hz anymore 
in alsamixer, and that the equalizer sliders look odd (though i never used 
them). i can tell you only what changed versus the 32bit mode, and 
with/without the patch.

i got the vortex reg error in the 32bit version too. and i never had a 
problem.

The enumerated SPDIF sample rate (32000,44100,48000) control has been
replaced by the IEC958 control.

http://sourceforge.net/mailarchive/message.php?msg_id=11102457

The easy way is to use "vortexcontrol" to set the 10-bands 
(31,63,124,250,500,1K,2K,4K,8K,16K Hz) stereo equalizer to Jazz, Pop, 
Classical, Rock, Dance or user defined, otherwise you need to use 
alsamixer to set the equalizer in bypass mode.

Do "vortexcontrol" need any patch to work in 64-bits platform ?

Why do you use dmix when both cards support hardware mixing ?

i don't use dmix, this aplay -L output comes from my distro,  right now, i'm 
using either default, or plug:hw:1 (for the SBLive, connected to a surround 
heaphone)

Re: au88x0_synth

[Raymond]

What do you mean when you say "the equalizer sliders look odd" ?

Would you post the settings of the equalizer from "/data/path/mixer" or 
/etc/asound.state ?

 From your png, it seem that you are not using the alsamixer in the 
latest version of alsa-utils.

The alsamixer or amixer are unable to display EQ Peaks correctly, the EQ
Peaks is a volatile read-only kcontrol which return 20 EQ peak values 
from the 10-bands stereo hardware equalizer in au8810/au8830.

The graphic equalizer in vortexcontrol use a timer callback to read and 
display the EQ peaks when EQ Enable switch is on. (attached vc_eq.png)

When you upgrade from ALSA 1.0.8 to ALSA 1.0.9 ,the SPDIF sample rate 
control ( ALSA 1.0.8 ) has been replaced by the IEC958 control ( ALSA 
1.0.9 ).

You will need to delete old setting in "/data/path/mixer" and use
alsactl to store the new setting, otherwise error will occur if you try 
to use alsactrl to restore the value of emunerated spdif sample rate 
control settings saved by the previous ALSA version to the au8810 in 
ALSA 1.0.9 driver.

Your /etc/asound.state seem OK and the equalizer is OFF.

After eight instances of "mplayer" playing stereo music concurrently in 
my 32-bits machine and start an instance of aplay.

aplay outls.wav
Playing WAVE 'outls.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, 
Stereo
aplay: set_params:935: Unable to install hw params:

aplay abort as there is no more SampleRateConvertors available.

There is no deadlock or hang. After the "mplayer" finish playing and 
release the SRCs, I can start another instance of ALSA application to 
play music.

since i'm using alsa CVS for driver, kernel and lib; i'll use utils from CVS 
as well...

didn't know that, in the previous versions, i know that all these peaks were 
listed as mono sliders, not partly mono and stereo...

vortexcontrol looks nice, from what alsa CVS package is that?

thanks for the info, but since i'm not using SPDIF, this was never any 
relevance for me

actually, this one warning has been there for quite some time, i donno if it's 
emu10k1 or au8810... (i think even in 32bit, not sure about that), when 
storing it, modprobe -r and modprobe again, and restoring, the warning 
stays...

> Your /etc/asound.state seem OK and the equalizer is OFF.

never used the equalizer, i wasn't able to put the whole asound.state file, (i 
removed the emu10k1 stuff), cause the size of the mail was too large...

I'm going to try to do the same thing with xine and CVS aplay, see what 
happens...

If WT code compiled as a separate module au88x0-synth , it cannot direct 
call those functions in au88x0 module (e.g vortex_mix_setvolumebyte() )

Also there are a lot of warning messages "static function declared 
static but never defined" in au88x0.h because WT code need to include 
au88x0.h to get the definition of vortex_t.

#define SNDRV_SEQ_DEV_ID_AU88X0_SYNTH CARD_NAME_SHORT "-synth"

	if (snd_seq_device_new(card, 1, SNDRV_SEQ_DEV_ID_AU88X0_SYNTH,
			       sizeof(snd_vortex_synth_arg_t), &wt) < 0
	    || wt == NULL) {
		printk(KERN_INFO "Can't initialize au88x0 wavetable synth\n");
	} else {
		snd_vortex_synth_arg_t *arg;
		arg = SNDRV_SEQ_DEVICE_ARGPTR(wt);
		sprintf(wt->name, "%s Synth",CARD_NAME_SHORT);
		arg->chip = chip;
		arg->index = 1;
	}


As WT is present on the au8820/au8830 chip and not on another chip of
the sound card. (WT registers can be accessed by using vortex->mmio )

Is there any alternative way for keeping the WT code within module
au88x0 instead of a seperate module au88x0-synth ?


	if ((err = snd_device_new(card, SNDRV_DEV_SEQUENCER, wt, &ops)) < 0) {
		return err;
	}
