How to put 16bit none audio PCM data stream into a 32bit none audio S/P-DIF transport stream?

How to put 16bit none audio PCM data stream into a 32bit none audio S/P-DIF transport stream?

[Gregoire Favre]

Hello,

I have an AC3 receiver which uses the bit flags of the S/P-DIF transport
stream for identifying none audio, and I use the cs46xx driver for my
Hercules Digifire 7.1 (under windows, using the included DVD player I
could have a real 5.1).

Under linux using ALSA, all I get is a cliking sound... does anyone know
how I could solve this (without changing my hardware of course)?

I have looked at the source, but it's far too complicated for me...

Thank you very much,

	Grégoire

define a new plughw PCM device in ~/.asoundrc, and use
that. unfortunately, i don't know how to do that, i just know that you
can do it.

i'm afraid that it's not so easy as it sounds.  it strongly depends
on the hardware driver implementation...

about AC3, 32bit spdif is likely irrelevant.  A52 (AC3) is usally
packed into normal 16bit frames.

does the click happen even if you use alsa-tool's ac3dec?

Yes and no:

./ac3dec -C /data/linux/dvb/from_beyond_the_edge_44k_256kbps.ac3 don't
produce any sound at all now... except ONE big click at the beginning,
same with -P and
./ac3dec -R /data/linux/dvb/from_beyond_the_edge_44k_256kbps.ac3
5.1 Mode 44.1 KHz 256 kbps Complete Main Audio Service
Using PCM device 'iec958:AES0=0x0,AES1=0x82,AES2=0x0,AES3=0x2'

Produces also the same big click and then plays quiete good (only 2.0 no
dolby digital is sent to the receiver...).

Thank you very much,

On my SB Live, with AC3 I use: -
PCM device "iec958:AES0=0x6,AES1=0x82,AES2=0x0,AES3=0x2"

On your example AES0=0x0, whereas I have AES0=0x6.
It is AES0 which sets the non-audio bits in the SPDIF.

Exactly, it's what I also got with other option to obtain ac3...
I have tested lots of option (and other users also have, as reported to
this list) and with ac3 receivershich uses the bit flags of the S/P-DIF
transport stream for identifying none audio loose :-(
Of course I only speak for cs46xx.

Either no sound, or only cliking sound...

Thank you very much,

Well,

I have just copied an expert, Dr. Werner Fink, as he spoke in the
vdr@linuxtv.org mailing list about a problem with AC3overDVB:

"As long as the hardware on the DVB cards are not able to put
the 16bit none audio PCM data stream into a 32bit none audio
S/P-DIF transport stream all receivers which uses the bit flags
of the S/P-DIF transport stream for identifying none audio
loose.  All S/P-DIF data get from the DVB card to not have the
none audio bit set.  AFAIK this is a hardware bug (or better
this is the information I've got from TT) ..."

So I guessed if we are some for which the CS46xx driver don't work with
our receivers with the same sympton (here from the readme of AC3overDVB:
"If your receiver doesn't detect the encapsulated stream (at the
beginning of replay in general) you will hear the digital data played as
PCM data. It's a spiky noise. Don't turn up the volume too much, or the
speakers may be damaged. You have been warned!").

Well, I can't speake from the driver point of view, but with the
hardware it is working, at least under windows...
Maybe Dr. Werner Fink could clarify the situation?

Thank you very much,

Maybe I can try to clarify things a bit.
SPDIF uses 32bits to carry info bits and the audio data. This 32bits is 
called a frame.
The audio data can be anything up to 24 bits, and then the rest are the 
info bits (Like Copy-Protect, Non-audio etc.) .
Most computer audio cards hold the info bits in a single register and 
automatically fill in each frame's info bits using the contents of the 
register.
This leaves the other audio data to be filled by the PCM stream.
Most audio cards only support 16 bits, and very few support 24 bits, and 
virtually none support access to all 32 bits.
So, "iec958:AES0=0x6,AES1=0x82,AES2=0x0,AES3=0x2" sets the info bits 
register, with the audio data coming from the PCM.
For AC3 non-audio spdif, it uses only 16 bits, so we have no problem.
The real problem with AC3 via SPDIF on computer sound cards is the 
sample rate.
A lot of audio cards can only do SPDIF non-audio data at 48khz.
Your sample is requesting 44.1khz which could be the problem.
I do not know if your audio card support 44.1khz non-audio spdif. My SB 
Live definitely does not. My SB Live can output standard PCM data at 
different SPDIF rates, but it does re-sampling in hardware. If I wish to 
bypass the re-sampling hardware (bypass needed otherwise the non-audio 
data gets mangled) in my SB Live I have to use 48khz.

A good source of 48 khz non-audio AC3 sound is playing DVDs.
I know xine handles SPDIF passthru of AC3 soundtracks on DVDs quite easily.
At least this will test if the problem is 48/44.1 khz or something else.

James

Exaclty what do you mean with 32bit spdif ? Sorry, I feel a little bit 
newbie about
the SPDIF protocol specific details.

 From the cs46xx driver point of view, 48khz 16bit audio or AC3 
(non-audio) is the
same thing, 16bit left, 16bit right.
I think the cs46xx HW supports 20 bits resolution, but that's not 
implemented
in the DSP firmware, therefor not supported by the driver (only 16bit 
stereo).

With xine, all I can manage is 2.0 just like with ac3dec, ac3play. Or
clicking sound...

   I have the same problem.  Just FYI, I'm using a Turtle Beach Santa Cruz with
Cambridge Soundworks DTT2500 Digital speakers through the Coaxial IEC958
interface.
   Unfortunately I do not have access to other speakers, so I can't test whether
the receiver is at fault.

non-audio SPDIF on  44.1 khz with the cs46xx driver will definitely not 
work.
Theoretically SPDIF HW supports 32khz 48khz and 96khz (not 44.1khz) but 
32 khz and 96khz rates are not supported by the driver.

So, the SPDIF output is always 48khz, any other rate the DSP will do a 
sample rate conversion to 48 khz, which is fine while it's audio (PCM)
So, outputing sound with 48khz 16bit the DSP wont do any kind of 
procesing to the samples, which is the only case where pass-through can 
work.

All tests I've done with xine it always output the AC3 data on 48khz, 
which should work fine.

Well, maybe with your receiver you are lucky... we have seen those days
in this ml quiete a few people for which it doesn't work with there
receivers.
And as for me it works under windows, I think there is a problem in the
software.

Can you send me a URL so that I can download 
"from_beyond_the_edge_44k_256kbps.ac3" and test it on my system.
My external AC3 decoder requires the info bits to be set to "non-audio" 
just like yours.
I might be able to get it working if I have a sample stream.
I have been wanting to get 44.1khz AC3 working for a long time, but have 
never had a stream to play with.
I understand that you can get some enharnaced CDs now which have 
non-audio AC3 data on them instead of PCM, and I would like to be able 
to play these in linux.

James

Sure: it's from http://www.diatonis.com/downloads.html
I don't know whether it's still there or not, if not, I could send it to
you without problem ;-)

To be honnest, I have no interest in beeing able to hear such "songs":
all I want is to hear 5.1 DVD and 5.1 TV channels...

i can hear ac3 5.1 output over spdif with a terratec xfire 1024
without problems.  i guess it's not the choice of receiver but the
card itself.  there are differences between the cards even with the
same cs46xx chip depending on the hardware implementation.

yes it should be a driver bug.
but note that without the real (problematic) hardware, it's difficult
to check (especially if the system of developers do really work :) ...

Well, I can't speak about ALSA, but for DVB card, it only works with
receivers that detect the encapsulated stream (a lots of DVB users have
tested different receivers).
So I ask if it's really not a problem with some receivers here too...
When I plug my 5.1 to my standalone DVD player, I have two choice:

       	* SPDIF/RAW
       	* SPDIF/PCM

So I only have the choice to change either the card, or my receier...

hmm, then your receiver needs explicitly the non-audio bit.
i guess that my receiver reads the signature bytes for each spdif
frame.  i tested 44.1kHZ ac3 from diatons, and it works on mine.

Well, I have downloaded
http://www.skwmedia.com/media/diatonis/ac3/diatonis_last_summer_rain_ac3_256kbps.zip

It says that the files available before have been removed because they 
appeared to be corrupt.
My it is a corrupt file you are working with.

I don't think so as I got same result with ac3 files I made from
recording from TV, and also when playing DVD...

Please, ignore this 44.1 khz!!!
I really don't care being able to play those, as I have said many times,
all I would like is to play DVD in 5.1 and watch TV in 5.1 also, nothing
else ;-)

Thank you very much for that :-)

What is working under windows, is the DVD ac3 (I have just installed
windows to test the compatibility in hardware betweem my soundcard and
my receiver).

What I meant, if you want to output AC3 on other sample rate's than 
48khz it wont with the current cs46xx driver (44.1 khz AC3 wont work).

The cs46xx driver can improved in many ways, I'm trying to the best and 
work on that. (whenever I got time)

It does not surprise me that it works under Windows, there may be many 
feutures that works under windows, but not under Linux.

Maybe the Windows driver supports AC3 with other sample rates then 48khz 
(if that's the case) or maybe there's another problem.

Re: How to put 16bit none audio PCM data stream into a 32bit none audio S/P-DIF transport stream?

[James Courtier-Dutton]

Gregoire,
You say that in windows SPDIF works fine and you get the AC3 decoded by 
your external decoder.
Does the decoder have any indicators telling you whether it is an AC3 of 
PCM stream ?

So, in linux, when playing a DVD in PASSTHRU mode in xine, does your 
decoder think it is AC3 or PCM ?

If the decoder still thinks it is PCM, then the problem is a bug in the 
alsa-driver, and not the application or sample rate.
If the decoder thinks it is AC3, then we can look at different problems, 
like hardware-resamplers in the way.

Cheers
James

Yes (well, I have an indicator of Dolby Digital).

PCM...

To help you. In order to play this ac3 file, unzip it and you will get a 
.wav file.
Then use this command to send it to the SPDIF socket in non-audio 
passthru mode for your external AC3 decoder to recognise.
aplay -D "iec958:AES0=0x6,AES1=0x82,AES2=0x0,AES3=0x2" a.wav

Where "a.wav" is the name of the .WAV file.

Cheers
James

Well,  something must be wrong with the cs46xx driver. It's hard to know 
what when it's works fine with my receiver. A explication to that could 
be that my receiver ignores the IEC958 status bits and detects the AC3 
from signatures on the stream.

Gregoire:
Please dont give up yet, could you test the atached patch to current CVS.
Then test out different values on the 
"AES0=0x0,AES1=0x82,AES2=0x0,AES3=0x2" parameters like:
"AES0=0x2,AES1=0x0,AES2=0x82,AES3=0x0",
"AES0=0xFF,AES1=0xFF,AES2=0xFF,AES3=0xFF",
"AES0=0x00,AES1=0x00,AES2=0x00,AES3=0x00"  (and any other
values that cames into your mind ... )

Hello,

I'll test as many patches as you'll write ;-)

I have patched my CVS with your patch, then made a
./cvscompile --with-sequencer=yes --with-cards=cs46xx --with-isapnp=no
and sudo make install

And afterthat as root a /etc/init.d/alsasound restart
Then a lots of
ac3dec file.ac3 --device=iec958:AES0=0x2,AES1=0x82,AES2=0x0,AES3=0x2
5.1 Mode 44.1 KHz 256 kbps Complete Main Audio Service
Using PCM device 'iec958:AES0=0x2,AES1=0x82,AES2=0x0,AES3=0x2'

All are playing the file in 2.0 mode, and all test I have done with xine
don't work neither...
Same problem with mplayer (xine and mplayer: either no sound or just the
clicking sound).

Thank you very much,

	Grégoire

Could you recompile with "--with-debug=detect" and try send my some logs 
while you doing your tests ?

I have done it privately, if someone also want the log, just tell me ;-)

Could you repeat the tests with the attached patch applied to current 
CVS. The only changes are some more debug messages.

Just to check, which version of xine ? (I'm using 0.9.18)
"Lord Of the Rings" DTS and Surround 5.1, and "Star Wars II" Surrund 5.1 
works fine forme.

Thanks!

It's a value I could find, is that good?

Yes, for sure!!!

Unfortunately, it's still not working...
If needed I could still send you all the logs :-)

I am sure Dr. Werner Fink know the answer of this question ;-)

Just in case that something differs between DVD's, you never know ...

You're welcome!

Could you just test the new AES0-3.... values, and sendme the logs 
again. (check the SP_SPDOUT_CSUV in logs outputs, i would like it to 
have 0x02820302 value)

Let me guess, I did not work ? Well, guess what, I got new "this time 
hopefully working" patch,
so if you like to apply it to CVS and test again -;)

Could you also test with:
AES0=0x40,AES1=0x0,AES2=0x41,AES3=0x40 (all bits wrapped)

Then I got a question about the IEC958 protocoll that hopefulle someone 
on this list
knows something about. The Left and Right validity bits, and Left, Right 
user
bits, what are suposed to do ?? are they suposed to be 1 or 0 when outputing
AC3/DTS ???

That could be a posible source of the problem, in this patch they are
all turned off.
