Summary: cs46xx DTS pass through works, but AC3/Dolby Digital
does not
Description:
Dear Alsa developers.
I have an interesting situation with my Terratec XFire 1024 and Sony
STR-DB930 external amplifier.
I have a dual boot system. When I use Windows and Windows DVD players,
digital pass-through sound works perfectly. When I switch to Linux FC4 +
Alsa + Xine, only DTS pass-though sound works. In particular, when playing
a typical DVD that uses Dolby Digital sound by default, the amplifier
recognizes that it is receiving Dolby Digital signal (Sony STD DB-930
front panel shows text "Dolby Digital [3/2]", and all the apropriate
status lights are turned on, too), but no sound comes out. Likewise, no
DVD intro sounds that play before and during DVD menus can be heard (but
Sony STD DB-930 front panel shows for example text "Dolby Digital [2/0]").
There is no humming, rattling, popping, or some other artifact sounds
either, just silence.
If I on the other hand select a DTS sound track using Xine DVD menu
functions, the aplifier recognizes that it is now receiving DTS signal
(font panel shows "DTS [3/2]"), and sound plays as it should!
If I configure Xine to do the decoding and output normal stereo sound,
that works too, but without the benefits of surround sound, of course.
It would therefore seem that current ALSA cs46xx driver can almost but not
quite output Dolby Digital sound in a format that the Sony STR-DB930
amplifier recognizes. One the other hand, DTS signal comes through ok. I
hope that these observations will propably limit the number of locations
where the problem may be.
I would also point out that the amplifier status display reacts correctly
to changes in signal type. This propably proves that at least something
does indeed come though correctly. Finally, the fact that everything works
perfectly with Windows drivers shows that the card and amplifier can work
together.
I have also tried to randomly change the control values in Xine iec958
control string (the audio.device.alsa_passthrough_device parameter that
has the default value of "iec958:AES0=0x6,AES1=0x82,AES2=0x0,AES3=0x2) but
without any effect.
I have also tried various control values with 'iecset' utility, but again
without any effect.
I have no custom .asoundrc settings in place.
I have to admit that I have not tried other recent players than Xine
0.99.4-1.2.fc4 yet, mainly because latest mplayer current crashes and I
have had some trouble compiling it, too. However, I have observed the same
problem earlier with older Xine and mplayer version is some older Linux
distribution (and exactly the same hardware).
I would be very thankfull for any advice. I would also be happy to run any
additional tests you might consider usefull.

Maybe some administrator could fix the duplicate relationship link?

Is there anything I can do to help? I'm not AC3/cs46xx expert, but I can

Unfortunately, I do not understand the suggested resolution for issue
0001359 by 'tiwai'. In particular, I can not see how issue 0000542 could
be a duplicate for this issue 0001359 I reported: 0000542 was a
compilation problem, and it conserns an old kernel and Alsa version. This
old issue should also be already fixed in the latest kernel and Alsa
versions I'm using. Furthermore, issue 0001359 was also not a compilation
problem at all, but about Alsa cs46xx driver pass-through working almost
but not quite with AC3/Dolby Digital sound tracks.
Could it be that the issue 0001359 is a duplication of some other issue
than 0000542, and there just were a simple typing error when these issues
were linked? In any case, I would very much appreciate some verification
or elaboration about the suggested resolution, if possible.

I have also tried to randomly change the control values in Xine iec958

has the default value of "iec958:AES0=0x6,AES1=0x82,AES2=0x0,AES3=0x2) but

I have also tried various control values with 'iecset' utility, but again

I have no custom .asoundrc settings in place.
I have to admit that I have not tried other recent players than Xine
0.99.4-1.2.fc4 yet, mainly because latest mplayer current crashes and I
have had some trouble compiling it, too. However, I have observed the same
problem earlier with older Xine and mplayer version is some older Linux

Summary: cs46xx DTS pass through works, but AC3/Dolby Digital
does not
Description:
Dear Alsa developers.
I have an interesting situation with my Terratec XFire 1024 and Sony
STR-DB930 external amplifier.
I have a dual boot system. When I use Windows and Windows DVD players,
digital pass-through sound works perfectly. When I switch to Linux FC4 +
Alsa + Xine, only DTS pass-though sound works. In particular, when playing
a typical DVD that uses Dolby Digital sound by default, the amplifier
recognizes that it is receiving Dolby Digital signal (Sony STD DB-930
front panel shows text "Dolby Digital [3/2]", and all the apropriate
status lights are turned on, too), but no sound comes out. Likewise, no
DVD intro sounds that play before and during DVD menus can be heard (but
Sony STD DB-930 front panel shows for example text "Dolby Digital [2/0]").
There is no humming, rattling, popping, or some other artifact sounds
either, just silence.
If I on the other hand select a DTS sound track using Xine DVD menu
functions, the aplifier recognizes that it is now receiving DTS signal
(font panel shows "DTS [3/2]"), and sound plays as it should!
If I configure Xine to do the decoding and output normal stereo sound,
that works too, but without the benefits of surround sound, of course.
It would therefore seem that current ALSA cs46xx driver can almost but not
quite output Dolby Digital sound in a format that the Sony STR-DB930
amplifier recognizes. One the other hand, DTS signal comes through ok. I
hope that these observations will propably limit the number of locations
where the problem may be.
I would also point out that the amplifier status display reacts correctly
to changes in signal type. This propably proves that at least something
does indeed come though correctly. Finally, the fact that everything works
perfectly with Windows drivers shows that the card and amplifier can work
together.
I have also tried to randomly change the control values in Xine iec958
control string (the audio.device.alsa_passthrough_device parameter that
has the default value of "iec958:AES0=0x6,AES1=0x82,AES2=0x0,AES3=0x2) but
without any effect.
I have also tried various control values with 'iecset' utility, but again
without any effect.
I have no custom .asoundrc settings in place.
I have to admit that I have not tried other recent players than Xine
0.99.4-1.2.fc4 yet, mainly because latest mplayer current crashes and I
have had some trouble compiling it, too. However, I have observed the same
problem earlier with older Xine and mplayer version is some older Linux
distribution (and exactly the same hardware).
I would be very thankfull for any advice. I would also be happy to run any
additional tests you might consider usefull.
