[Alsa-user] SB Audigy LS SB0310 with no SPDIF sound
|

I have an SB Audigy LS (model SB0310) card installed on my PC:
a dual athlon system with 1Gb ram and 2x120Gb disks configured with some
raid1 and raid0 partitions. The system is dual OS: windows 2000 that I us=
e
very
few times and main os that is a slackware-current synchronized at first
of November 2004.
I compiled a 2.6.9 kernel from scratch and then compiled alsa 1.0.7 libs,=
drivers and utils. I'm using udev.
BTW: I've seen that 2.6.10-rc2 still contained 1.0.6 some days ago...
It seems that I configured all ok for the SB card, also thanks to James
web tips,
but I can get only sound similar to knocks on a microphone if I try to us=
e
SPDIF out.
I have a 5.1 system from Olidata (OLI9918) capable of doing Dolby prologi=
c
and DTS too.
The audio system has 2xrca connection (line), coax connection and optical=
connection.
The connection between the SB0310 and audio system is ok if I
mute the SPDIF and then I enable sound for analog channels in alsamixer
and connect the minijack to line out 1 jack (front left/right) and then
the 2xrca connectors
to the additional line input I have an the audio subsystem.
I can hear the sound and I can play with xine and mplayer and also set Do=
lby
or DTS in dvd menu (but I'm really using it or should be managed only fro=
m
SPDIF???)
I've not a so fine ear, so I can't tell you what I miss from digital out
to analog out... :-)
In windows 2K I'm able to get this configuration working:
through the SPDIF OUT connector and the cable is a minijack 3.5 stereo-->=
2x rca with only one of these connected to the coax plug available on the=
audio system.
In windows it seems to behave correctly:
I can configure it as 5.1 in creative utils and when in stereo I hear the=
front/center
speakers.
Also, I can use an effect available into the audio
system, that splits the sound around the five speakers, so even in
stereo mode I get sound from all the speakers (valid also for Linux confi=
g).
If I play a DVD with dolby or DTS I use passthrough in windvd and so I ca=
n
hear the native dolby from 5.1 speakers (it seems DTS is not working, I
get no sound).

do I miss anything?

When in kde 3.3.1 I play a test sound in control center for sound system,=
I can only hear a sound similar at the one you hear when you knock at a
microphone and nothing else...

Let me know please what I'm missing: perhaps any device file because of
udev...?
And also, if I can be of any help for testing I'm available.
BTW: are there anywhere some test audio files for dolby/dts (a part from
comm dvds)?
Thanks in advance.
Bye,
Gianluca Cecchi
