Ok, I continue to feed this self-made thread, in the hope that anyone
gives suggestions/clarifications.
So now I have also installed F12 x86_64 into another partition of the
same system, so that it coexists with F11 x86_64 and windows XP
Some progress, probably due to the alsa version into the kernel
(2.6.31.9-174.fc12 vs 2.6.30.10-105.fc11).
I formerly found another thread opened in 2009 in alsa-user or
alsa-devel where this command was referred as working through optical:
aplay -D iec958:CARD=SB dts_file.wav
- In my F11 this command gives no signal through the receiver, so I
didn't mention it
- But now in my F12 this commands succeeds!
My receiver has:
3 leds controlled by a button named "mode": digital, pro logic, st
3 leds controlled by a button named "input": line, optical, coaxial
When I set input button to optical and play the sample dts file with
the command above in F12, the mode led automatically switches to
digital, and a led named "lock" blinks and I get sound through
optical... hurra!
Also, the other leds referring the 5 channels switch on and I hear the
sound through all of the 5 speakers
This happens with pulseaudio running, so that it is not the problem....
Now the help required at this point: mplayer
mplayer -ao alsa:spdif with this dts sample file gives no sound in F11
while it "almost" works in F12.
I use almost because when I play the same file as before, the mode led
doesn't go to "digital", but to "st".
I can then press the mode button having it switch to "pro logic" and
again to "st", but not to "digital"
And the sound is not the same as with the aplay command.
Is there an option to give to mplayer to have it use the device that
in aplay is "iec958:CARD=SB"?
It seems I didn't find the right combination.
Or if it is possible to create an entry in asound.conf like
pcm.viaspdif {
something
}
and use then mplayer with a commad such as
mplayer -ao alsa:viaspdif
Thanks in advance to anyone available to give any light....
