Summary: spdif hw entry fails to work in multi
Description:
After bug 0000505 was fixed, hw:0,0 only plays to analog devices, and
hw:0,4 to spdif. As one needs output in both, I tried to use .asoundrc ,
and therefore needed to use the "multi" pcm type in order to unite these
two (and then route). This is what I put in .asoundrc
pcm.whole {
type multi
slaves.a.pcm "hw:0,0"
slaves.a.channels 2
slaves.b.pcm "hw:0,4"
slaves.b.channels 2
bindings.0.slave a
bindings.0.channel 0
bindings.1.slave a
bindings.1.channel 1
bindings.2.slave b
bindings.2.channel 0
bindings.3.slave b
bindings.3.channel 1
}
pcm.rt {
type route
slave.pcm "whole"
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
}
The ttable may be wrong - I could not find a sane description anywhere -
but I tried many variants, and besides, playing to "whole" bypasses this.
So here's what I get when playing to "rt" OR to "whole" via alsaplayer :
$ alsaplayer -d whole test.wav

failed to configure output device...trying OSS
then alsaplayer hangs until interrupted.
When I comment out everything related to slave b, "whole" seems to work
(without spdif output, of course). So this seems like a bug in the spdif
device.

Use this:
pcm.rt {
type route
slave.pcm whole
slave.channels 4
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
}
and run with -d rt .

Thanks. This has worked.
A definite must for the FAQ, and a link to this should be present in the
soundcard matrix for i865 - which at this point is not even available.
But I'll refile this as a documentation bug. Please close this one.
Actually, the absence of a *decent* documentation of the route type is
another documentation bug. And, as a professional tech writer I'm
qualified to fix this. I'll write to alsa-devel to offer my services.

Yes, we know the documentation problems :-<
Any help would be appreciated.
BTW, it's possible to implement the analog and spdif simultaneous
output on ICH4 without data duplication. I'll try a hack later.
Anyway, I close this bug now.

Could you try the attached patch? With this patch, the signal to
hw:0,0 will be routed to the spdif, too.
This behavior should be switched by either a module parameter or a
mixer control because someone may want to use analog and SPDIF
separately to play different streams.

The patch has failed.
(I tried to apply it over 1.0.7rc1 plus the bug 505 patches.)
The reason is probably that it's over CVS. Rather than play around with
patches, perhaps you can simply attach intel8x0.c so I could replace the
entire file?
Alternatively I can pull alsa-cvs, of course. Should I do this?
