Sound drivers for newer machines: need help

Sound drivers for newer machines: need help

[Benjamin Herrenschmidt]

Hi !

If you have a newer machine, that is a machine released on or after
2002, can you please send me the output of:

echo `cat /proc/device-tree/model`

and

for i in `find /proc/device-tree -name layout-id -print`; do echo $i && hexdump -n4 $i; done

If the later returns nothing, it's fine, just tell me.

I'm especially interested in the various models of G5 based machines. It
seems apple is having all sorts of very different sound HW setups on
those machines, and I'm trying to figure out exactly what is where based
on those infos and the darwin sources.

Ben.

Hi Ben,

and the second command prints nothing.

Why limit this to new hardware, though?  Why not modularize the pmac ALSA
tree and completely fix all previous hardware variants as well?

Btw, not sound-related but nonetheless a bug in the device tree:

/proc/device-tree/psuedo-hid

That wouldn't be a typo now, would it?

Yep, returns nothing.

Hi Ben, this is a Powerbook 12" post feb-2005.

As you know sound does not work, the card seems to be recognized and the
module "snd_powermac" is loaded, sound-applications (rhythmbox, xmms,
bmp, totem, etc...) work but nothing can't be heard:

If it is, I suspect it's in your version of the firmware. That isn't
added by the kernel. Here's mine:

dr-xr-xr-x  5 root root 0 Apr  9 09:17 /proc/device-tree/pseudo-hid/

And in OSX, ioreg lists a top level node of pseudo-hid as well. These
are PowerMac7,2 and PowerBook5,2 respectively.

For your information, in case this helps...

I am using ALSA and it appears to work except that only one program can
access the sound hardware at a time (so is just like OSS :-)).  If I am
playing music in XMMS and then try to aplay a .wav file, it will hang
until XMMS is closed for example.

The trick of altering the HZ of mp3 plug-in to remove the choppiness
doesn't seem to work for all mp3 files (thought does for the vast
majority).

Many thanks for looking into this (and all the other work you do --
sleep support, for example, has been *incredibly* useful)!

best regards,

It is a typo by Apple. It is the name in the firmware of my
PowerMacG4 466 (PowerMac3,4) under the OF prompt too 
(psuedo-hid and psuedo-sound). 

OTOH in my Pismo (PowerBook3,1) these same name are spelled 
correctly, despite the fact that it is older (but it has had 
at least one firmware upgrade while the G4 has none AFAIR).

/proc/device-tree keeps the names given by OF and only adds 
a few of its own, "linux,phandle" mostly.

Which is what I am doing, I just need some more infos about new hardware
because the HW setup done by Apple on those is fairly confusing.

Might be but nobody cares about this one anyway.

If you set apps like xmms to actually use alsa output, you can have
mixing but for that, you have to enable the dmix plugin in your alsa
config. Look for infos about that on this list archive.

I am not sure if my Powerbook was released after 2002, but the date(the
