You still have the snd_powermac stuff built in. Disable it.
| Code: |
CONFIG_SND_POWERMAC=m
CONFIG_SND_POWERMAC_AUTO_DRC=y
|
You should build these into your kernel, it's easier that way, but these should support your mac's sound system.
| Code: |
CONFIG_SND_AOA=m
CONFIG_SND_AOA_FABRIC_LAYOUT=m
CONFIG_SND_AOA_ONYX=m
CONFIG_SND_AOA_TAS=m
CONFIG_SND_AOA_TOONIE=m
CONFIG_SND_AOA_SOUNDBUS=m
CONFIG_SND_AOA_SOUNDBUS_I2S=m
|
You may also want to disable the USB sound device for now. If you want to be sure before you go recompiling the kernel, try to make sure that only the AOA modules are loaded. If you have the Powermac modules loaded, remove both the AOA and the Powermac modules, then reload the AOA modules.

Thanks --- the internal speaker sound now works (or headphones if they be plugged in) but the optical output is still silent. I've kept the sound as modules because I like as minimal a kernel as possible. So now, | lsmod: | Module Size Used by

so some controls cannot be unmuted and some have no volume controls, which I suppose is expected if they are digital controls.
Can you suggest how to get the digital output working ?

I've left a few lines before and after the sound stuff so you can see that all the sound-related output is there.
It does occur to me that if I knew what the digital sound device hardware was, I could probably enable that hardware by name, as there is support for quite a lot of sound hardware, but none of it marked "This is the digital HW on a G5".

Could someone who is dual-booting MacOS have a look at the hardware information dialog and tell me what the digital audio hardware is called: chipset, manufacturer etc.
My MacOS X DVD is physically damaged and I'm unable to install MacOS X myself.

All of the Apple G5's use AOA. There's nothing else to find.
TAS might support the digital I/O, but it's certainly possible that nobody has ever tried it before. What machine is this specifically (cat /proc/cpuinfo | grep -i machine) ? I have heard of digital being used on machines with ONYX codec support.
On my G5, I get:
| Code: |
snd-aoa-codec-onyx: found pcm3052
snd-aoa-codec-onyx: attached to onyx codec via i2c
snd-aoa-codec-onyx: created and attached onyx instance
|
And a "digital" control in alsamixer.

and what is curious about that messages log is that snd-aoa-codec-onyx did occur during one boot, three days ago, but not since. I cannot explain that. In any case, it looks like my machine has -tas hardware rather than -onyx. I must confess to my ignorance about sound hardware. I thought a codec was a sound encoding format like .wav or .au but it seems to mean the hardware interface.

I thought so too, but apparently the term is used in a wider manner.

Your sound layout id allows tas and onyx, at least so it seems. Toonie is not tried, again due to the layout id.
It would be much easier to look in Mac OS X' System Profiler which CODEC it uses. It may well be TAS and Onyx that is needed.
My experience is limited to
- PowerMac3,6 aka Power Mac G4 “Mirrored Drive Doors” (MDD) – which uses aoa-codec-tas, and Mac OS X reports a Texas Instruments TAS3004 CODEC
- and a PowerMac11,2 aka Power Mac G5 “Late 2005” – which uses aoa-codec-onyx, Mac OS X reports CODEC Burr Brown PCM3052 “Onyx” and Crystal Semiconductor CS84xx “Topaz”.
I haven't tried the digital out on my G5, and in lack of a suitable device to be connected to it I probably never will.
One thing that I would try is to remove aoa-codec-tas and let there be only aoa-codec-onyx and see what this will do. Maybe onyx cannot be used because tas is in the way.
If nothing works, I'd contact one of the developers for ALSA PowerMac/AOA, preferrably Johannes Berg who wrote ALSA AOA.
- http://bugtrack.alsa-project.org/main/index.php/Main_Page
- http://bugtrack.alsa-project.org/main/index.php/Matrix:Module-powermac
- http://bugtrack.alsa-project.org/main/index.php/Matrix:Module-aoa
Also, there is a Wiki that may be able to help.
- http://alsa.opensrc.org/index.php/Main_Page
I hope you'll get it working! Good luck!
Cheers, A.
EDIT – APPENDED:
Looking at /usr/src/linux-2.6.34-gentoo/sound/aoa/fabrics/layout.c I cannot find a PowerMac7,2, so maybe the author Johannes Berg had no chance yet to include and test it. You can also see that for my G5 PowerMac11,2 (in layout.c listed as “Quad PoweMac”) onyx is responsible for Analog In+Out and Digital Out, and topaz (which is included in aoa-codec-onyx) is responsible for Digital In.
There is something I wrote a while ago:
- http://alsa.opensrc.org/index.php/Aoa
What is your output of:
find /proc/device-tree/ -name layout-id | xargs hexdump -e '1/4 "0x%x\n"'
Search for these layout ids in /usr/src/linux-2.6.34-gentoo/sound/aoa/fabrics/layout.c to see if it gives any clues.
Cheers, A. |

That find command gave 0x24 as the only output, which is 36 decimal, which is the tas codec. Only onyx and topaz include digital output. So it seems that PowerMac7,2 is not supported yet. I've emailed Johannes so I'll await his reply.
