Hi Johannes
Thanks for the update .. :)
I loaded the new drivers, and they work, as it seems. In the end it
will probably need a bit more use of this driver before i can give a
reliable test report ... :)
Below a few first notes ..

Hey,
Currently snd-aoa is known to work on the following machines:
* PowerBook5,8
I use snd-aoa on the latter
People with those machines are encouraged to use and stress-test it,
I compiled/installed your (old) snd-aoa files at about last (Tuesday)
night , and got these errors when re-booting the machine today:
-------------------------

This error seems to be *gone* after updating ('git pull') snd-aoa,
compiling and installing it at about 16:00 UTC today (Wednesday)...

Notes:
1:
I removed snd-powermac from /etc/modules to prevent the module from
being loaded when booting ... only today .. Sound still works ... :)
2:
Took me some reboots/'alsactl store' to have sound switched on
automatically after logging in to KDE ... not being sure what was
going on ..
3:
I have a kmix Volume slider now ... this is new on *this* kmix applet
(i.e. the one I have to load via Multimedia --> KMix from the KDE
kicker)
So: Nice ... is this the solution you like, too ? ... ;) ..
4:
I can hear two sound files at the same time: Didn't work at the first
try. I then installed again /etc/asound.conf, that I copied from my
old ti-IV-Book (Not being sure tho' whether this really is such a good
idea .... :

Ooops: Alsaplayer just disappeared while playing somem Internet radio
station:
/var/log/kern.log from about the time of the crash:
May 17 23:34:11 debby1-6 kernel: [15962.091766] i2sbus: stop/suspend
[nothing more, as it seems .. Sorry]
No problem restarting alsa-player after this little crash .. :)
Now, when you boot, mac-io is already built-in so provides the i2s
device, which my i2sbus module binds to. Since udev synthesizes events,
i2sbus gets loaded automatically. Now, i2sbus creates uevents on its
own, with the layout number given as the MODALIAS. Hence, the layout
fabric module is loaded because it has an alias for all the layouts it
handles, and it in turn requests all the codec modules that it requires.
Also, this means that 'modprobe i2sbus' will suffice to get the driver
up and running without a reboot,
... didn't try this so far, but I'll keep that in mind for
/etc/modules ... :)
The problem I had so far after installing the new snd-aoa drivers was
to first unload them (before reloading) without the need to reboot
... it seems the KDE panel (kicker) is using the drivers, thus
preventing them from being unloadable ... I'll see into that later on
...
Just in case it helps:
