Has anyone explored sound on the G4 towers? I understand they use an 12c-based sound card similar to the iBook2.
Texas, aka Tumbler. AFAIK exact same chipset as the iBook2's are outfitted with.
I tried the iBook sound hack on the G4 tower to see what happens. It appears to be partly successful. The sound driver loads and registers the deq, but when I try to do anything that writes to the device I get silence and "can't locate module..." errors in the syslog. Below are the details. I'm guessing the hack is partly successful but the "tumbler" is failing.
Looking at the messages, it looks like everything is loading and initing correctly. The messages below, however:
Oct 19 20:54:38 garuda modprobe: modprobe: Can't locate module sound-slot-1 Oct 19 20:54:38 garuda modprobe: modprobe: Can't locate module sound-service-1-0
seem to indicate something is trying to open /dev/mixer1 instead of /dev/mixer0 (which /dev/mixer should either be a symlink pointing to, or a dev node with the same major/minor numbers). What does your /dev/mixer look like? It shuld be major 14, minor 0. Check /usr/src/linux/Documentation/devices.txt for all the major/minor numbers for devices (including sound devices). In other words, the Texas chip is probably functioning fine - you have to tell it to do something now, though...
