Slackintosh user here. I lost sound between kernels 2.6.21 and 2.6.22. The fix was to compile i2c-powermac into the kernel, instead of as a module. This ensured the i2c subsystem was initialized before the snd- aoa module was loaded, which allowed the tas sound device to be detected properly.
Not sure what the underlying issue was (udev?) but this resolved the issue for me. Quick specs: PowerBook5,4 (15" 1.5GHz G4 AlBook) kernel 2.6.24.2 -- No sound in linux-image-2.6.20-8-powerpc G4 https://bugs.launchpad.net/bugs/87652 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
