I have the same problem on my PowerMac G4. After reading the note from Dave Vasilevsky, I also checked the status in the snd_pmac_pcm_update function, and it seems that the failing DMA transfer has the status DEAD. I've then checked the old OSS powermac sound driver in sound/oss/dmasound/dmasound_awacs.c (which used to work with newer kernels) - and yes, this driver handles DEAD DMA transfers!
So I've spent some time porting the DEAD DMA transfer handling code from the old driver to the new one - and now sound it working for me again with kernels 2.6.22 / Ubuntu 7.10. I've attached my patch, would be nice if other users here could try it out, too! ** Attachment added: "Patch for broken sound on G4 PowerMac" http://launchpadlibrarian.net/11311439/pmac.c.diff -- 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
