Dear Kernel People,
Sound fails to work on the PowerBook laptop information on which could be found from http://www.onerussian.com/Linux/bugs/bug.sound/
On 2.6.16-rc1 and got dmasound_pmac: couldn't find a Codec we can handle .... snd: Unknown layout ID 0x52 (and ALSA failed to find any device)
I added 0x52 layout in the list within sound/ppc/pmac.c
case 0x50: case 0x52: case 0x5c: chip->num_freqs = ARRAY_SIZE(tumbler_freqs); chip->model = PMAC_SNAPPER; chip->can_byte_swap = 0; /* FIXME: check this */ chip->control_mask = MASK_IEPC | 0x11;/* disable IEE */ break; after reboot (it was compiled in) and I get dmasound_pmac: couldn't find a Codec we can handle ... snd: can't request rsrc 0 (Sound Control: 0x80000000:80004fff)
I copied pmac.c from 2.6.16-rc2, added 0x52, compiled, reboot and I get just dmasound_pmac: couldn't find a Codec we can handle
and no sound -- I have just
$ ls /dev/{snd,dsp,audio}* ls: /dev/dsp*: No such file or directory ls: /dev/audio*: No such file or directory /dev/sndstat
/dev/snd: seq timer
Pre history: I need to configure Linux in place of OS-X on my chief's laptop. After some struggle I managed to install Ubuntu Dapper which was running their 2.6.15-14. I had few issues: sound kinda was there but nothing was produced audible, video - box freezes under some xorg config as reported elsewhere https://launchpad.net/malone/bugs/30426 and decided to give a try to vanilla kernel so I could also report a bug.
