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.
