[Bug 1296373] Re: [PATCH] Fix sound on PowerPC

[Boris Reinhard]

Same problem for me on my ibook G4

Id: PowerBook6,5

Sound Hardware:  via hex dump: 0x26 = so converted device id: 38

Under OSX 10.5.8 it's detected as "Texas Instruments, TAS 3004, 1x Input
(internal mic), 2xoutputs (1xspeakers, 1x headphone jack)"

------------------- 
dmesg:
 3.773496] i2c i2c-3: i2c-powermac: modalias failure on /uni-n at f8000000/i2c at f8001000/cereal at 1c0
-------------------


So is this simply a case of device id's missing and thus not all being listed/ detected or is it something else?

If it is, why is it not yet fixed if patches do already exist? No
offence really just trying to understand this situation.

I've read they (community maintainers) would like to continue supporting
PPC (eg. blog post about looking for more ppc testers) but if something
like that is supposedly an easy fix even for non ppc users, why isn't it
in yet?

What would it take to get this in, I believe the correct expression
would be "upstream"!?

thx in advance

Title:
  [PATCH] Fix sound on PowerPC

Status in “alsa-dkms” package in Ubuntu:
  New
Status in “hw-detect” package in Ubuntu:
  Confirmed

Bug description:
  This patch is one of several needed to fix sound on PowerPC.  The
  wrong modules are loaded/blacklisted on many machines, causing sound
  not to work or worse the fatal "Fixing recursive fault rebooted is
  needed!" bug -
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1066435

  The attached patch incorporates the suggestions in this debian bug
  report https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=650588 , and
  additionally splits off the 'i2s-a' machines which nolonger use
  snd_powermac (at least that is what I understand from this linuxppc-
  dev message -
  http://comments.gmane.org/gmane.linux.ports.ppc.embedded/51204 ).

  It would be excellent if this could make it into Trusty.  I'm going to
  submit another bug on the casper package.
