Description J Robert Ray 2004-09-18 23:41:15 UTC

As of gentoo-dev-sources-r14 and alsa-driver 0.9.8, alsa fails to detect the proper sound device in new powerbooks.  The alsa modules load but sound does not come out of the laptop speakers.  Sound can be heard via the headphone jack.

The firmware reports the sound device as "AOAKeylargo."  snd_pmac_detect() in sound/ppc/pmac.c has no code to handle this identifier.

I found this patch on linux-kernel:
http://www.ussg.iu.edu/hypermail/linux/kernel/0406.2/1856.html

After applying the patch to my kernel sources, alsa is functioning correctly.

Is this patch in the mainline kernel tree yet?

Does it apply against the 2.6.8 kernel?

Comment 2 J Robert Ray 2004-09-20 00:42:26 UTC

My bad, the patch is already in 2.6.8.
