Can't get sound recognized in Powermac G4 M8840LL/A

I can't get my sound recognized in my powermac g4 machine. I installed ALSA in the kernel but see nothing when I "dmesg". Any ideas?

Follow this guide:
http://www.gentoo.org/doc/en/gentoo-ppc-faq.xml#sound

If it still doesn't work, please paste in the output of dmesg on boot

Hi,

I followed with no success. Here's my dmesg output:

Are you sure you're booting the right kernel?

What does the sound section of your kernel config look like?

nuzzy · Post by **nuzzy** » Tue Oct 31, 2006 5:09 pm

I'm using 2.6.18-gentoo-r1

Here's what's in my .config:

davidgurvich · Post by **davidgurvich** » Tue Oct 31, 2006 5:29 pm

I see you have sound as a module. I had an issue where the module loaded after alsa started. You could get around that by compiling the sound driver into the kernel.

Thanks, but I tried this and still a no-go

JoseJX · Post by **JoseJX** » Fri Nov 03, 2006 11:12 pm

Please post the whole sound section so we can figure out what you're missing. Also, did you make sure to enable i2c support as it says in the FAQ? It's required for sound support.

nuzzy · Post by **nuzzy** » Tue Nov 07, 2006 7:13 pm

Hi Jose,

I enabled the i2c support. Which sound section would you like me to post?

JoseJX · Post by **JoseJX** » Tue Nov 07, 2006 7:24 pm

Everything between:

#
# Sound

and

CONFIG_DMASOUND_PMAC=y
CONFIG_DMASOUND=y

Basically, if you enable the OSS driver, ALSA will not work. Please try removing these as it says in the FAQ and see if that helps.

I'm also not sure if that machine has a fabric/layout as needed by snd-aoa. I'd try the regular PowerMac ALSA driver first.

salmonix · Post by **salmonix** » Mon Nov 20, 2006 7:58 pm

I have followed the thread for i have the same problem with my Tibook 500Mhz.
I have ALSA in-kernel, no OSS, PowerMac DMA in-kernel, ALSA PowerMac devices in-kernel, and I2C support in-kernel. Alsa finds no snd, no soundcard etc.
Unfortunately i've been able to collect no data about the identity of this Tibook's soundcard. Should i set everything else in-module?

JoseJX · Post by **JoseJX** » Mon Nov 20, 2006 8:27 pm

You followed the FAQ? I have the same TiBook and the in kernel ALSA PowerMac drivers work fine. Do not enable the PowerMAC DMA driver, it's the OSS driver. From the FAQ: "Note: Please make sure that PowerMac DMA sound support is turned off, otherwise the ALSA module will not be able to load." If you still can't get it to work, please post the sound section of your kernel config.

salmonix · Post by **salmonix** » Tue Nov 21, 2006 7:48 pm

Right, DMA is on. OK., I must learn to reag again.
