If so; what did you do to get that sound working ?

To maximize the chance of having a solution for a system exactly to mine, here is the full description of my system:

iMac G3 DV 400Mhz
Slot-in DVD Player
10 Gb HD
ATI Rage 128 (8Mb)
and its the grape one ;-)

haven't used gentoo in a while, but the way i got sound to work was to make sure these modules got loaded.

soundcore
snd-powermac
snd-mixer-oss
snd-seq-oss
snd-pcm-oss
snd

i think those were the main ones, i don't really remember.

hope that helps.

Mkay, thanks.

Alsa would be nicer, but if this works ...

My wife's machine is very similar (G3 iMac, 350MHz, Rage 128, PowerMac2,2) and ALSA worked out the box. I basically did nothing else but follow the Gentoo ALSA guide (except for using the in-kernel drivers instead of alsa-driver). My /etc/modules.d/alsa looks like this:
Code:
alias char-major-116 snd
alias char-major-14 soundcore
alias snd-card-0 snd-powermac
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
options snd cards_limit=1

The rest is just as specified in the guide. Of course, make sure you compile the ALSA stuff in the kernel (I am guessing you know what to do about this one).

Thanks, gonna give it a try asap.

Is it also possible to get the power management working as well as under osX ?
If so, how ?

I have never tried this one. You could of course tweak hard disk spin-down time and the such, but I am not sure whether you can do full power management on the thing.

I just got it working by compiling the powermac alsa drivers in the kernel, and leaving out mac dmasound...
The only problem I have right now, is that xmms plays my songs 2 fast, but I'll figure that out soon ;-)

hello
for the problem with xmms, go to the prefrences, and then in the output plugin part, be sure you have select ALSA then press Configure.

in the new window, go to advanced settings, and set buffert times to 3000 and Period times to 500. it's working for me, i hope it will be good for you too :)




Sorry for my bad english :?

Cheerio :-) works like a charm. All this should work exactly the dame for a Imac 350 or a DV , so I think this topic is solved right now, isn't it?

Does this mean that the alsa drivers do not work as modules? If that's true then I have to recompile my kernel again. :( My next step today will be to get sound working on this iMac.

They do work as modules, I have actually them thus compiled and everything just works. I have also heard stories about ALSA not working compiled into the kernel (they may or may not be true however).

I am using the stock kernel ALSA implementation on many machines (including a circa 2001 CRT iMac which looks similar to the one discussed here) without problems. Some applications work better with output to the OSS emulation instead of directly to the ALSA system, but that's about the only tweak I needed. The only annoyance on the iMac is that the auto-muting of speakers when line-out is used does not work (so that one has to mute the speakers manually in such a case).
