Here is what I had to do to get ALSA running on my machine:
YDL stock 2.4.10 kernel (SMP), XF86 4.1, G4 sawtooth w/AGP ATI Rage 128,
Apple Studio Display 17" (using Apple Display Connector).
1. Download alsa-driver-0.9.0beta10.tar.bz2 from:
ftp://ftp.alsa-project.org/pub/driver/alsa-driver-0.9.0beta10.tar.bz2
2. bzip2 -d alsa-driver-0.9.0beta10.tar.bz2
3. tar xvf alsa-driver-0.9.0beta10.tar
4. su -
5. modprobe soundcore
6. cp -R /lib/modules/2.4.10-12a/misc /tmp {for backup}
6. exit
7. cd alsa-driver-0.9.0beta10/cards/ppc
8. vi awacs.c
9. {Delete line 63 that says "#ifdef CONFIG_PMAC_PBOOK"}
10. {Delete line 76 that says "#endif"}
11. Save the file and quit
12. cd ../..
13. ./configure --with-cards=pmac
14. make
15. su -
15. make install
16. modprobe snd-card-pmac
If all the above work, congratulations! All you need to do is add the
following line to /etc/modules.conf (Comment out existing alias sound
lines.).
# ALSA portion
alias char-major-116 snd
options snd snd_major=116 snd_cards_limit=1
alias snd-card-0 snd-card-pmac
options snd-card-pmac snd_index=0
# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-slot-1 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-1-0 snd-mixer-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
Reboot ... you should get no errors in loading the sound module and sound
should work fine in KDE.
If anything goes wrong, you can replace your old /lib/modules/2.4.10-12a/misc
directory with the one from /tmp and you should be OK).
DISCLAIMER: I have ONLY tested this on my machine with the stock YDL kernel.
Your mileage may vary depending on your machine and kernel.
