Note that if you're going to compil nun geht der alsamixer 
mit den *seq* nun auch der sequenzer :) snd_cs46xx 93768 0 snd_rawmidi 25572 1 snd_cs46xx snd_seq_device 9992 1 snd_rawmidi snd_ac97_codec 71300 1 snd_cs46xx snd_pcm 89284 1 snd_cs46xx snd_timer 26372 1 snd_pcm snd 53028 6 snd_cs46xx,snd_rawmidi,snd_seq_device,snd_ac97_codec,snd_pcm,snd_timer soundcore 9376 1 snd snd_page_alloc 12872 2 snd_cs46xx,snd_pcm snd_seq_oss 38720 0 snd_seq_midi 10592 0 snd_seq_midi_event 8768 2 snd_seq_oss,snd_seq_midi snd_seq 57616 5 snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_rawmidi 25572 2 snd_seq_midi,snd_cs46xx snd_seq_device 9992 4 snd_seq_oss,snd_seq_midi,snd_seq,snd_rawmidi snd_timer 26372 2 snd_seq,snd_pcm snd 53028 11 snd_mixer_oss,snd_seq_oss,snd_seq_midi,snd_seq_midi_event,snd_seq,snd_cs46xx,snd_rawmidi,snd_seq_device,snd_ac97_codec,snd_pcm,snd_timer
Next is the tricky part of getting the Alsa sound drivers to work correctly, here are some usefull commands that may be of help:
# /usr/bin/esd & # /usr/bin/esdctl unlock # esdctl off1 # artsdsp -m quake3
slightcrazed of http://www.linuxquestions.org/questions/showthread.php?threadid=121619 says that to play in other than root mode open the sound permissions with:
- # chmod 666 /dev/dsp* # chmod 666 /dev/mixer* # chmod 666 /dev/pcm*
I add to these commands this with:
- # chmod a+rw /dev/sequencer # ls -l /dev/dsp
Here are some strange, but probaly nessisary commands:
- # lsmod | grep snd # lsof | grep dsp # lsmod | grep sound # lsmod | grep snd # lsof | grep dsp # modprobe snd-via82xx # modprobe snd-pcm-oss # modprobe snd-mixer-oss # modprobe snd-seq-oss
I made a file called .soundrc and placed it in the /root/ directory, although I don't know why, here are the lines in it:
- pcm.!default { type hw card 0 } ctl.!default { type hw card 0 }
I checked the Alsa ability to play sounds with:
- # aplay -D default /opt/kde3/share/sounds/pop.wav # ecasound -i /opt/kde3/share/sounds/pop.wav -o alsa.hw:0,0
The most difficult problem to find was that in the /etc/sysconfig/sound file the line LOAD_SEQUENCER="yes" needs to be changed to LOAD_SEQUENCER="no".
Another catch was when checking /dev/sndstat with the command:
- # cat /dev/sndstat
it did not exist. These commands fixed the problem. First find "sndstat" and check it:
- # cat /proc/asound/oss/sndstat
Next link to it:
- # rm /dev/sndstat # ln -s /proc/asound/oss/sndstat /dev/sndstat # cat /dev/sndstat
These lines may be needed each time quake3 is run, so maybe a script would work better, like:
- #use if alsa is not already started in xwindows# /etc/init.d/alsa start killall artsd; killall esd
echo "quake3.x86 0 0 direct" > /proc/asound/card0/pcm0p/oss echo "quake3.x86 0 0 disable" > /proc/asound/card0/pcm0c/oss /usr/local/games/quake3/quake3
