Dear all
Here is the alsa section of the FAQ about Linux version of doom3:
This FAQ says about amd64 system:
"on amd64 systems you may need to get the snd-ioctl32 module loaded in "
What does it mean? I don't understand the meaning of this sentence (excuse me but english is not my mother tongue). What is the snd-ioctl32 module ?
Thanks in advance,
Best regards,
Etienne

Dear Eric,
I've modified the file DoomConfig.cfg as you indicate, and there is no sound
at all when I switch to alsa. The message I get is:
------------- Warnings ---------------
during DOOM 3 initialization...
WARNING: idPort::SendPacket: bad address type NA_BAD - ignored
WARNING: sound subsystem disabled
2 warnings
When I specify seta s_alsa_pcm "default" in the config file, I get very noisy
sounds, and the messages in the shell are:
....
idAudioHardwareALSA::Write: 4096 frames overflowed and dropped
snd_pcm_writei failed: Resource temporarily unavailable
snd_pcm_writei short write: 940 out of 1024
snd_pcm_writei short write: 1880 out of 2048
snd_pcm_writei short write: 940 out of 1024
idAudioHardwareALSA::Write: 4096 frames overflowed and dropped
snd_pcm_writei short write: 1880 out of 2048
snd_pcm_writei short write: 940 out of 1024
snd_pcm_writei short write: 940 out of 1024

idAudioHardwareALSA::Write: 4096 frames overflowed and dropped
snd_pcm_writei failed: Resource temporarily unavailable
snd_pcm_writei short write: 940 out of 1024
....
I precise:
I've got arts running using alsa output, but I specify it to suspend if
inactive during 30 secondes. I tested sounds in doom3 with and without arts
launched: it changes nothing.
Also when running doom3, the cpu frequency is max (2.2 GHz), so I don't think
that my problem would come from bad configured cpuscaling...
I don't know what to do to have good perfs with good sounds. (Remember if I
switch to oss backend, perfs are low and sounds are just acceptable).
Best regards,
Etienne Imguimbert
