[Bourbon (old)]

Im runing ubuntu 7.10 gutsy I installed ut with the zip files and the install script. But in game i get even just loading up the main screen i get a sound lage of about 1/2 a second or so. Ive tried tweaking cl_mixahead but it dosent seam to help. Is there any cvrs or anything to tweak sound settings?. I also have alsa setup and runing to do mixing could something be screwy there? I dont seam to get sound lag in movies or music. I hope this can be fixed because im getting 90 fps in ubuntu and only 60 in win xp.

well you and me both but I also get a mouse lag issue as well. Hope someone could help us out!

Please provide us your cat /proc/asound/cards

cat /proc/asound/cards spits out:

also to get sound to work threw my head set i had to create a asound.conf which reads as fallows:

pcm.my_card {
  type hw
  card 1
   #mmap_emulation true
}

pcm.dmixed {
  type dmix
  ipc_key 1024
  #  ipc_key_add_uid false   # let multiple users share
  #  ipc_perm 0666           # IPC permissions for multi user sharing (octal, default 0600)
  slave {
  pcm "my_card"
  #   rate 48000
  #   period_size 512
  }
}

pcm.dsnooped {
  type dsnoop
  ipc_key 2048
  slave {
  pcm "my_card"
  #   rate 48000
  #   period_size 128
  }
}

pcm.asymed {
  type asym
  playback.pcm "dmixed"
  capture.pcm "dsnooped"
}

pcm.pasymed {
  type plug
  slave.pcm "asymed"
}

pcm.dsp0 {
  type plug
  slave.pcm "dmixer"
}

pcm.!default {
  type plug
  slave.pcm "asymed"
}

some thing could be wrong in my config file as i am a come pleat noob to setting up mixing and the like. i have been trying a lot of diferent things to fix this issue but none have worked i recently tried s_useopenal but that didnt work. This is just weird as like i said before movies and music do not lag at all.

My suggestion: Dont use dmix plugins with gaming. It adds horrible latency delays in the sound. Maybe unless you run real-time Linux kernel with jackd, but i dunno, i havent tried that .. yet. Might be funny to try that out on a cold rainy day...

But i'm guessing you are doing all that because your USB headset is on the secondary device (even tho it's set up as default for alsa). What you could try is to tell the ca0106 module NOT to take the primary index number. So the USB audio becomes the default OSS device.

Look in /etc/modprobe.d/alsa-base and add:

options snd-ca0106 index=-2

[Bourbon (old)]

I added

options snd-ca0106 index=-2

to the /etc/modprobe.d/alsa-base rebotted and lost all sound threw my headset.

i dont know if this helps but when i do a lsmod |grep snd i get:

shouldnt all these be pointing to 1? as that is my default sound device? also i dont know if this will help narrow down the problem but the intro scene music is chopy at best but all other game sounds are normal and fine just lag half a second behind.

The index=-2 trick works for me on a system with onboard audio and a pci audio device (SB); but your is an usb so that might be different (did you booted with the USB device already attached?).
From your lsmod listing, the usb audio device module seems to be loaded. You should also check or the device is actually available by typing:

cat /proc/asound/cards

The delay you have is caused by having the audio stream that needs to be processed first through the ALSA dmix plugin.

[Bourbon (old)]

cat /proc/asound/cards

says my usb headset is there and is default.
I do boot with it attached so no hot pluging or any thing to break there.
I figured it was something with alsa would it be a good idea to try using arts or some outher audio mixer thingy?Is there a way to not use the dmixer plug and still achieve mixing(i assume that's where arts or jack comes in to play)?

Also would it be possible to use my sound card for hardware mixing and then some how clone it or slave it to my usb headset and do it that way?
