Distorted sound from games?

Postby rebster on Thu Aug 02, 2007 5:23 pm

Hi,

I'm finding that the sound from my games (tuxkart, etc) is sounding distorted: there's a kind of stuttering or static-y quality to the music. These are all 3-d games. It's on a 1.73 ghz Intel core duo laptop with Conexant/Intel high definition sound chip set. I've tried selecting different sound system drivers from Sound prefs, but it doesn't seem to make a difference.

Anybody else heard this or know what causes it?

Best,

SF

Linux Mint is funded by ads and donations.

What video chip is it? Amount of memory, both for video and in general.
It could be that the 3D games takes so much of the resources that sound is suffering

Thank you for responding!!! :D

It's an intel 945 chipset (integrated, with shared memory, of course) and it has 1 GB of system memory. I wonder if they'd run better if I turn off Beryl? Does that eat a lot of memory?

Beryl used about 40 MB on my desktop. I would turn off Beryl - you don't use it in games I suppose :)
Otherwise 945 seems to work ok in most cases

I tried turning off Beryl but it makes no difference; those games still give me static and stuttering sound. I'm frustrated and stumped! :cry:

A temporary solution could be to put the volume control at 100%
Another workaround could be to change ~.asoundrc to read as follows
Code: Select all
pcm.!default {
type plugin
card 0
}

ctl.!default {
type hw
card 0
}

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

pcm.dmixer {
 type dmix
 ipc_key 1024
 slave {
  pcm {
   type hw
   card 0
  }
  rate 44100
  period_time 0
  period_size 2048
  buffer_size 32768
 }
 slowptr 1
}


There seems to be a bug in sdl-mixer
