Subject: Surround sound problem with CS46xx
Date: Wed, 06 Jun 2007 22:51:53 +0300	[thread overview]
Message-ID: <46671059.7050003@gmail.com> (raw)

Hi to everybody,


I am kind of new in linux and to alsa and I am facing a problem with the 
setup for 5.1 surround sound with my sound card Hercules Fortissimo III, 
recognized  having the chip cs46xx. I have managed to enable surround 
sound by creating a .asounrc file with the followings


pcm.!default {
  type plug
  slave.pcm "surround51"
  slave.channels 6
  route_policy duplicate
}

The problem is that I am facing weird cpu load spikes (sometimes isn't 
just spikes, but just 99% usage for a long time!) even when just playing 
a normal mp3 file at 128Kbps. This is happening when playing with 
various players (totem,rhythbox,vlc). Also the sound has cracklings or 
there is a delay between the front and the rear speakers. i have send 
this email to alsa-users too, but since there wasn't anyone to propose a 
workaround I was adviced to also send it to alsa-devel.  I am using the 
distro ubuntu 7.04 with the default alsa libraries version 1.0.13ubuntu5.

So, if anyone has any idea plz give me a hint, cause I am stuck with it 
about two weeks now, without having any clue to proceed with!!!





PS. If any other information or command output is necessary to help me, 
tell me so.
