Default System Soundcard

thugic · 05-11-2005, 10:57 AM

I have two soundcards, one is the C-Media (integrated and recognized by ALSA as well)
and the other is the Sound Blaster Live! 24 Bit (PCI and also recognized by ALSA) ...
Both cards work good but i wanted tu set the Sound Blaster Live as my default soundcard, so it doesn't use the C-Media one.
I know i can disable it in the BIOS but i need it because it is connected with my Tv Tuner....
So? Is there any way to do this so the system uses the SB Live instead of C-Media?

Any Advice appriciated...TX

You could recompile ALSA without support for the C-Media card. In order for the SB-Live! to work properly you need to use 1.0.9rc3 or later anyway, and 1.0.8 is what comes with Slack 10.1.

actually i've recompiled the kernel to 2.6.11.8 so it supports my SB Live! ...
but nice idea...i'll recompile it without the c-media support

Any other (maybe faster) idea?

hmm...my sblive card has always worked.
(but i don't use the kernel or packages for alsa)

anyways, maybe look into editing your asound.conf

has anyone read this...
MY SB LIVE WORKS VERY WELL!!!!
I ONLY NEED TO SET IT AS DEFAULT SOUNDCARD

See thread:
http://www.linuxquestions.org/questi...highlight=alsa

The soundcard needs to be made card 0 to be default and for alsa to use it.
You must use options in modules.conf to do this

I also have two cards, one integrated and a SB Live Value.
To tell alsa to use the SB card as default I created a .asoundrc file under my home directory with this content (it also allows you to play several sounds at the same time):

Code:

pcm.snd_card {
     type hw
#Select card (like alsamixer -c0 or alsamixer -c1)
#card 0 = AC97 card
#card 0
#card 1 = SB Live Value
     card 1
	 device 0
}

pcm.dmix {
     type dmix
     ipc_key 1024
     slave.pcm "snd_card"
     slave {
          period_time 0
          period_size 1024
          buffer_size 8192
     }

     bindings {
          0 0
          1 1
     }
}

pcm.dsnoop {
     type dsnoop
     ipc_key 2048
     slave.pcm "snd_card"

     bindings {
          0 0
          1 1
     }
}

pcm.duplex {
     type asym
     playback.pcm "dmix"
     capture.pcm "dsnoop"
}

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

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

ctl.dsp0 {
     type plug
     slave.pcm "snd_card"
}

ctl.mixer0 {
     type plug
     slave.pcm "snd_card"
}

Oh and if you want to make it same for all users, I'm quoting this text from http://www.alsa-project.org/alsa-doc...module=Generic (Same link that kodon suggested)

Quote:

Where does asoundrc live?

The asoundrc file is typically installed in a user's home directory

$HOME/.asoundrc

and is called from

/usr/share/alsa/alsa.conf

It is also possible to install a system wide configuration file as

/etc/asound.conf

When an alsa application starts both configuration files are read.
