[SOLVED] Set default sound card

ursusca · 03-19-2010, 03:21 PM

Hello there!

I have ASUS M4A78-E motherboard. I've disabled Onboard sound card (VIA VT1708S) and installed Audigy sound card (c-media sb 8738 5.1 channel (CMI8738/PCI-6ch-LX)). My system detects now two audio devices.

Code:

$lspci -v
01:05.1 Audio device: ATI Technologies Inc RS780 Azalia controller
   Subsystem: ATI Technologies Inc RS780 Azalia controller
   Flags: bus master, fast devsel, latency 0, IRQ 19
   Memory at fbdfc000 (32-bit, non-prefetchable) [size=16K]
   Capabilities: [50] Power Management version 3
   Capabilities: [a0] MSI: Enable- Count=1/1 Maskable- 64bit+
   Kernel driver in use: HDA Intel
   Kernel modules: snd-hda-intel

04:05.0 Multimedia audio controller: Creative Labs CA0106 Soundblaster
   Subsystem: Creative Labs SB0570 [SB Audigy SE]
   Flags: bus master, medium devsel, latency 64, IRQ 20
   I/O ports at ec00 [size=32]
   Capabilities: [dc] Power Management version 2
   Kernel driver in use: CA0106
   Kernel modules: snd-ca0106

ATI HDMI (part of the gpu) and my Audigy sound card. ATI HDMI is a dafault sound card now

Code:

cat /proc/asound/cards
 0 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xfbdfc000 irq 19
 1 [CA0106         ]: CA0106 - CA0106
                      Audigy SE [SB0570] at 0xec00 irq 20

I've disabled HDA ATI HDMI in Gnome sound preference. How can I change default sound card on Audigy?

Thanks,

There are a couple different ways to do this;
.asoundrc
http://alsa.opensrc.org/.asoundrc
depending on your baselayout version
/etc/modules.d/alsa or
/etc/modprobe.d/alsa.conf
http://groups.google.com/group/linux...bdddda5b1f1b9f
http://alsa.opensrc.org/index.php/Mu...an_GNU.2FLinux
/etc/asound.conf

Thank you comprookie2000!

I'm using baselayout version 1.

Code:

# emerge -p baselayout

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] sys-apps/baselayout-1.12.13

I've added this lines to my /etc/modprobe.d/alsa.conf file

Code:

# --- END: Generated by ALSACONF, do not edit. ---
#set default sound card
options snd-ca0106 index=0
alias snd-card-1 snd-hda-intel
options snd-hda-intel index=1
options snd cards_limit=2

Code:

# cat /etc/modprobe.d/alsa.conf 
# Alsa kernel modules' configuration file.

# ALSA portion
# OSS/Free portion

##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
