Sound Card Setting on Raspbian Jessie

[G10DRAS]

Here is doc on Advanced Linux Sound Architecture (see: Set the default sound card)

https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture

 

In Raspbian Jessie, File /etc/modprobe.d/alsa-base.conf is removed. You need to set default in /usr/share/alsa/alsa.conf

 

All the relevant text is in that file just run

sudo nano /usr/share/alsa/alsa.conf

change the default sound card to 1 or whatever you prefer obviously 0 is default so not that I also deleted the # from the line that says...

# load card-specific configuration files (on request)

and now I have the sound coming from my audio card running Debian 8 Jessie on RPi2B.

 

sudo nano /usr/share/alsa/alsa.conf

defaults.ctl.card 0

defaults.pcm.card 0

# load card-specific configuration files (on request)

Change To

defaults.ctl.card 1

defaults.pcm.card 1

load card-specific configuration files (on request)

OR

Just Edit/Create a file called /etc/asound.conf or ~/.asoundrc and insert this lines:

sudo nano /etc/asound.conf

pcm.!default {

    type hw

    card 1

}

ctl.!default {

     type hw

     card 1

}

OR

Just Edit/Create a file called /etc/modprobe.d/alsa-base.conf

and insert this lines:

sudo nano /etc/modprobe.d/alsa-base.conf

# This sets the index value of the cards but doesn't reorder.

options snd_usb_audio index=0

options snd_bcm2835 index=1

# Does the reordering.

options snd slots=snd_usb_audio,snd_bcm2835

 

Reboot the device,  and confirm the change using command
cat /proc/asound/cards
