Raspberry Pi as a Squeezebox Player

SqueezeboxPlayerNotes.txt

# Sound test setup
aplay -L
speaker-test -D sysdefault:CARD=Device 
amixer
# Get out of jail free card
# sudo /etc/init.d/alsa-utils reset 

# alsa configuration
sudo nano /usr/share/alsa/alsa.conf 
/lib/modprobe.d/aliases.conf 

Ok, first delete the file /etc/modprobe.d/alsa-base.conf Raspbian Jessie does not use this config file like Wheezy did.

To find what address your device uses you need to first enter the command aplay -l this shows all audio output devices, and their address. For example, my USB sound card comes up as device 1 in the output which looks like this.
card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA]
  Subdevices: 8/8
  Subdevice #0: subdevice #0
  Subdevice #1: subdevice #1
  Subdevice #2: subdevice #2
  Subdevice #3: subdevice #3
  Subdevice #4: subdevice #4
  Subdevice #5: subdevice #5
  Subdevice #6: subdevice #6
  Subdevice #7: subdevice #7
card 1: Device [USB PnP Sound Device], device 0: USB Audio [USB Audio]
  Subdevices: 0/1
  Subdevice #0: subdevice #0


Now, to set the device to your default card you will need to edit the file /usr/share/alsa/alsa.conf with the command sudo nano /usr/share/alsa/alsa.conf scroll down until you find the lines
defaults.ctl.card 0
defaults.pcm.card 0


and change them to (if your device is also listed as device 1, if not change the 1 to whatever address it was listed at)
defaults.ctl.card 1
defaults.pcm.card 1


Explanation: USB sound cards are registered as card 1 on Raspbian Jessie. On Wheezy they would be registered as card -2 by default and editing /etc/modprobe.d/alsa-base.conf would change that.

I do not know if this next step is necessary but without it my card wouldn't work.

Create and edit the file ~/.asoundrc by using the command sudo nano ~/.asoundrc and change it so that it only reads this:
pcm.!default {
    type hw
    card 1
}

ctl.!default {
    type hw
    card 1
}


Now your default audio out (speakers) and audio in (mic) are your usb device.
