I purchased a the "Sound Blaster Play! 2" soundcard for my raspberry pi 3. The OS is raspbian jessie.
The audio on my raspberry pi works when I run
$ aplay /usr/share/sounds/alsa/Front_Center.wav -D sysdefault:CARD=S2
But only when I use -D. When I use
$ aplay /usr/share/sounds/alsa/Front_Center.wav
it shows:
aplay: set_params:1239: Channels count non available
I need this for node-speaker.
Here is the output of the ALSA Information script: http://www.alsa-project.org/db/?f=bdefa248fdedb34929d492e65ea941f2af40dcb2

High quality sound with the Raspberry Pi sound card You also don't need tube amplifiers that deliver high quality sound. You can build your private media center using the Raspberry Pi and a sound card, which is necessary in this case, without it it is impossible to play the sounds.
Set default sound card... Open alsa mixer with sudo press F6 or S select your card then type sudo alsactl store. sudo alsamixer sudo alsactl store and OR Setting the default sound device Find your desired card with: cat /proc/asound/cards You will need to be root for this and then create or edit your /etc/asound.
The simplest way to test the sound is to use the speaker-test command. Enter the following to test sound from your default configured audio device. You should hear an alternating sound coming from your left and right speakers. If you're using a USB sound device you first need to check its device id/number.
OK, I found the solution..
My new ~/.asoundrc:
pcm.!default {
type plug
slave {
pcm "hw:0,0"
}
}
ctl.!default {
type hw
card 0
}
instead of
pcm.!default {
type hw
card 0
}
ctl.!default {
type hw
card 0
}
does the magic :)
