RPI 3 - ALSA configuration

RPI 3 - ALSA configuration
RPi 3 with latest Xbian release.

What did I do?

sudo apt-get install alsa-base alsa-utils
sudo modprobe snd_bcm2835
sudo amixer cset numid=3 1

System answer: "Amixer: Control default open error. No such file or directory".

I tried to get that working several times also enabling the "devel package".
No success until now.

Is this behavioure a bug or only due to the fact that I try to adapt a solution that is working on RP1 but not on RP3.


Thank you in advance

I suppose you do not use the latest release, because latest release loads snd_bcm2835 automatically if dtparam=audio=on is set in /boot/config.txt (this will be done per default on latest release)

I get on my RPi3:

Terminal

$ sudo aplay -l
**** Liste der Hardware-Geräte (PLAYBACK) ****
Karte 0: ALSA [bcm2835 ALSA], Gerät 0: bcm2835 ALSA [bcm2835 ALSA]
Sub-Geräte: 8/8
Sub-Gerät #0: subdevice #0
Sub-Gerät #1: subdevice #1
Sub-Gerät #2: subdevice #2
Sub-Gerät #3: subdevice #3
Sub-Gerät #4: subdevice #4
Sub-Gerät #5: subdevice #5
Sub-Gerät #6: subdevice #6
Sub-Gerät #7: subdevice #7
Karte 0: ALSA [bcm2835 ALSA], Gerät 1: bcm2835 ALSA [bcm2835 IEC958/HDMI]
Sub-Geräte: 1/1

and
Terminal

$ sudo amixer cset numid=3 1
numid=3,iface=MIXER,name='PCM Playback Route'
; type=INTEGER,access=rw------,values=1,min=0,max=2,step=0
: values=1
