Running Volumio 3.179 on an older Pi (2 I think? Maybe 3?) with Audioinjector Stereo sitting on top... is there a way to make it use the audioinjector stereo card? Volumio itself works but I can't get the method described here
http://forum.audioinjector.net/viewtopic.php@f=5&t=3063.html to send sound through the card...
I have editing /etc/config.text to read
volumio@volumio:~$ cat /boot/config.txt
initramfs volumio.initrd
gpu_mem=32
max_usb_current=1
#dtparam=audio=on
#audio_pwm_mode=2
dtparam=i2c_arm=on
disable_splash=1
hdmi_force_hotplug=1
force_eeprom_read=0
dtoverlay=audioinjector-wm8731-audio
include userconfig.txt
I get this after reboot:
volumio@volumio:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: audioinjectorpi [audioinjector-pi-soundcard], device 0: AudioInjector audio wm8731-hifi-0 [AudioInjector audio wm8731-hifi-0]
Subdevices: 1/1
Subdevice #0: subdevice #0
The recommended mixer command doesn't seem to work:
volumio@volumio:~$ amixer sset 'Output Mixer HiFi' toggle
amixer: Unable to find simple control 'Output Mixer HiFi',0
I get 'audioinjector-pi-soundcard' as my only available output device on the volumio web interface
Prior to making these changes, I get the expected audio output from the Pi's built in headphone jack.
After making these changes, I get no audio output from headphone jack, or output jacks on Audioinjector card, while volumio web interface is showing a song playing at max volume.
Any ideas?
