Raspbery Pi 3 no sound card

Postby m4thu » Sun Oct 29, 2017 7:48 am

Hey,

I have no sound card except vc4-hdmi on my system. And that is kinda bad, as I would like to use my raspberry as a pulseaudio server. Anybody has an idea?

$this->bbcode_second_pass_code('', 'root@alarm /home/alarm # cat /proc/asound/cards
0 [vc4hdmi ]: vc4-hdmi - vc4-hdmi
vc4-hdmi
')

$this->bbcode_second_pass_code('', 'root@alarm /home/alarm # cat /boot/config.txt
dtparam=audio=on
')

$this->bbcode_second_pass_code('', 'root@alarm /home/alarm # lsmod

I wouldn't recommend it. Raspberry Pi aren't great at audio. Their audio output only has 10bit precision.

Hello.

I'm not that sure, but maybe you have to enable the i2c interfaces in config.txt. For reference, my config.txt

$this->bbcode_second_pass_code('', 'device_tree_param=spi=on
gpu_mem=128
disable_overscan=1
dtparam=audio=on
dtparam=i2c1=on
dtparam=i2c_arm=on')

and the alsa-cards and loaded kernel-modules.

$this->bbcode_second_pass_code('', '$ cat /proc/asound/cards
0 [ALSA ]: bcm2835 - bcm2835 ALSA
bcm2835 ALSA
