[SOLVED]Pi 2 Model B+ doesn‘t detect the soundcard

Postby revo86er » Sun Sep 18, 2016 11:12 am

Hi,
Since a couple of months the Sound of my Pi doesn‘t work after an update

root@ArchARMv7 ~# speaker-test -c 2:
$this->bbcode_second_pass_code('', 'speaker-test 1.1.2
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels

root@ArchARMv7 ~# aplay -L | grep :CARD
returns nothing

cat /etc/asound.conf
$this->bbcode_second_pass_code('', '# Use PulseAudio by default
pcm.!default {
type pulse
fallback "sysdefault"
hint {

description "Default ALSA Output (currently PulseAudio Sound Server)"
}
}

ctl.!default {
type pulse
fallback "sysdefault"
}
btw a ~/.asoundrc doesn't exist')

root@ArchARMv7 ~# cat /proc/asound/modules
returns nothing

root@ArchARMv7 ~# lsmod | grep snd
$this->bbcode_second_pass_code('', 'snd_bcm2835 22495 0

root@ArchARMv7 ~# ls -l /dev/snd
$this->bbcode_second_pass_code('', 'total 0

root@ArchARMv7 ~# inxi -Fx #system_info

root@ArchARMv7 ~# cat /proc/asound/cards
--- no soundcards ---

So, obviously my Pi doesn‘t detect the soundcard. I tried already a lot of hours to fix this but haven‘t got so far yet.

Does anyone has a clue to point me in the right direction? Cheers...

I solved it, sry for the drama guys ;)

$this->bbcode_second_pass_quote('', 'T')o correct this, assuming the device tree is enabled, add the following to '/boot/config.txt':

dtparam=audio=on

Cheers!
