Hi,

I have installed a Zero soundcard on a RPI3 ... whenever I run arecord -l I get "no soundcards found..."

dmesg | grep "audio"

[ 4.204782] audioinjector-stereo soc ASoC: CODEC DAI wm8731-hifi not registered - will retry
[ 4.204793] audioinjector-stereo soc snd_soc_register_card failed (-517)
[ 4.876860] audioinjector-stereo soc wm8731-hifi <-> 3f203000.i2s mapping ok

any help?

OK - your card is initialised correctly.

Can you please output the results of the following :

Code: Select all

aplay -l

and

Code: Select all

arecord -l

and does alsamixer show anything ?

[customcables067]

Results:


aplay: device_list:268: no soundcards found...
arecord: device_list:268: no soundcards found...

What is alsamixer? (I only access via SSH, I don't have a monitor attached).

when you run dmesg grep "audio" are you sure you see this line :

Code: Select all

wm8731-hifi <-> 3f203000.i2s mapping ok

That line indicates sound card registration, however aplay suggests you don't have any sound cards registered !

Here are my results :

Everything is identical in config except my arecord -l and aplay -l outputs show "no soundcards found"

[flatmax]

Very strange, your card is set up by the system.
I assume alsamixer says no card as well ?
do you have anything in ~/.asoundrc or /etc/asound.conf ?

thanks

I'm in SSH via Putty so I don't have access to alsamixer.

asound.conf is empty.

Not sure what ~/.asoundrc is.
