Wi-fi card disabled on RPI3 - audio injector not recognized.

[abonam]

Hello,
I ran into the two following issues after installing the AudioInjector:

1) I downloaded got the latest Raspbian Jessie distribution, followed the manual setup to install audioInjector card (sudo rpi-update, disabled PWM audio, added the dtoverlay=audioinjector-wm8731-audio line to the config.txt) then rebooted the system.
When I reboot, the wi-fi card is disabled, I was wondering if this is an issue with my configuration. Wi-fi access is needed by my project.

2) I was not able to see the audio injector at all.
aplay-l returned error, I am attaching the output of the command dmesg.

Thank you in advance for your help!

I'm failing to do something correctly too. I installed and ran your audioInjector-setup, and ran the test.sh. Booting doesn't seem to see/register my card, or so it seems at first, but do get an "OK? out of it

I'm no newb to linux, but I'm definitely green with all this audio stuff.

Hello,


managed to get the card registered.
All I had to do is NOT to do rpi-update...does it make any sense?

Thanks!

Hi there,

Not sure why you had trouble, this line indicates that the sound card was found and probed :
May 16 17:30:45 raspberrypi kernel: [ 4.118665] audioinjector-stereo soc wm8731-hifi <-> 3f203000.i2s mapping ok

The probing process does late probing which is why it is confusing to read the dmesg log.

Regarding rpi-update - should be no porblems running that and getting the card working !

thanks
Matt
