[How to do instruction] 128x64 OLED with Song Status and Spectrum Display on Raspberry Pi

[Tim Curtis]

I haven't tested but give this a try

Code:

/var/www/snd-config.php
//$_alsa_loopback_disable = $_SESSION['camilladsp'] != 'off' ? 'disabled' : '';
$_alsa_loopback_disable = '';

/etc/alsa/conf.d/_sndaloop.conf
slaves {
//a { channels 2 pcm "hw:3,0" }
a { channels 2 pcm "camilladsp" }
b { channels 2 pcm "hw:Loopback,0" }
