A comment line below in the code for Audio Config shows Camilla is only enabled for certain Pi models and the zero 2 is not included in the list.
Code:// Pi-2B rev 1.2, Allo USBridge SIG, Pi-3B/B+/A+, Pi-4B
@bitlab, should zero-2 be added to list for upcoming moOde 8 series?

@Tim Curtis, @bitlab
Adding my CM4 was straight forward but the Zero 2 W will be a bit trickier.
In /var/www/snd-config.php we find this snippet
Code:
$model = substr($_SESSION['hdwrrev'], 3, 1);
$cmmodel = substr($_SESSION['hdwrrev'], 3, 3); // Generic Pi-CM3+, Pi-CM4 for future use
$name = $_SESSION['hdwrrev'];
// Pi-2B rev 1.2, Allo USBridge SIG, Pi-3B/B+/A+, Pi-4B
if ($name == 'Pi-2B 1.2 1GB' || $model == '3' || $model == '4' || $name == 'Allo USBridge SIG [CM3+ Lite 1GB v1.0]') {
$_camilladsp_set_disabled = ($_SESSION['invert_polarity'] != '0' || $_SESSION['crossfeed'] != 'Off' || $_SESSION['eqfa12p'] != 'Off' || $_SESSION['alsaeq
ual'] != 'Off') ? 'disabled' : '';
}
else {
$_camilladsp_set_disabled = 'disabled';
}Here's what debugging reveals for three boards of mine
Code:
Raspberry Pi 3B+
$model = 3
$cmmodel = 3B+
$name = Pi-3B+ 1.3 1GB
Compute Module 4 4GB
$model = C
$cmmodel = CM4
$name = Pi-CM4 1.0 4GB
Zero 2 W
$model = Z
$cmmodel = Zer
$name = Pi-Zero 2 W 1.0 512MBAs you can see, adding the CM4 was just a matter of introducing an additional if clause
|| $cmmodel = "CM4"
OTOH, the existing substring variables aren't much use with the Zero 2 W. I might hack something tonight just to convince myself it is a viable platform but I can't imagine it isn't. It's performance is rather similar to the Pi 3A+

Might have to do something like below...
Code:
(strpos($name, 'Pi-Zero 2') !== false)RE: Pi Zero 2 W - TheOldPresbyope - 01-07-2022

Yup. Now can enable camilladsp on my Zero 2 W as well as my CM4.
No time to benchmark comprehensively but just choosing the conv_ae_oratory1990__hd800s configuration, setting the Pi HDMI or Pi Audio jack as output device, and looking at the output from the top command while playing an Internet radio station I see the camilladsp process consuming;
6.6% CPU on RPi4B
6.6% CPU on CM4
8.6% CPU on RPi3B+
12.3% CPU on Zero 2 W
(where all the percentages jump around in roughly a 1% range).
The Zero 2 W seems up to the challenge.

My Zero 2 W arrived today. Yay ! :-) $25 NZ (16.57 US)+ shipping($6.50 NZ) and still there are traders locally offering for $89.00 NZ ($59.01 US)
+ ($10.00 NZ) shipping
