I think what I would do is remove or comment out the
<console>  0600 <sound>      0600 root
line from /etc/security/console.perms.d/50-default.perms. I would
then copy the device list from the audio devices section of
/etc/udev/rules.d/50-udev.rules and create my own file as something
like 52-sound.rules with lines like:

KERNEL=="audio*", GROUP="audio"

or what ever group you want to be able to access the audio devices.

By removing the <sound> line from console.perms control, the
permissions set by udev will prevail. By adding another rule file
for udev, instead of editing 50-udev.rules, your changes should
survive a udev update. You may still run into problems with a
console.perms update...
