I have tried that and yes it Works. But I still look forward to the new beta. I can't use Rune without WIFI support. I found some code that could ad WIFI, but I can't use it because Rune forget the settings when rebooting.
The IQaudIO Pi-DAC exposes gpio 22/23/24/25/27, 3v3 and also i2c allowing additional small load devices to be connected without hacking or soldering things.
