[SOLVED] No audio devices on RPi5 with latests builds

[hkphantomgtr]

I've installed 1.4.1 on my rpi5 over recommended Ubuntu server but I couldn't get any audio device detected. I did update to 1.4.2 but still no audio devices. Also tried to alter config.txt in boot folder but no success. My intention is to use rpi hat dac with 2 es9038q2m dac chips of Ian canada and maybe  some USB dacs.

Would you please show us the path of your config.txt and content of that config.txt?  For the USB dac, it only shows up when it's connected to Pi 5.

FYI, currently I'm building this rpi5 music server for fun and testing (the photos may take a minute to load), with a cheap clone audio hat.  It's my first audio hat.  I thought ubuntu, Raspberry OS, and some other big name audio OS will auto detect the hat and configure accordingly and automatically.  But NONE.  All shows no audio device found.  Some audio OS got a nice webui to let me to choose from a long list.  Some got to input manually in the cli, including ubuntu and raspberry OS.  For the cli case, one got to know the exact name of the overlay (driver) in that OS.  There is a folder holding them all.  Just I forgot the path at that moment.
