I have been messing around with the phat dac for a little while trying to get audio out. I have no network connection (yet) on my Pi zero so I am using the manual config process with Jessie. When I run the speaker-test I get audio out of the phat dac which is great but when I try any other application it doesn’t work. For example omxplayer -o both [filename] will output to hdmi fine but not to the phat dac. So the device pops in lsmod just fine, so it must be loading. The only other issue is that when I run alsamixer I get an error “this sound device does not have any controls”.
I have a USB wifi on the way to try the script but it would be great to get some idea of what is (not) going on with my install.
