FAQ

Q1: Why My DAC card shows ALSA fault?

A:

1. This is a compatibility issue of VOLUMIO system. and we fund some related issues about ALSA on VOLUMIO.ORG. Here also is anything we search on google: https://cse.google.com/cse?cx=partner-pub-0839303782430158:6119498809&q=ALSA%20&oq=ALSA%20&gs_l=partner-generic.12...1677.1677.0.2228.0.0.0.0.0.0.0.0..0.0.gsnos%2Cn%3D13...0.46j2116j2...1.34.partner-generic..0.0.0.

2. We recommend not to open the alsa option, otherwise it will result in the loss of the driver (configuration) file. in fact, this audio board supports hardware to adjust the volume. If the system fixes this problem, we will post a message on the wiki, please pay attention to our wiki.

I have the same problem that I can't find Aoide DAC II in Volumio 3. When I try with Volumio 2 images from the list I always get the message 'This board requires newer software'. I'm also using a RPi4B.
