On the Audioinjector forum, people have reported problems installing volumio.
The Audio injector stereo sound card supports up to 96 kHZ with 32 bit word sizes.
This thread discusses the installation of volumio with that sound card.
Someone has reported getting volumio to work by compiling their own kernel. However the audio injector stereo cards run out of the box with the raspbian kernel.
What is involved in getting volumio support for the audio injector stereo card ?
