Unable to install to SD-CARD

[agent_kith]

That installed. Unfortunately the MacMini does not see the SD card after reboot. So there is no way to test it. 

Hmm.. When you see the boot menu, hit the 'E' button, and then take a picture.

I guess I can think about installing on the SSD.   Is there reason to believe the Sound Quality is better with the new release, and if so, what has changed to provide that? 

Here's a intro describing the new changes. The Snakeoil OS WebApp is now re-written in C++ and multi-threaded. When using the WebApp, the browser is now doing a lot more heavy lifting compared to before. 

All the music players have been recompiled with tools from Ubuntu 16.04 . The ALSA library Snakeoil is using is also a newer version. Overall I do think the SQ is better compared to the 0.1.x, some have privately reported the same as well. But I'm sure you know "better" is a subjective thing. The only way is to install it and assess the SQ yourself.
