A bit of a problem with the audio source and sink selection menus in the interface app in Win7. It looks like the menu item builder is pruning same names, and that makes it impossible to select audio sources/sinks named the same. This is quite common with gamer computers that have multiple speakers, all labeled “Speaker”. Fortunately, I could work around this by relabeling all the sound assets, but collapsing same named items is not a good thing.
Running Debian Jessie, audio problem. Ah! MY BAD! When I finished building Hifi I immediately ran it …as root user. DOAH! When I fired up interface as user I got three pulseaudio channels. When I hit “esc” to goto the lobby thingie, I got elevator music on one instance and hiss on another. Still working on it. Ric
