I usually use the Audio 8 for TSP sessions on my mac laptop. Now i am attempting to use the A8 with my mac desktop machine so i can use it with Ableton. The A8 icon/driver is visible in System Preferences. The A8 is also selected in System Preferences - Sound. But is says on both Input & Output tabs that "The Selected Device Has No Input/Output Controls". In utilities - Audio Midi Setup - Audio Devices, i have selected the A8 for everything. On the fist attempt, in the Audio Devices section Stream 1 (outputs 1-2) were set as default (and also in the configure speakers tab!), these connections were too made on the back of the A8 unit. There was then very, very loud audio coming from my monitors but nothing through the headphone output and there also appeared to be no Rotarys etc on the A8 unit to reduce the main output control to my monitors. After spending further time reading he manual, it advised to select Stream 4 (outputs 7-8). I made these connections on the back of the A8 unit first and then selected Stream 4 in 'Utilities - Audio Midi Setup - Audio Devices'. But after also selecting Stream 4 in the Configure Speakers Tab, it would always automatically resumed to Stream 1!). After this configuration. there was no sound coming through my system at all! Am i missing something? Can the A8 not be operated the same as dedicated Audio Interfaces such as my t.c. electronic konnekt 8?
