I'd appreciate any helpful suggestions with an echo problem. I'm using a Focusrite Scarlett 2i2 with mic plugged in front jack and rear panel line out driving external equipment. Audiomulch is set for 96kHz sample rate, ASIO driver type and Focusrite USB driver for input and output. In Windows sound, Scarlett record/playback is set for 2-channel, 16-bit, 96KHz. I'm hearing a slight echo on the Scarlett line output audio. I tried muting the Playback level (Audiomulch knowledgebase suggestion for the echo problem) with no change.
