-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Thanks Johannes; this sounds promising. I probably don't even need the mixer but will stick to one particular routing most of the time (DAW outputs sequentially to analog outputs then digital), also I need neither zero latency monitoring nor standalone operation right now. I'm using Debian Jessie which I think is the 3.16 kernel. Probably I can just compile the linked ALSA patch even with the 3.16 kernel? Best, .h.h.
