I've not actually tried what Jamulus does in that situation (but will do) but it seems a bit strange to me. Does it have some inherent advantage? That being said: I was particularly looking for the Presonus Audiobox USB these days (since I guess Presonus cards newer than the lacklustre Firebox are supposed to have good preamps/gains) but with regard to latency, it doesn't seem like the greatest choice. -- David Kastrup _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
