If you need "sham" latency value, using libffado stuff is suitable to your aim. In a point of packet streaming protocol for IEC 61883-1/6 and interrupt interval of OHCI 1394 context, ALSA bebob driver has minimum value for PCM frames in one buffer period. Currently tt's 5msec. In detail, see comment of corresponding code: http://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/tree/sound/firewire/amdtp-stream.c#n140 Jackd with firewire backend just displays value convenient to users, although it's not reasonable in a technical point. Well, about the noise you heard, I can't re-generate the issue. So we could judge it depending on environment. Do you explain more details? Which application you use? What OHCI 1394 controller you use? And so on. > My main problem already only; > > After when I turn off the soundcard and/or the laptop, I need to start > again the ffado-mixer to turning on the channels (default: every channel > muted, or inactive).

Please use ffado-dbus-server/ffado-mixer or libhinawa/hinawa-utils.
