The current default allows stereo capture and playback at any sample rate, albeit at the expense of multichannel, low latency capabilities. This is the best default. The other problem with the FX capture device is that currently the only way to select the channels to record is to manually edit asound.state and then do alsactl restore. To put this in the mixer, we would need to add 'EFX Voices Mask', consisting of 64 boolean values, and the number of these which are unmuted at any given time must be a power of two. Not sure if this is possible with the current mixer API, it certainly would not be pretty. Anyway, this issue is moot, because it turns out that JACK does support full-duplex mode using different devices for capture and playback. The documentation and help text was incorrect. This will be fixed in the next JACK release. The next release of qjackctl will also be updated to reflect this development, as qjackctl currently disables the selection of input and output devices if full duplex mode is selected.
