Update: I have no idea why MPlayer now work as expected (with floatle outputs) when starting Jack with my 16 bit USB module: jackd -r -d alsa -d hw:2 -P -o 8 -z shaped Although it would have been nice to use zita-j2a for resampling... What was the problem then? I hope it's not intermittent, and that it's not only related to the device between my ears. :) Then I tried to add the 2 channels internal sound device: zita-j2a -v -d hw:1 (no sound) zita-j2a -v -d hw:1 -L (no sound) Salut -- Marc I wrote: > Bonjour Fons. > > Fons Adriaensen <fons@xxxxxxxxxxxxxx> a écrit : > > First of all, what are you trying to achieve ? > > I don't want to use "depth down-sampled" channels with ambdec. > > > Zita-j2a is normally used to add a playback alsa device to Jack. > > For example, if you use Jack with the internal soundcard, then > > starting zita-j2a with the USB card will add the outputs of the > > USB card to jack, you can then play via both cards at the same time. > > As I wrote, zita-j2a stays silent when using it as you explained. > > > As said, Jack is *always* using floating point. > > Excellent! > > But when running jackd with my 16bit USB module, Mplayer is converting > its output to 16bit.
