Hi Len. I would like to use jackd in 32bit (or is it 24bit, or float?) but output in 16bit (resampled with zita-j2a). This is to play 24bit files with the best possible quality when using multiple 16bit sound cards or USB modules. When starting jackd normally (with the alsa backend and a 16bit sound card), mplayer output is 16bit (that's not what I want). When starting jackd with the dummy backend, or the alsa backend connected to a loop device, jackd works in 32bit float and mplayer output is floatle; jackd doesn't report sync problems and mplayer just plays the file. Then I connect the floatle output of mplayer to zita-j2a, there's no sound. Even when starting jackd with the internal sound card, zita-j2a stays silent. -- Marc Len Ovens <len@xxxxxxxxxxxxx> a écrit : > On Fri, 19 Jul 2013, Marc Lavallée wrote: > > > For some reason, zita-j2a 0.2.2 is silent on my laptop.
