But when running jackd with my 16bit USB module, Mplayer is converting its output to 16bit. When running Jack with a 24bit sound card or the aloop device, Mplayer's output is floatle (as expected), even when forcing Jack to run in 16bit with the "--short" option. Another problem: when starting Jack with a 2 channels sound card, Mplayer can't output more than 2 channels. So I suppose that Mplayer is misbehaving. > It will convert the playback channels to whatever the sound card can > handle. So far, no sound is coming out of zita-j2a. Here's how I started it: zita-j2a -v -d hw:2 -c 8 playback : nchan : 8 fsamp : 48000 fsize : 256 nfrag : 2 format : S16_LE capture : not enabled Starting synchronisation.
