For some reason it won't work at all with S/PDIF duplex. You can use smaller buffer sizes, but below 32 samples (1.33 ms) xruns start to appear on my machine. | | RME Digi96/8 PCI | ''jackd -R -dalsa -dhw:0 -r44100 -p256 -n2'' | -r44100 works, -r48000 not yet tried. | | Phonic Helixboard 12 Firewire | ''jackd -R -dfreebob -r96000 -p256 -n3 -D'' | Works perfectly, have not tried lower than 256 | | Presonus Firepod Firewire | ''jackd -R -dfreebob -r96000 -p128 -n3'' | Works great.
