| Hardware | jackd command line | Comments |
|---|---|---|
| Creative SoundBlaster Live 5.1 | jackd -R -dalsa -dhw:0 -r48000 -p256 | Buffer sizes lower than 128 frames do not work. |
| Emagic a26 (usb) | jackd -R -dalsa -dhw:0 -r44100 -p256 -n3 | both -r44100 and -r48000 works. will generate correct input and output number (2 ins, 6 outs). -r96000 works and will generate 2 ins, 2 outs. (Audio interface's limitation). |
| HDA Intel ALC883 Analog | jackd -R -dalsa -dhw:0,0 -r44100 -p256 -n3 | -r48000 and -r96000 works. |
| Terratec Aureon 5.1 PCI | jackd -R -dalsa -dhw:0,2 -r48000 -p256 -n2 -P -S | These settings are for S/PDIF out. 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. Other rates 44100 etc.. also work |
