ah, I forgot about audio(4) buffers being limited to 65536 bytes. 12 channels * 4 bytes per sample = 48 bytes per frame. jackd uses 2 buffers of 1024 frames each by default, so you need 2048 frames of buffer space, which is 98304 bytes, which won't work. instead, tell jackd to use 512 frame buffers (2 * 512 * 48 = 49152): $ jackd -d sun -o 10 -i 12 -w 32 -p 512 there is still an inefficiency with duplex mode in the current port though. I'm waiting for upstream to make a decision about another patch before I update the port. > Thx for your help . > > -- > Jean-michel Bessot <[EMAIL PROTECTED]> > -- [EMAIL PROTECTED] SDF Public Access UNIX System - http://sdf.lonestar.org
