Oops, I made a mistake, I only tested the inputs, not the outputs. Regards, Ralf [1] ------- Forwarded message ------- From: "Ralf Mardorf" To: "Jack devel" Subject: [Jack-Devel] Jack1 on FreeBSD Date: Fri, 25 Jan 2013 23:20:20 +0100 Hi :) I'm testing audio on FreeBSD. It can't compare to Linux, but it's anyway interesting. The card is a RME HDSPe AIO on FreeBSD used without TotalMix and without ALSA. The analog IOs are ok, but I get distortion and click noise or gaps when I use ADAT. When the source is zynaddsubfx with nperiods there aren't gaps, but there's distortion and there are clicks. It's only working in duplex mode and I can't drop the word length setting. I already switched nperiods from 2 to 3. It might be, that the driver is buggy, but perhaps I need unusual settings to use ADAT on FreeBSD. Does somebody know some (secret ;) settings I should test? jackd -r -doss -r48000 -p1024 -n3 -w16 -C/dev/dsp4.0 -P/dev/dsp4.0 is one of the settings I tested. I still didn't check if there are IRQ issues, which is very likely and if I can unbind devices on FreeBSD. jackd -r -doss -r48000 -p1024 -n3 -w16 -C/dev/dsp4.0 -P/dev/dsp4.0 jackd 0.121.3 Except for being limited to only 2 IOs with ADAT and not the very best latency, the card on Linux can be used for serious production. It's likely that it's a driver issue, but perhaps there is some magic that can be done by jack, resp. OSS settings to get it working on FreeBSD too. Any hints are welcome.
