Invisible XRUNS with FA-101 firewire interface

Hello, Ive been working with this problem for the last couple weeks. I have an edirol fa-101 firewire box that works perfectly in linux. Ive previously had it running with Gentoo, but now I am trying 64 Studio. No matter what latency settings I configure Jack with I always get clicks in the playback of audio that I am trying to record. It also records some clicks also. Ive tried a number a things such as upgrading freebob drivers (not to the latest in svn), upgrading lib1394, making sure acpi is turned on, and nothing works. Jack is not reporting any xruns, but I can hear it click. Ive never had this problem on my Gentoo setup. Thanks for any help.

Installed Jackdmp from backports

and, I still have my midi ports active. I suppose it is not jack, but the underlying drivers that needs work.

jackdmp + midi

Jackdmp is now called Jack2 amongst jack developers. They are putting a lot of effort into importing all the jack1 functionality into it, because when completed it will replace jack1 completely. It will even run on 1 core processors, as 1 core processor machines are multi core machines with 1 core... When Jack2 is stable enough it will be included in 64 Studio... Just wait a little

In my case, with a brand new

In my case, with a brand new FA-66, I had to compile and install jackdmp 0.70. The only problem: I have no midi appearing in Qjacktcl so I had to use my old Midisport 2x2 to get midi... So far, the performance of FA-66 combined with the 1.03 freebob drivers and jackdmp is absolutely brilliant. I could get down as low as 2 buffers of 64 samples without any Xruns nor clicks and pops. Now, if I could only find a way to use the midi ports on my FA-66 under jackdmp, it would look like paradise... Concerning the mixer, there's none in freebob I think for the Edirol devices.

I'm exactly in the same

I'm exactly in the same case for midi. So if you'd get some answers....

Onboard clipping

Yes, this is the reason why I went out and bought the RME Hammerfall, and an ADAT adapter for my digi mixer. My Audigy also used to do this sometimes. The Audio is fine inside the OS, but the moment it gets out it is mangled in the hardware... With the ADAT route it stays digital all the way until it is converted D/A in the master channel output. Do try the mixer (Double click on the little speaker in the panel next to the clock)

If Jackd is not reporting xruns the problem could be in the mixer channel values. Try decreasing them in the mixer or on the interface if possible. Your clicks may be a sign of signal clipping due to too high channel values somewhere along the audio route - very annoying, I agree.
