Guilty as charged. On GNU/Linux systems, the Debian package builds jackd with the following flags: DEB_CONFIGURE_EXTRA_FLAGS := --enable-resize \ --enable-timestamps --disable-iec61883 --with-oldtrans \ --disable-ensure-mlock # --enable-posix-shm DEB_CONFIGURE_EXTRA_FLAGS += --enable-stripped-jackd DEB_CONFIGURE_EXTRA_FLAGS += --enable-capabilities --with-default-tmpdir=/dev/shm > > It looks like the package was built to use capabilities.

I certainly hope not. I thought that was a spurious error message to be disregarded, since jackd definitely *is* running with RT priorities, at least on my machine, it reports: FreeBoB MSG: Streaming thread running with Realtime scheduling, priority 74 FreeBoB MSG: Registering capture port dev1c_MicIn1 left And ps says... PID CLS RTPRIO NI PRI %CPU STAT COMMAND 3423 TS - 0 20 0.0 SLl jackd 3423 TS - 0 24 0.0 SLl jackd 3423 TS - 0 24 0.0 SLl jackd 3423 TS - 0 19 0.0 SLl jackd 3423 FF 80 - 120 0.0 SLl jackd 3423 FF 70 - 110 1.5 SLl jackd 3423 FF 73 - 113 5.6 SLl jackd 3423 FF 73 - 113 5.0 SLl jackd 3423 FF 84 - 124 0.0 SLl jackd 3423 FF 74 - 114 5.4 SLl jackd Although, I just noticed now that some of those jackd threads aren't running with any RT prio at all. And, I also noticed that the little yellow "RT" in qjackctl isn't lit up either... Is that OK? Or is this a problem? I'm standing by and waiting to hear from the jackd developers before filing this with the Debian bug tracking system... And also waiting to hear back before I go out and blow $400 on a 2.4Ghz CPU.... - -ken -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFFxpAQe8HF+6xeOIcRAjpjAKD/LrSfNPi3Y6jG9hWDkBndU6x0ygCeNM3x L+iL4L6UEN2XSJIthQ+kLn0= =LHn6 -----END PGP SIGNATURE-----
