#271: XRUNs on FA-66: Instantanous samplerate more than 1% off nominal -----------------------------+---------------------------------------------- Reporter: joh | Owner: Type: bug | Status: new Priority: major | Milestone: Component: devices/bebob | Version: FFADO 2.0-rc2 (1.999.42) Resolution: | Keywords: Device_name: | -----------------------------+---------------------------------------------- Comment (by joh): I disconnected all USB devices that were doing interrupts on IRQ18. A 'watch -n 0.5 cat /proc/interrupts' revealed that there were no interrupts going on when I started jackd. That's enough to indicate that the ti- firewire port has exclusive use of IRQ18, right? Anyway, this did not seem to help any - lots of XRUNs still when playing a movie with mplayer -vo xv. It seems the fglrx driver locks some resource for too long and this causes the XRUNs on the firewire bus. Might be that the PCI bus is locked for too long? Not sure what else to try now but wait for updates to fglrx / open source driver. -- Ticket URL: <http://subversion.ffado.org/ticket/271#comment:6> FFADO <http://subversion.ffado.org/index.fcgi> Free Firewire Audio Drivers |
