Now I'm getting a very large number of messages reading: **** alsa_pcm: xrun of at least 1227061150613.504 msecs I'm running F9 on an x86_64 system with all updates installed. Pulseaudio is not running. Jackd is started via qjackctl. No past problems with audio beyond the usual conflicts between pulseaudio and firefox. Questions: (1) What exactly does this message mean? An "xrun" is a buffer under- or over-run -- but what does the time interval represent? (2) Whatever the time interval means, it looks rather large. 1227061150613.504 msec is many days (or maybe years if msec means millisec and not microsec) This looks like a misconfiguration of some kind or a missing component. Any idea what it might be? </blockquote><div> The solution depends on your card (I have an Intel onboard card).
