I have a(one of a number of)Ubuntu Karmic systems here running pulseaudio 0.9.19. On this particular system, PA wants to eat as much CPU as is available. It will use up near 100% on this system when it's otherwise idle. This particular machine is the only one of several, as I say, with this problem and they are all up-to-date, so I wonder if this is particular to the sound hardware in this machine. It has in it: 04:01.0 Audio device: VIA Technologies, Inc. VT1708/A [Azalia HDAC] (VIA High Definition Audio Controller) (rev 10) 05:05.0 Multimedia audio controller: Ensoniq ES1371 [AudioPCI-97] (rev 07) What other information can I gather to help diagnose this problem?
