I thought I could replicate this earlier today, as pulse CPU did go very high for a while with network sinks, and it fell away when I unticked the boxes in paprefs. But I can't replicate now I try to sit down and look at it :s That said, one end of my loop is 0.9.10 so not sure how valid a test this is. I'll try and upgrade the other side shortly. > This is the best thing about Linux when it works. I'm starting to > think I'm going mad; (I can't be the only one using the network > stuff, surely? Why has nobody else reported this?) To be fair there are probably not a huge number of people using 0.9.14. Quite a lot of distros stuck with 0.9.10 and are only shipping 0.9.14/15 in the next round of releases which are coming up now. And of those using the newer versions, only a small subset will use networking. So it's not surprising that you're the only one reporting this... you're a pioneer! Be proud! :p To debug further, it would be good to run pulseaudio manually on each machine via -vvv args and see if anything is printed when the CPU goes skyward.
