Yup, adding that flag does the trick, see attached patch. Thanks for the pointer. I couldn't resist removing some duplicate code, I hope that's OK. If not, I'll prepare a patch which only adds the flag. > I actually wonder if this is the cause of the vumeters sometimes not > initialising properly at times...

Well, I was pleasantly surprised to see that pavucontrol from git master worked a lot better than the version packaged on Ubuntu (0.9.9). I'll use the newest version for a while and look out for little problems like you described. > Col Maarten -------------- next part -------------- A non-text attachment was scrubbed...
