It appears the default of speex-float-1 is chosen by upstream (?... although commented out): https://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/daemon/daemon.conf.in

Please log a bug directly with them and let's see what they say: https://bugs.freedesktop.org/enter_bug.cgi?product=PulseAudio ** Changed in: pulseaudio (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1741045 Title: Change the default resample-method to speex-float-10 in daemon.conf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1741045/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
