Comment 5 for bug 1214079

I assume headset work as expected without Mixxx for example with mpv, vlc or firefox? You can test with VLC because it uses also ALSA-PulseAudio bridge if you choose ALSA from audio settings. Multiple Bluetooth devices seems to have pops and clicks because of their very high end demands or not supporting A2DP or a52 correctly. Does 'dmesg' say anything?

So if you are advanced and can compile it I can help you through using it.

If you feel lucky you can test binary package which have this patch applied from:
http://download.opensuse.org/repositories/home:/illuusio:/portaudio/

Small disclaimer it will override your current portaudio so if isn't working then nothing that uses portaudio ain't working but it should solve most PulseAudio problems.
