Package: pyhoca-gui Version: 0.5.0.0-preview
I'd clone x2goclient bug #363 if I could. It is the same underlying issue that also affected x2goclient.
I am about to commit the fix. Instead of providing separate PulseAudio 0.9.6 builds like I did for X2Go Client 4.0.1.x, I will upgrade PyHoca-GUI's bundled PulseAudio from 1.1 to 5.0-rev18. (Same as X2Go Client 4.0.2.0 ships.) -rev18 (the version suffix from the OpenSUSE OBS) includes the upstream patch for this issue.
