That's not correct - module-combine-sink does handle removing hardware (I just verified this myself - works fine). This sounds like a sound card driver bug that is somehow triggered by module-combine-sink. When I asked to check with gdb where pulseaudio is hanging, I meant getting a backtrace, which would then probably show that it's some alsa call that is hung. (Sorry for not being more responsive, I don't have much time for engaging with bug reports.)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
