Then apparently the other process stopped using the card, and pulseaudio started to probe it, but during the probing again the third HDMI/DP device was busy again. There were three HDMI/DP devices that were not busy, but they were not connected to anything either. (Even if you have just one physical HDMI/DP connector, it's normal to have several devices appearing in alsa, they are just not connected anywhere.) Try running "lsof /dev/snd/pcm*" when you notice a problem. That command will list all processes that have alsa PCM devices open. If some other program is using the sound card directly, that will cause problems with pulseaudio.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
