The latest update patch from pulseaudio breaks HDMI sound function on a X201 Lenovo with docking station
Last modified: 2015-04-22 11:59:09 UTC
After installing patch RU-2015:071-1 did break completely the sound function on the following setup: Lenovo X201 notebook Lenovo Ultrabase dockingstation HDMI sound over a Medion MD20666 Everything worked well with HDMI sound selected when on dockingstation and normal analog when on notebook only. Now after the update the HDMI as channel is not available. Sound is, if it is possible to configure the sound card (possible one time in two) only over the speakers of the machine. Channels are indicated correctly when in kmix, priority is set correctly but not respected. When selecting to set up for all channels the audio configuration this is not set and not respected and one has to do by hand. But then it has no effect on the problem. The different soundcard resources are shown only with no application running. When running e.g. kaffeine, reproduces over the notebookspeakers, and as channels in Kmix there is only "sound server pulseaudio". But that soundserver does not seem to respect the settings done in channels before. Shortly it is a mess. Up to the update everything went quite smooth.
The fix will be released soon. *** This bug has been marked as a duplicate of bug 928035 ***
