To people who already downloaded 0.9x-6 : please throw away that version and don't use it for anything.
After waking up this morning and cruising my car to the other job, I suddenly knew why for a first time I had the stalling of sound; From the release notes of 0.9x-6 :
Issue left : When the services are told to stop, and at starting an album which has to be e.g. FLAC converted, sound may stall briefly a few times during that period. This is to be solved of course.
Note : this has been reported, and was a perceived cause due to the early OSD starting, but it just happened here once while the OSD now really starts only after such a conversion. YMMV ?
... there is all kinds of debug code in there, working right in the middle of the playback engine, and I forgot to remove it.
So the sound will be baaaad, and it's my guess some systems won't even be able to produce sound without glitches.
Right now I can't get to the system, but I will solve it as soon as I am back.
Sorry for the inconvenience and apologies to those who might have been looking and looking why their system behaved so badly.
