--- Comment #15 from diafero@arcor.de 2012-12-13 09:33:18 CST --- The 2nd patch you mentioned has already landed in wine 1.5.19, which did not help. The first one did not change anything either.
It just came to my mind that the behavioural change might also be caused by a difference in my wine setup (well, this is a totally different machine than back then, but anyway): I am now using PulseAudio, and the winepulse driver from http://repo.or.cz/w/wine/multimedia.git (without these, sound is mostly broken, not only in Uru but also in other games).
