Pardon me but I think I'll need more explanation to this.

Yet no support of full copy of music playback as on PS ('danger' and so on). Also there is support of additional music tracks for chosen (in music.txt) locations and something like dynamic playback (optional DSP-filters for Underwater and Spectral Realm). This patch fixes bugs with sound (music & voices, not sfx), including wrong behavior of music on pause (restarting) and unrefreshing it at the edge of locations. I would be happy to hear there is a fix to that but I will totally understand if there isn't, I've read some topics already about sound in this game and it seems like I'll have to get over it. With software mode it kinda helps, but it still takes a lot of time for the game to realize that I am in a different area. I tried to fiddle around the settings, textures, different video settings etc. After unpausing it begins playing the normal version of the track in that particular place I'm in, even if I'm currently in the spectral. Besides that my game seems to be missing tracks from the spectral realm which is a real bummer for me because I really loved those. except that background ambience audios won't start at the beginning of new area until I pause the game and unpause it. Most of it plays as it should, there are no sfx glitches, voices are perfectly fine, intro played without problems, it's all good. It's not gamebraking or anything but, it just bothers me a bit. I am well aware that Soul Reaver is a very old game and it's very likely to spawn some issues.
