Yaobing: Nice answer!, thanks a lot!!!
OK: Got it working, BUT....
1. I hadn't reinstalled properly (oops) the wv plugin. Earlier builds of MC on update didn't uninstall the plugs, 161 update did and I didn't realize that.
. Used Plugin manager and installed it again.
2. Now the wv files play both ways: with plugin and with direct show filters (I use Shark007's Vista codec pack, both x32 and x64)
BUT: On play (
and this happens with both methods, plugin and directshow) the play starts with a really loud and harsh sound, sort of gunshot. Volume of the wv files is much higher (at least 50%) than other formats (flac, wav, wma, mp3). If I stop playing and start another wv, the "gunshot" starts again at each start of a wv file. When stopping the playing of a wv and selecting other format, the "gunshot" is also present and the other format WON'T play. I have to press STOP and then play again of the other format, then it plays normally.
It looks like that when the wv decoding kicks in it generates the noise and volume changes. On stopping playback it looks like it got "stuck" somehow.
This did NOT happen in build 152.
With other players using direct show this does not happen, all files (including wv) play OK, same sound level, no "gunshots".
Any ideas?
