This is a known issue and it is caused by MP itself.1. If I am listening to one song and press skip on the remote to go the next song, there is some stutter in the music and first after that the current song fades out and the next one fades in. Can I get rid of the stutter in some way by changing the configuration?
However, it happens to be fixed today, so the stutter will be gone with the next SVN build or MP 0.1.0.1.
It's not any intelligent encoding, it just puts left on front-left and rear-left and right on front-right and rear-right.2. I noticed in the configuration that it is possible to upmix stereo to "QaudraphonicPhonic". Is this some kind of Dolby ProLogic II-like matrix encoding with phase inverted surround sound? If it is, what is needed to use this mode? Will it work on analog output? SPDIF? HDMI? How does PureAudio know what speakers are surround speakers?
Works on any audiodevice that has 4 channels or more, so not on spdif (spdif only has 2 channels)
