AJ Thanks for the reply.
I haven't looked at the Lightning for some time, but as my TSR2 (still in development) suddenly started producing funny glitches in the engine sound I went back to your Lightning, from which I had stolen this particular piece of code (many GPL thanks). Subsequently I have found the same problem, to various degrees, in other aircraft, including Sea Vixen. It hard to describe, but is a kind of background twittering. I hear the same effect in Linux and Windows. Off topic, whilst looking for further examples I found many aircraft that do not work. Concorde just crashes Flightgear, and several aircraft have translucent HUD and/or cockpits. This is with Rembrandt enabled. As Eric says stereo has been discontinued for some time, and he is the one to explain the benefits of this change. I think that there is a stereo effect still, as rotating the viewpoint causes significant volume changes, which must be based upon sound source position. This particular effect seems to me rather unrealistic, as when I turn my head in real life the noise of my surroundings does not change to such a great degree.

IMO it's a huge shame that stereo sounds are not supported any more, as the aural experience now just isn't as immersive (not to negate the real improvements that _were_ made of course). I'm not sure I understand why stereo can't be supported - couldn't the relative volumes / pitches of the two channels of the sound clip be adjusted fairly easily to provide positional cues? > The second problem is that the HSI spins continuously until the “Push > Source” button at the bottom of the instrument is pressed.

Thanks for reporting these, a major shortage of "spare" time means I'm not able to be involved as I once was but would like to keep the stuff I have done working at least!
