Thank you for the feedback. I can think of no obvious reason forwhy a 30ms buffer size would create the difficulty with the 22050Hz MP3 track. But I haven't actually tried that combination, and may do so in due course. As far as I could see, the 'UE radio' playback system differs in no material respect to the 'Baby', which I have used for testing. I'm not aware of any issues with using 40ms, or any downsides to doing that. But I haven't used that setting extensively, so I can only suggest that you try it out. It occurred to me that it might lead to synchronization deficiencies between players, but I'm not sure. Since my last post, in July, I have carried out some further testing and trials. I am now of the view that the problem probably lies somewhere within the kernel audio drivers, and not within Squeezeplay's Crossover component, as I had first surmised. The immediate cause of the effect is somewhat mundane, and I don't know why I hadn't noticed it before. Basically the 'Tweeter/Left' and 'Woofer/Right' channels are simply being switched around. So the tweeter is fed with sound intended for the woofer, and vice versa. The effect can be easily discerned when listening to a heavily panned stereo track through headphones. (The Crossover is inactive in that circumstance). I have tried installing some later alsa libraries in the hope that there may be an issue therein. But to no good effect. There was no obvious reason to think that there would be, but it was worth trying. I can see that a (lightly) patched version of jive_alsa would also help mitigate matters further when a stream is just being started up. It has been on those occasions that I am conscious of experiencing the issue. But it is too rare an occurrence to be sure.
