We have been sourcing mini-optical jacks for our wireless audio project and noticed that the usual distributors no longer carry them. It seems the main Japanese supplier, Sharp, no longer manufactures any optical audio jacks. I don't think this is because the interface has fallen out of favor, but more to do with the economy. Currently, it appears the mini-optical audio jacks are only available directly from Chinese manufacturers, which makes prototyping 'fun.'

Does anynone know why this is the case and a good reliable source to acquire them? We received some Chinese samples (at considerable shipping expense)which were okay except the receivers don't work at all!

Thanks,
Stu
