Bug: WMP does not select Left / Right channels correctly

[Guest Slohr]

[Edited by Site Admin, thanks for the submission slohr!]

SYMPTOM:

Windows Media Player randomly selects which sound channel to use as left/right channel. Try starting a song, with an easily recognisable left-right sound pattern, over and over, and you will find that there’s a 50/50 chance that it plays right/left rather then left/right.

RESOLUTION:

noticed that today

was walking home though so couldnt really be arsed to test it properly hehe

I was making a 2.5-3.5mm converter today and when I when to check to see if I had the channels correct, I had exactly the same problem, although it seems to not just be WiMP - Sound Manager does it too. At least I don't have to worry about getting the channels correct :lol:.

Is this a hardware problem or just a software bug? I have attached a test mp3 if anyone wants to test their stereo.

In fact this is a problem with the earphone adapter, not with WMP.

Some earphone adapters will invert channels when inserted completely, and will give you the right channels when inserted half-way. Yes, that's because Smartphones (at least the ones we tested) use a jack wiring that are not compatible with regular stereo earphones using standard adapters.

While I agree that it is not WiMP that is at fault, is still a problem with the Smartphone itself, not any adapter, as the problem occurcs with the supplied headphones aswell.

Do you confirm the observation that we made, i.e. that this is a problem with the plug ? (i.e. the channel will invert or not when you wiggle with the adapter)

No, I don't - even with the phone on the table and the plug not being touched, it still seems to randomly select which channel to use.

Is there no solution to this problem then cos it's doing my head in. It might seem a bit anal but I wan't to hear my music as it's intended to be not with the channels randomly swapped the other way around.

This happens with any media player and any headphone combination including the 2.5mm supplied headphones (E100).

It is obviously a bug with the phone itself. Has anyone got a fix for this PLEASE PLEASE PLEASE!
