    I need help troubleshooting a speaker issue with my Sony STR-D315. The Left speakers in both the A and B channels don't seem to be working properly.

    The facts:

    [*]A speakers = 8Ω
    [*]B speakers = 4Ω (I know, I'm playing with fire)
    [*]When only one channel is selected (either A or B), the left speaker on that channel produces sound, but so much quieter than the right, it's imperceptible unless the balance is all the way left.
    [*]When both channels are selected, neither of the left speakers produce sound.
    [*]It happens throughout all modes.
    [*]The balance is adjusted properly.
    [*]Muting is off.
    [*]The manual indicates that it was designed to play both channels simultaneously.
    [*]I opened it up and vacuumed out the fuzzballs.

    Any thoughts?
