Comment 62 for bug 871808

I don't know it for sure, but with the previous tests I heard no sound coming from the sub with the rear left test signal, but did with the rear right. The sub connector has 4 wires: 2 connected to the sub's voice coil and the two others to a resistor (I think dummy load, could be used for dectection of sub presence on the left channel). Ah wait... while writing the previous sentence the next idea rose: both channels might be (able to be) used. But because the left channel is hooked up to a resistor it off course cannot be heard. So still (L+R) might be used...
I did the tests you asked for anyway, the log is over here: http://pastebin.com/hrjY1d2y
