software problem on K3S - software lose 2nd speaker!

Paul Kirley-2
SPKRS can switch to 1 automatically if you use mono speakers or there is
an accidental short between the right speaker leads.  Check your speaker
plug and wiring.

From firmware release notes:
**************************************
MCU 3.14 / DSP 2.16, 5-9-2009

* SPEAKER PROTECTION: If you’re set up for stereo speakers
(CONFIG:SPKRS = 2), but insert a mono speaker plug, the right speaker
output will be shorted to ground. This can cause excess current drain
if you turn volume up to high levels. The K3 now detects this condition,
automatically turning off the right channel (SPKRS = 1).
