So a new problem appeared last night when I was quietly listening to
WSFM at a low-level volume. After about half-an-hour, the Touch went
ballistic, producing a very harsh and high-level mix of a very loud
buzzing sound with what almost sounded like carrier noise, very, very
loud, scaring the hell out of me at the time. The only way I could stop
this was by physically unplugging the AC power supply. The Touch would
not respond to any of the remote control commands such as reducing the
volume or even trying to switch the unit off. 

When I plugged the power back in after a few seconds, all was good and I
could select stations again - for about 10-15 minutes then a repeat
performance of this incredibly loud sound, much akin to a heavy
thunderstorm with hail on a bare corrugated iron roof.

This happened five times and then I gave up and went to bed. 

I have not tried it today because we had an electrical storm this
afternoon and I did not want to risk frying my VDSL modem or anything
else. What I did do was to check the Walmart type power supply and it
seems fine, DC voltage is 4.94v and there is no sign of any AC ripple on
the DC output.

Has anybody ever experienced this? This throws quite a damper on the
brand-new (albeit some 8 years old) SB Touch unit.
