Hi Charles,

thank you for picking this up so quickly, much appreciated.

You were right to let me check this, headphones via the 3.5mm 
audio jack do indeed not work. They are not even detected, it 
seems. Sound just continues to play through the speakers.

Does this mean faulty hardware is the most likely option? This laptop
is barely a week old. Or is it possible the driver left the chip in a non-
working (but potentially recoverable) state?

Thanks!
