Hi Smuggers,
I bought a Logitech H600 wireless headset in the endless quest to make
endless online teaching and meetings work better and at first it worked
really well. It has a radio unit that plugs into USB, rather than
bluetooth.
Then today we had a power cut (!) and my Mac pro went down, of course.
On restoring everything, there is ferocious interference on the headset
mic in particular but also the headphones. However, on my laptop they
continue to work perfectly. I've tried different USB ports, SMC reset,
PRAM reset, starting from a clone of the hard drive and several
restarts.
I can't think of anything else to test and am a bit mystified (using
different start-up disks shows it's not OS, and proving different
machines work shows it must be the Mac Pro but 'under the OS'. But what
is there to reset apart from SMC and PRAM here? (I guess I'm looking at
firmware but have no idea how to fiddle with that and am not sure I
should...)
Cheers,
Jason
