T480 audio function user hostile

[keithsketchley]

Frequent problem getting audio out of T480 running Windows10Pro.

Have to:
- turn RealTek Audio Console ON, set volume in it
- for good measure turn Dolby on to be sure
- volume control on keyboard to row (ensure not Muted)
- of course if using headsetcheck its volume control
- if using wireless headset or speaker ensure it is paired (Bluetooth usually)
- something else

Repeat after rebooting of computer.
(Good practice periodically, off at night if environment not secure, necessary for some SW updates.)

Headset jack works.
External speaker via Bluetooth works (JBL Flip5 is a nice one at modest price)

That isolates problem to internal speaker function.

I'll add to this post later.
