Audio switch
A very long shot, this...
I'm an owl, married to a lark. She often turns in around 9pm. I'm usually more around 2 am. To prevent the noises-off from my computer disturbing her kip (she can hear a pooter beep from the other end of the house through several closed doors), I have a timeswitch on the power supply to the speakers. That shuts them off at 10 pm.
That works well, but it means that after 10pm if I want to listen to anything, I have to go into the Audio Properties panel and switch to "USB Headset". Anything running at the time (ie the program I started before I realised) then has to be shut down and restarted.
So ... the question:
Is there a way to set up an automatic "software switch" to change from Speakers to Headset at 10pm?
If all else fails, I'll do a job with a relay in the speaker line.
