[NFBCS] Audio Cutting Out

[Brian Shell]

Hi Leslie,

Your situation sounds similar to mine.  Changing the JAWS sound card to 
something other than default has no effect on a computer with only one 
sound card.  I think the JAWS avoid sound cutoff feature is an attempt 
to work around the issue.  JAWS sends silence to the audio device which 
is still an audio stream so some speakers see it as audio still playing 
so they don't turn off. However, I have Klipsch ProMedia 2.0 speakers 
and a pair of Mackie HR824 and both of these turn off because they 
detect based on loudness of the audio. I suspect that is the case with 
all wired speakers since they receive analog signal and not data.   My 
Mackie speakers have a hardware switch to disable the standby, but the 
Klipsch speakers do not, so for those I have to wake them up with JAWS 
key + F12 or similar.  You might try a cheap pair of wired headphones 
(1/8" or 1/4", not USB) if they work then you'll know it's your speakers.

Hope this helps,

Brian
