The easy and 100% solution is to turn off Windows sounds in the control
panel. After all, we've heard those things in the shack and office for
years and long enough and who cares about some stupid ding dong that
contains absolutely no intelligent information.
I'll also add my comment regarding using the headphones signal for the RX
audio to the computer as it is after the volume control and thus affected by
same. Better to use the line output on the radio which is before the
volume control thus allowing one to turn off or to turn down the volume if
they so choose and thus not affect the signal to the sound card.
As to feeding the audio into the mic input, again, not a good idea specially
if there is a line input available for the TX signal. One is much less
likely to get hum and ground loops and RF in the audio as the higher level
provides a much better S/N ratio. My general rule is; "if it is not a mike,
then don't connect it to the mike input". Works every time.
The exception to using or not using some type of interface is ones
preference to use PSK. That does require an interface and related
connection to the radio. The use of AFSK is generally more accurate and
easier to interface and operate.

Yep... I can see your point Gary, but abandoning the principle of
parsimony in the face of improbable events of little consequence seems
unnecessarily restrictive.
Myriads of VOX stories with unintended consequences abound. But in the
grand scheme of things, the smoke goes up the chimney just the same.
KISS by using VOX as Ed indicates, decreases the entropy caused by the
added complexity of the interface -- this is overall, a good thing.

RE: Using VOX.....
If you happen to "view" a multi media file with sound, the sound can
transmitted over the air as it trips the VOX. Using a serial port
(or USB to serial) to initiate PTT provides control to avoid
accidental VOX transmission. I've made the VOX mistake and I often
hear others sending audio instead of PSK-31 data.

Right on! I've used VOX to key the rig with MixW and Fldigi across
many rigs: FT920, IC706, IC7K, Pro3, and a TT Jupiter. Works slick
and
easy. Two cables: one from the soundcard to the mic input of the
rig;
the other from the rig audio (headphone jack works) to the sound
card.
That's it. Save your money!

Less parts, less cables = less problems.

Lloyd, what kind of switching are you using for keying your O? i
use
MixW and have it send the keying to a COM port. the switch i use
is
one
shown in the MixW help file. you can set most any COM port or USB
to COM
port you choose in MixW.
