In Win 8.1 right click on the Start button then click on Search. Type WL that will get to Sound Board Mixer Control. You can change the default sound card there.

I recently installed a second sound card in my PC.  When I did, the OS
(Win8.1) grabbed the new card and made it the default card.

I want to go back now and reassign all the ham radio applications to the
original sound card, as I already have everything cabled up to work with
this card.  I will use the new card only for Windows sounds.

I have been able accomplish this reassignment with all my ham radio
applications except for WriteLog.  I am unable to find a menu item that
allows selection of a particular sound card.

I did find this web page:

http://k9jy.com/blog/writelogini/sound-card/

which advises editing the writelog.ini file to include

[WlSound]
WaveOutIndex=n
WaveInIndex=n
MixerIndex=n

I've done this and, testing via the WriteLog CW decoder, still don't have
any audio coming into the decoder.  I've tested with values of n=0, 1 or 2.

Am I on the right track?

Does it matter where the [WISound] entries go in the writelog.ini file?

If it makes a difference, I am using WriteLog v11.17E, and I am editing the
writelog.ini file located in c:\Windows.

I decided to try an external USB sound card for the mic input.  I
purchase a
SYBA SD-DAC63094 for $30 from NewEgg.

For several years, I've been recommending Tascam and Numark USB sound
cards designed for musicians and DJs for digital modes. Both are now
discontinued, replaced by newer models, but the newer Tascams are fine.
Both old and new are widely available on EBay at greatly reduced prices.

Poking around N8LP's website a few weeks ago, I saw that he is now
recommending an ASUS sound card for bringing quadrature IF outputs into a
computer for his NaP3 software. B&H in NYC is currently selling them for
$70. 192 kHz, all the ins and outs we need for both SSB and digital modes.

There is GREAT virtue in using a sound card of this quality for digital
modes. I experienced modest, but noticeable improvement in weak signal
decoding RTTY when I switched from the sound card internal to my Thinkpads,
but the improvements with K1JT's WSJT family of modes is dramatic -- the
USB units decode twice as many signals per pass and regularly 10-12 dB
deeper into the noise.

I wrote up my test methods in a report that also includes a tutorial on
setting levels. http://k9yc.com/USB_Interfaces.pdf

Here's the Asus unit Larry recommends. My neighbor, N6NUL, bought one and
loaned it to me the check out. So far I've only looked at WSJT decoding,
which is quite good.
