K3S & PC Win10 Soundcard

I have WSJT-X 1.9.1 running fine with my K3S and Win10 on my PC. I'd like to
enable JTAlerts audio alerts using a TaoTronics TT-BA01 BT transmitter
plugged into my PC headphone jack but it seems any soundcard choice from
JTAlerts stops TX from my RIG. When I plug in the BT TXr I see a new
soundcard choice HEADPHONES (High Definition Audio), which is separate from
the one used in WSJT-X (SPEAKERS (USB Audio CODEC).

How do I get JTAlerts audio working without messing up WSJT-X TX?

Re: K3S & PC Win10 Soundcard

1) Configure your Windows Default Sound card to be but "new" card
(the one *not* your K3).

2) In WSJT-X set the audio to use USB Audio CODEC for both input and
output

3) In WSJT-X -> Settings -> Sound Card, set the sound card to
"[0] Windows Default Sound Card"

*NEVER* allow Windows to use "USB Audio CODEC" (the K3s sound card) as
the Default Device or Default Communications Device as this can result
in Windows' "noises," streaming audio, VoIP audio, etc. being routed
to the K3S (or K3 with KIO3B) and, if VOX is enabled, "on air" without
the operator' knowledge.

Re: K3S & PC Win10 Soundcard

Hi Joe,

So my PC looks like this:

SOUND CONTROL PANEL
Playback
Headphones (High Def AUdio Dev) - this is the new device that appears
when I plug the BT TXr into the PC Headphones jack
Default device (Green check mark)
Recording
Microphone (Logitech USB Headset)
Default Device (green check mark)

This seems to be what your 1) below suggests

WSJT-X File:Settings:Audio
Input Microphone (USB Audio CODEC)
Output (USB AUdio CODEC)

This seems to be what your 2) below suggests

As such, my rig does not TX.

Sorry, but I'm not sure what your 3) below suggests ... there is no Sound
Card tab under Settings, just under the Audio tab, where there is no (0)
Windows Default Sound Card option under Input or Output. What am I missing?

Thanks Bret/N4SRN

Then you have a configuration error in the K3S or K3 with KIO3B.
Are you using DATA/DATA A? Is CONFIG:MIC SEL = Line In? Have
you set the mic gain for 4 bars of ALC *AFTER SELECTING DATA A*
and *AFTER SELECTING MIC SEL= Line In*?

Make sure you have selected a TX tone between 1500 and 2000 Hz and
have the PWR slider at the maximum in WSJT-X.

JT-ALERT most Certainly has a "Sound Card" selection - it is the third
item from the bottom in Settings -> Manage Settings

Re: K3S & PC Win10 Soundcard

Hi Joe,

Yes, MIC SEL = Line In and I'm in DATA A. ALC is 4 bars solid and 5th
flashing on TX.

Got you on 3) JTAlerts is set to Soundcard (0) Windows Default Sound Card

I should clarify my statement on TX when the BT RXr is plugged into the from
Headphone jack - when WSJT-X is set to TX Enable and the K3S TX Red LED
illuminates, but ALC bars are absent (0 bars).

The Headphones jack is set as default and appears as Location 0 in High Def
Audio Properties, so it seems I have the BTRxr in the Headphone jack as the
(0) default device.

In JTAlert, the soundcard Test works and I hear audio alerts in the BT
earbud paired with the BT RXr. But no ALC bars. Pull the BT RXr out of the
Headphone jack and ALC bars 4-5 the next cycle.

Worth trying the rear PC soundcard jack?

Re: K3S & PC Win10 Soundcard

Bret,

If you look at the soundcard in the Windows Sound properties, what us
listed for output when only the K3 is connected? (Likely Speaker) Then
plug in the BT RXc - is the same output still listed and the headphone
added, or did Speaker get replaced with Headphones?

Some soundcards will not allow simultaneous Speaker and Headphone use.
Usually when the front panel jacks are used, the rear jacks are turned off.

WSJT-X does not use the soundcard path for TX enable, but the serial
port connection.

Apparently your BT RXc is turning off the audio to the K3 for some
reason - this is a computer audio path problem, not a K3 problem.

With Windows you *MUST* set up the sound cards before starting your
apps (WSJTX and JT-Alert) as the sound card assignments change every
time a sound card is added or removed.

Your symptoms indicate that WSJTX is configured for the default audio
device (or only audio device if the "BT RXr" is not connected).
Connect all of your audio devices, configure the default output device
with (Windows) Sounds -> Playback -> "BT RXr" as the default device (and
default communications device). Configure the default input device
with (Windows) Sounds -> Recording -> "Logitech mic" as the default
device (and default communications device).

Once the defaults are assigned - *without adding or removing audio*
*devices*, start WSJTX, select File -> Settings -> Audio and make
sure Input: "mic (USB Audio CODEC)" (Left) and Output: "speaker (USB
Audio CODEC)" (Left).

After that, start JT-Alert, Select Settings -> Manage Settings ->
Sound Card and set "The Sound Card used to play the audio alert
(wave) file to "[0] Windows Default Sound Card".

If *at any time* you change the sound card(s) attached to your
computer (including the K3S/K3 with KIO3B) you will need to close
WSJTX and JT-Alert, reassign the default devices, restart the
applications and reconfigure their audio devices. The devices *may*
keep their (device numbers) assignments but they may not - and will
*most certainly not* if the a new device has been added or a device
has been removed.

Re: K3S & PC Win10 Soundcard

Joe is entirely correct about this. Anytime you add a soundcard,
Windows will try to make that new one the default card. That means that
system sounds will go out through that soundcard you just added. That
goes for the internal USB AUDIO CODEC in the K3S or any other USB
soundcard as well.

So when adding any soundcard for digital modes, check to be certain it
is NOT the default soundcard after it is installed.

Windows does not know about those of us who use soundcards for purposes
other than playing music and making the Windows Beeps. They assume that
we are all consumers who want to listen to our music through the new
soundcard - that serves the majority of their customers, but not those
of us who have a different purpose.
